If anything chamfer the inside, make sure the surface the base of the case is sitting on is free of excess powder and that your bullet is lined up properly with the case. The case OAL per SAAMI is 1.686 -.020 and we aim for 1.676. But roll crimps can be sensitive to the over all length of the case.
I would go with a Lee collet type crimping die for a .270 caliber, but you more than likely would have to have the capablities of shortening it up to make it work. Art |

Dirty powder is not really a factor to me. Guns get dirty, oh well. I'm more concerned with accuracy and velocity. That being said H322 seems clean in my rifle. As far as I know the only powders that are accurate and fast in the 6.8 are H322 and Rl10x.
I've only used 6 or so powders but none were as good, fast, and accurate as H322. FWIW........ |

Believe me this is an outstsanding load. I have tested it in a 20" barrel and get about 2720fps. The case is near full to the base of the neck so it is at approx. 100% case capacity. Being a ball powder it meters quite welland it is very clean. Over 2000 rounds have proven this is an accurate and consistant load. Loader: CaptSchofield Powder: 31.0gr AA2520 Bullet: .277 115gr Hornady & Sierra OTM Primer: Win larger rifle Brass: Remington OAL: 2.295 just short enough to fit in PRI mag. MV: 2580-2600fps from 16” model #1 chrome lined Notes: have used the 110X Barnes with same load as above and is slightly faster loaded up to 31.5 with the 110hornady Vmax. |

Question from a computer illiterate. I'd like to post Pic's of my son's deer he took with my 6.8. I need instructions on how to post (instead of just hitting "Reply"), and how to attach a couple of pictures.
thanks |

1) load the pics onto a photo hosting service (hunt101, a MSN Site, etc) 2) get the URL of that file 3) When posting click on the 'photo' button (the one that looks like it has a picture of a mountain on it) and enter the URL from #2 into the box that pops up on the screen. That's it. |

Wow. Thats a little too much for me, so I'll post the story and if anybody wants to see pic's you can send me a msg at [email protected] and I'll send 'em.
In Kansas we have a youth and disabled hunt weekend early in the season for kids up to 16 years. Only the kids can hunt, and have to be with an adult. Kansas regs say bullet dia. must be .23 or larger, thats the main reason I went with the 6.8. I wanted an AR and wanted to be able to hunt with it also. That being said, my son's first day hunting deer (he's 13) he took a good sized western Kansas mulie buck. It was late in the day, and we had hunted several large pastures with no sightings. We got in some trees in a waterway surounded by milo fields at about 5:30 in the evening. At last light the buck appeared and was making his way towards us. I gave him the OK to shoot when the buck was about 45 yards and broadside. He hit him pretty low (nerves, this kid just ran 120 rounds at paper the weekend before and can hit well) and open up his lower belly. He kind of "bucked and ran" to about 120 yards and turned broadside again. I told him to hold steady and shoot, and he let 'er rip again. This one was perfect. Hitting midway up the rib cage on the right side right behind the heart. I'm using the Hornady 110gr V-max pushed by 29gr of H322. Hornady brass w/small primer. The entry wound was quite large (I could put my thumb through it) as would be expected from this rapidly expanding bullet. The lung area was completely destroyed, and the remaining projectile exited through the left ribcage right behind the left shoulder blade. I found what was left of the bullet lodged in the skin when I was skinning. The remains are solid and intact, weighing 51.8gr and the lead measuring 0.418 at the widest spot. I have some excellent pic's of the bullet. This was the first deer I've taken with the 6.8 and am very pleased with its performance. Its great for kids too, due to the low recoil. I'm also pleased with the 110gr V-max. This experience proved to me that this can be a good projectile for med sized game at reasonable ranges. If you have any ?'s feel free to e-mail me at the above address. |

Congrats to your son Heliflyer1. That's a nice buck. I hope to use my 6.8 this year for deer. I've been working up a load using the Barnes 110 grain TSX bullet. I was having some pressure signs with 29 gr of H322 until I switched to CCI LR primers rather than the CCI Mil spec (magnum) primers. Now I get 1" groups at 100 yrs with no pressure signs. I can't wait to see what they do to a white tail.

I've seen several postings of guys taking whitetails with their 6.8's, but have never seen another of a muley. Does anybody know of another muley that was taken? I told my son that he is probably one of the first to do it. Just wondering. |

Those are Hornady bullets.
Hornady's part # for the .277 dia. 115 gr. BTHP/WC is #2715. Notice how LS&B used basically the same numbers in their item #. Thats an extremely good price. I think Midway sells them for around $16 per 100. Thanks for the link. |

Just put together a 6.8 CMMG 16" mid upper on a DPMS lower I had.
I looked through this post and could not find any loads for the 100 grain Remington Core-lock. I loaded up a few over 29 grains of H 322 and CCI br primers in new Remington brass. I'll get a chance to shoot some tomorrow. If I can I'll take my chronograph and test these loads for accurracy and velocity. I did get a chance to test the rifle with factory Remington 115 otm and it functioned perfect. I was getting 1.75" groups at 100 yards using a stock Bushmaster trigger set at about 8#. I'll take my other lower with the Jewell trigger and see if I can get tighter groups and report back tomorrow. Jim the Plumber |

Rather than use the Vmax on deer, I have had great almost equal accuracy out of the Sierra spitzers, 1/2 " at 100 with 29.2 grains of H322. And cheap to boot . I tested the TSX's and I found them far less accurate than the Sierra's or the Vmax. Thats just my cheapo Model 1 upper but I can get 3/8" with the Vmax's all day long.

I went to the public range today to test my new loads. Unfortunetly my club was closed due to some ESPN SWAT competition they were filming. While the public facility was nice, the overhead cover (to supress sound) blocked the sun so my chrony was nonfunctional
 . So I just fired a few of the test rounds to see what the cases would look like:115gr FMJ/28.2gr H322 : very hot load, the primer was very flattened and I could see a 'swipe' due to the ejector. 115gr FMJ/28.1gr H322 : Better, it ran fine, no marks on the brass and the primer looked good. Group size was just under 2" (but I'll say at this point most of my groups were in the 2" range as the barrel was very warm). 110gr VMAX/29.2gr H322: another REALLY hot load (over max) Primer was very flattened and there was the 'swipe'. I won't be loading any more of this. I started by shooting my 'standard' 110gr VMAX/29.0 gr H322. I brought along 20 of these for zeroing. I shot three 1" groups that overlapped (shot 1 group adjusted 0.5" d/r, shot another 1" group which overlapped the first, adjust .25" d/l, then shot the 3rd 1" group). However within an hour (after shooting the other rounds) I could not shoot another 1" group (it was almost 2" - but the barrel was very warm). I'll clean the rifle and re-try for the next range trip. |

What brand of brass were you using? What was the COAL? I am finding that:
115 Hornady BTHP 27.5 gr. of H322 CCI #34 primer Remington brass ('04 manufacture) COAL 2.295" Velocity-2498 fps ES-52 fps SD-24 fps produces ejector swipes in my 16" WOA SS barrel (just recently built). The primers are not badly flattened but then they are a harder cup. I haven't tried it in my 20" yet. |

I went a good many years w/o one. It really is nice to chrono loads when working up loads. It sheds a whole new light on the loads and why they are working/not working. It can even help you see the wall in pressures. When working up a load to max you will often see a relatively equal increase in velocity (ie .5 gr. icreases in chargegiving say 50 fps) but many times when you get close to the max this increase will decrease or sometimes make a dramatic jump. The irregularity gives you a sign to pay close attention. |

I only use Silver State brass. The few pieces of Remmington I have I keep for dummy rounds. COAL was 2.26 for the FMJ, 2.27 for the VMAX.
In what barrel length? At 28.0gr of H322 I'm just getting a hair over 2400fps from the 115gr Remmington FMJs. |

Sure would like to know the magic formula (load) for obtaining the at least 2700 fps for a 115 gr. bullet out of a 18 inch barrel with my 6.8. So far the best I've been able to get is 2450 fps - It is nothing like all the claims in the gun rags.

Try Captain Schofield's post on pg 21. Third from the top. He is getting 2720 from a 20".Somewhere in the last few pages someone was having some luck with 4198 I believe. |

Posted: 10/22/2006 10:19:36 PM EDT

Early remington ammo that all those claims were made from was loaded to higher pressures. Remington has since pulled the velocity ratings back by 200fps. So, the 2700fps claims became 2500fps. You can surely overload your own ammo to meet these numbers. Just don't be suprised when the brass or bolt life is shortened. Remember that factory ammo is NOT loaded with the concerns of the reloader in mind. I probably have some OLD remington ammo if you want a box to compare. |

FYI I took the 6.8 out on Saturday too, for some 300y fun. I was trying out my new C-Products 6.8 SPC 15 round magazines. I had ordered a couple to try out when I ordered some of their 5.56 20 round magazines. The 'stainless' 6.8 magazines look and feel almost exactly like the 5.56 cousins with the exception of the brown 6.8 followers (the 5.56 magazines had grey 5.56 followers). The magazines performed flawlessly, however I prefer my PRI 'military plate' magazines. The C products is just too close in looks to the 5.56 magazines (down to using the standard USGI floorplate) that I'm concerened I'll grab the wrong magazine from the bin.

Are those mags long enough to function with an OAL of 2.295. In other words is the internal length (as far as the cartridge goes) the same as the PRI mags. I have been thinking about getting some but have been concerned about that. |

I'll check for you tonight. It hasn't been a concern of mine as I load to 2.26"-2.27"

Posted: 10/26/2006 6:32:48 PM EDT

Ok I took the measurements.
I ran a caliper from the rear corner to the center of the front of the magazine. I did this because both are points I can hit consistantly and I noted the center line on the C-Products magazine was thicker (overlapped metal) than the PRI magazine. C-Products: 2.288" PRI: 2.333" Definately more room in the PRI. |

I own both brands of magazines and haven't had any issues with either one. I am using one kind of magpul on my 6.8 mags (ranger plates) and a different style magpul on my 5.56 mags to eliminate the confision. You could go one color for one caliber....

I do not own any CP 6.8 mags (hoping the GB will change that), only PRI mags for a total of (5) 15 rounders. Two are one length and the other three are a bit shorter. I have had some issues with each mag from time to time. You can definitely see that some of the mags allow the follower to approach the feedlips further than others. I tried to search for the thread that mentioned the fix but could not find it. Any thoughts? |

I had a few problems with the PRI's. These are early ones with the steel follower. I had a problem with the front edge of the case mouth catching the front edge of the mag. Filed them down until they didn't catch when pushing rds. out manually by hand. The steel followers in mine seemed to drag a bit. took them out and bent the front and back straps inward just a tiny bit. Seems to have helped. Some of the bead from the butt weld in front was a bit large so I filed it down a little. Just took the higher spots off and that helped things a bit more. The thing that has me discouraged with the C-Products mags is that I load my own ammo out to 2.295" and do not want to shorten it. |

As far as I can tell from my research: SSA combat load OK:
SSA combat load NOT OK:
SSA combat load UNKNOWN:
Anyone else have more info? |

The table needs to be updated since many of the vendors have verified SSA compatiblity.
I noticed many reloads are using the H322 instead of the H335. What are the main points of this? Thanks! |

Actually, he has a pretty good start because he is talking about the "COMBAT" extreme bullet loads, not the standard loads. You may not be aware, but there are two different pressure levels of SSA ammo available. The initial problems were with the high pressure ammo. Now that the lower persssure ammo is out, the compatibility problems are going away. That's why you are hearing about companies saying their barrels are compatible with SSA ammo now. This ALL stems back to one specific "extreme" bullet. If you use ANY other of SSA's loads, there are no problems.
The COMBAT loads are only available directly from SSA now, even though there are a bunch of them still floating around the distributors. Art and my opinions on chamber design and bullet construction differ quite a bit. Art does not recommend the COMBAT load in SAAMI chambers. I cut SAAMI chambers, but will also cut the 6.8SPC #2 which has the longer throat upon request. My opinion is that all ammo/bullets should be made to comply with a SAAMI spec throat. Art's opinion is that the SAAMI specs are invalid because they are not conducive to his COMBAT load. While I agree with him that the specs COULD be changed, it has not happened and likely never will. Hence, we have the 6.8 SPC #2 design with the longer throat. |
