I'm going to work up to 30.5grs of Varget with the 105s. I should be able to get 2850-2875 with that load, which is fine for me. If it doesn't work, I can always shoot out the 6BR and go GT. |

Everyone wants to run the 88-95gr bullets, but if you actually look at the BC/velocity numbers, you’ll see that the 80gr bullets are the better performers for most applications aside from maximum supersonic range (and that’s very close in most circumstances) and with <18-20” barrels. The 6.5creed is similar with 130’s vs 140’s, but to a lesser extent. More powder offers greater flexibility. And you can’t go wrong with the 105 hybrids. That’s what I chamber for….just waiting on my order of 1500 to eventually show up. Working with 107/110’s till then. |

You just have to be fast on the draw. I work from home so the moment a discord in-stock notification lands, I can hit the site. The Varget I got was strange, it popped up early in the morning probably before the west coast guys were even awake. |

Can't let our thread go to page 2.. That and I'm moping around the house after getting surgery so an overly complicated post to post what most of you probably already have tried seems appropriate:
Sometimes load development is easy. A while back I had read Mark Gordon's article on load development (https://precisionrifleblog.com/2020/03/29/bullet-jump-load-development/) and figure I'd give it a try as I was loading some Hornady 140 bthp's for my AI in 260. If you haven't read the article, basically (very basically, lots of other points in there) the theory is a longer jump is more stable, and to try .060 - .080 jump instead of the standard .020 jump. I think it says somewhere in there, Hornady jumps about .070 in their factory ammo from a SAAMI chamber and their ammo usually shoots pretty well in most rifles. So I measured the jump of the 140s in my Proof barrel, took .070 off, and not so suspiciously it matched up exactly to the recommended OAL in the Hornady book. Loaded up a few charges in an OCW style test, found my target velocity and all the groups were really about the same size. Found a charge between two similar POIs, loaded up a few and shot that group, .500-.264 = about a good a group as I'll ever shoot. Fired a total of 18 rounds to find my new load. 41.5 of H4350, 210M, Starline brass, 2750 fps. Yeah I know three shot groups don't count, but I think it'll do just fine. |

View Quote I'd say that looks pretty darn good! I was speaking to the AI guys in their Fredericksburg shop one day while they were in the back cleaning barrels to get ready for a match. We talked about load development, jump etc. They are big believers in a load either shoots or it doesn't and they don't agonize over ladder tests, jump, etc. They also load longer akin to Gordon's theory. When my 6BR arrives, I'm just going to load up 30.5grs of Varget over a 105 Berger at a 0.020 and see if it works. I've been busy this summer, including more work at the Quantico Shooting Club to get the infrastructure stable. I spent last week power washing the club house, the picnic tables and the shotgun barrier fences (22 panels), the shotgun walkways (those circular power washer heads work wonders). It took me 4 days to get the fences ready for stain. I rented an airless sprayer and stained the fencing Saturday. It was incredibly quick but geeeeeeeezus, I went through 15 gallons of stain, the boards just sucked it right up and I had to do two coats to make a dent. |

Have we all retired the 'ol Larue 260's?
Mines in the back, for now. Wanting to compare it to a Seekins 260 at some point. For now I picked up a Seekins 6mm creedmore bolt action to play with. Sighted it in at 100 then took it to 1080. It's quite the soft shooting mOshene. Attached File Attached File Attached File Attached File |

I think we still shoot our .260's, but as with any enthusiast, we migrate platforms. Heck, My 7.62 tOBR hasn't seen the outside of the safe in 3 years.

With my schedule I’m lucky to do much of any shooting, but I did just load 200 rounds for my tOBR should the opportunity present itself. I doubt ill shoot all of them in the calendar year though

Nice work!
My my what a big case you have! |
|

That’s a lot of gun for 600 yards, that poor steel lol.
I found a new load for my 6GT and fine tuned the zero with four different three round groups. The biggest was in the .3s. I don’t think I’m that good of a shooter, this little round is phenomenal. When you burn out your BR you might want to consider it, although it sounds the BR is even easier to load for. |

Took the Seekins 6mm out today and got some video.
On a side note the Arken scope that got rave reviews on the Hide is no Bueno for me. Hazy! It's going back for repair/replace. Stole the Nightforce off the .260 for now. Seekins Havoc 6mm Creedmore @ 988 Yards |

1st target was pretty good sized , 2nd one not so much.
Picked up a Vortex Viper 85mm spotting scope and a Novagrade phone adaptor. Euro Optics at about half price. Works pretty good at the lower magnifications for video. Have to crop part of the video out on the left edge which has some of the scope in it. Also got a remote shutter control for the camera on my phone. Works most of the time. Got a bunch of rapid fire video with the Larue Grendel at about 680 and I thought I was hitting the target. After reviewing the video I was mostly hitting right in front of it! Next time.

Those were quail. Didn't see them until I reviewed the video.
Got the Nighforce installed and dialed in on the 6mm. 5 shot groups all touching. Also tried the Larue Grendel with wolf steel cased ammo against my reloads. Wolf was around 2659 fps and my loads were 2473. None of the groups were decent though. Something has changed with my loads. |

View Quote Frank has been great about letting ppl know the status of materials. Back when ‘Rona first came on the scene he warned of increased lead times. Even though I had a new 223 and 2 new 6 creeds, I went ahead and grabbed 5 blanks so I’d be able to spin up a few barrels as needed while supply caught up with demand. I’m a bit impatient when I get the itch for something new. Not to increase any panic buying, but if you see a barrel that you may need in the next few months to year, it’s probably not a bad plan to go ahead and purchase if you have the means. |
