11.6gr and work down.
OAL 2.260” This is from Hodgdon’s site for the 208 Amax. I don’t load 208s but I loaded 217s and 220s with it and they both ended up in the low 9gr range. That’s for an 8” barrel. In practice CFE BLK is best suited for heavier subs. 208s should be fine but there are much better options for supers. CFE BLK is very much a middle of the road powder. Not quiet, not super loud, not the dirtiest, not the cleanest, etc. I prefer N120 but CFE BLK won’t cause you issues outside of the noise. |

I loaded a dummy round and my lee die wont adjust enough to get a 2.260 oal. The bullet is barley in the case at 2.150.

Should have plenty in the case at 2.26. This is a pic of factory Hornady, and while I’ve never bought this exact load, their factory offerings usually share OAL with their reloading guidelines, so I’d assume this is roughly what 2.26” looks like.

Sorry I messed up. The bullets were not 208 amax. I bought a bag of 220 grn bullets of unknown origin. The amax gave me 2.260 just fine. I dot know what to do with these mystery 220s though. At 2.260 the cannelure is 1/8 in from the case mouth. I would like to load them for my HR .300blk single shot. but dont know where to start. I guess thats why they were $4 for 100 at a yard sale.

I’d load a dummy to 2.26, and see if it chambers (don’t crimp it, but take the flare off). If it doesn’t, seat it 20 mils in and try again. Repeat until it does. Then go in another 10-15 mils for good measure.

Below is the hodgdon rifle data link. http://www.hodgdonreloading.com/data/rifle The only load data I have for 220s are the Everglades plated that I extrapolated from several sources so take it as you will. It may give you a starting off point though. Loaded to 2.260 OAL. 10.3 barrel where I was looking for a decent load to shoot suppressed with relatively okay groups. 12.8 grains on the high end that got me min. 1103 - max 1131 fps. and SD of 10.6. 11.8 grains on the low end with a min. 934 and max. 1024 fps. and SD of 37.2. I settled on 12.0 grains which keeps me under 1050 and general SDs in the mid/high teens so far. |

But 300 blk can use bullets not designed for it, and that's why the cannelure is above the case mouth. *Seat to your desired OAL and ignore the cannelure in this case. $4 was a good price, shoot them up.

Thanks for all the info. Im worried about seating them. What is the least amount of bullet you can seat in the case? I dont want to overpressure with it too deep. Maybe I can measure the min amount and mark it on the bullet and seat it to that depth and try it.

Can you seat the bullet to the neck shoulder juncture and measure? What’s your OAL? If too long, seat to the shoulder-body juncture. Measure. OAL? I would say seating to the neck-shoulder as a minimum in a semi-auto for neck tension. Seating to the shoulder body as a maximum. Seating to the shoulder-body juncture uses about the same cartridge space as most BT bullets. I suspect you have a 30-30 bullet which can be used but the cannelure will not be in the right spot for the 300. Ignore it. You can seat bullets outside of the suggested range above but requires special needs. I load a 30BR that only uses @25% of the neck but it is jammed to create pressure that is lost on neck tension. I load heavy for caliber 6.8 where the cannelure is no where near the mouth just as you describe with you loading. |

With most heavy bullets, seating depth (length of the bullet) seated into the case will be pretty substantial, which is offset by the lower charge volumes. Someone please correct me if Im wrong, but I think its not typical that you have to worry about overpressure situations in 300 blackout, especially with heavy subs. I just don't think you can get enough of most of the current powders into the case to cause this. It MAY be possible with really light bullets and fast powder, or if you start loading too long sticking the bullet up into the lands on chambering. |

Over pressure is a non issue with 300 BLK subs if you are actually charging them to sub velocities. Supers are a different matter. |

Thanks again guys. So i can set the bullet 1 bullet diameter in and load it. OAL will be 2.150 and I dont have to worry about pressure because of the light powder charge. Thats what I thought, but the load data for a 220 bullet is 2.260 which I cannot get with these. I counted and got 225 220 grn bullets for $4. I got 40 fully loaded .308 soft points for $4, a bullet puller for $2, large rifle and pistol primers for $10 a box of 1k, unique 1lb containers for $10 and imr 4401 for $10 as well. Plastic bullet boxes for .50c I spent $180 in total on all the stuff. Took me 3 trips to my truck.

Pull them down with your new bullet puller and reuse the primed brass and projectile. |

Now Im looking for something to weigh the powder for my cases. A beam seems too slow and cheap auto chargers can drift. I need something affordable quick and accurate. ? Under $100 would be great. Any ideas. Ill only be loading .300 for the foreseeable future and mostly subs so bench rest accuracy isnt needed at this time. |

Ill only be loading .300 for the foreseeable future and mostly subs so bench rest accuracy isnt needed at this time. Beam Scale. Check out the RCBS/Ohaus 505 scales. I think Dillon has a rebranded 505 as well. A beam scale is only used to get your powder measure set up properly. Then only every so often just to make sure everything is staying adjusted properly. Some check every 10, every 20, or maybe even every 50 rounds. Personal preference here. I’ve never had an issue with my PM drifting on me and I rarely load near max, so I don’t check as often but that’s just me. A cheap digital could work for 300 subs but personally I found them to be a headache. Either Beam, or drop $450 on an FX-120i. Some people will say autochargers are worth it but again, many different opinions here. I have a beam scale and an Autotrickler with an FX-120i. It is overkill for most people including myself but it was definitely a splurge purchase. The beam scale isn’t bad. |

What do you use to throw charges if you just use the beam to check them every 20 charges? I did buy a lee scoop set for $3 off the guy as well. |

A piece of equipment called a Powder Measure. I use one similar to this Lee You have an adjustment screw that changes the amount of powder dropped per “throw” - so you throw a charge into your pan, and weigh it. Then adjust as necessary. |

Throw the charges with a powder measure, get a quality one made of metal. The scale tells you when the powder measure is adjusted correctly.  This is my set up. Beam scale mounted an a strong level shelf at eye level. Powder trickler right next to scale. Just to the right of the scale is my powder measure for a smooth work flow. You may find it beneficial to read up on the basics of reloading. Lyman 50 has a good "how to reload" section in the front and loading data in the back. A great manual. |

I would NOT buy that plastic Lee powder measure suggested above.
I just bought one and returned it. It sifted powder(flake) out the sides of the powder measure cylinder wiith every drop. Save your money and buy a used RCBS Uniflow and then get a small cylinder and stem from rcbs for $43. |

I bought a uniflow locally for $93 and a redding beam scale for $82. Made my first bullet. 10.6 grns of cfe. Didnt keyhole. Ill up it to 11 and try that tomorrow. I figure Ill increase the charge to max. If none keyhole then Ill try them with a can to see what the highest charge I can get to stay subsonic.

And I’m guessing from the charge weight that load was with the heavy amax bullet? The reason I ask, cfebkack is a low pressure powder and will not cycle my 8” 300BO with light bullets without a suppressor. |

Be sure to report back if it runs suppressed. I seriously doubt there is any chance cycling unsuppressed. Also, if you are running dedicated suppressed I wouldn’t worry about the powder. Cfeblack is good here for less gas in the face due to the low pressure. I like to find loads that work both ways in sbr. I do have a 6.8spc with a Wilson 11.3 barrel that refuses to cycle subsonic unsuppressed. I may try H110 here with srm primers to see how it works. |

i found the load data on a link on the website. 11.5 cfe 1060 fps, 12.1 1125 fps. 11 it is to start. All these loads are subsonic so I will shoot them suppressed. Thats the idea right? Otherwise run supers. They are cheaper. I have 110 125 147 180 grn bullets I bought to play with later. Thanks for all the help. I cant wait to start ringing the steele with my own loads tomorrow.
