If the subs aren’t sticking, it’s probably the bulge you found creating the hang up. I would measure the base to datum length before and after the subs. If you pull up a SAAMI drawing of the chamber it will sort itself out, but base to datum on the shoulder needs to be at least 1.071”. Less than tha...

Hey guys, just got home and sat down at my reloading bench. Oddly enough, I had one round left from yesterday that has the 185gr Bergers loaded into it. I previously had loaded some 220gr sub sonic loads. For shits and grins I took the gun outside and chambered one of my subsonic rounds and had zer...

Hello everyone. New to the group and also new to the 300 BLK platform. I'm experiencing a huge issue with my setup. When there is a live round in the chamber the bcg is very difficult to open and clear the chamber, but the bigger problem is with my brass once it is fired. The neck is being stretche...

I would max out the load and work back. Probably 10.5 grains at 2.26”. That might go super depending on temp but probably around 1125 fps. If that does not get the bolt locking back it might be a bad combination for the Rattler. If the 10.5 works, depending on velocity, Then drop the load to split t...

Do you have a load that does lock back all the time?

How about posting current, complete load data and is this with without a suppressor that you can’t get bolt lock?

I generally start with a a powder charge that is reliable for function then manipulate the old for function. It’s surprising what a .1 grain change can do.

Often you can get the information from the manufacturer.

Here is a good resource.

Either an alignment problem of the suppressor on the barrel, or inside the suppressor. Most likely a baffle strike. Holes in the target are most likely not round.

Question for you guys, I have found an accurate load for my 10.5" pistol, but it is only 1720 fps. Do you think the bullet will perform at that speed inside of 100 yards? I really would like to use it for deer this year if I can. Greg Page 8 I dropped velocities, there is more info there about pene...
