300 AAC Blackout-reloading data

[Chad C]

Tip #1: when shooting 300BO.....don't use 6.8 mags.

The load functioned fine.
17grs of 4227
COL- 2.060"
125gr Nosler Ballistic Tip

Indeed to chrono and shoot this round for accuracy.

Sweet!

I just picked up some RL7 and some 150gr bullets... Not sure how its going to work out, but it gives me something to play with. I'm shooting a bolt gun so I can pretty much do anything as long as it goes bang and stay within MOA I'm happy!

Anyone have feedback on the standard RCBS FL dies or the "tactical" flavor in the RCBS AR set ? From the little I've read the difference may be in the crimp....

I need to procure one or the other here pretty quick, having blackout barrel dropped into one of my Rock Rivers.

I've got the Lee set. Came with the rifle. I like Lee dies....that's about all I like from Lee.

I somehow formed a pattern of using Lee dies for pistol, RCBS for riffle. Nothing fancy, I'm a slow single stager!

[texag93]

If I'm buying dies, Lee for pistol, RCBS or Hornady for rifle.


I run Lee dies in my progressives for pistols.

Time to start playing! I got a mix of bullets, but dang powder is hard to find!!!! These range from 125gr to 220gr.

What bolt gun will you be using? I bought the rem 700 sps 300blkout last night for a birthday present to myself. Plan to do the paperwork for a suppressor this week and shoot supers out of it until the can comes in.

I'm using Alliant 300MP with my supers up to 140 grains.

I've tried H110, W296 and Lil Gun for subs with them not cycling even when running suppressed. This is on an 8" Noveske AR. Obviously if you are running a bolt gun that would be non issue.

Currently have some loads worked up with Accurate 1680 just waiting to get to the range or the lease to function test and chrono.

What all bullets are those? I recognize what looks to be the nosler BT and maybe a Barnes TACX. What else you have there? Im looking for more options for my supers.
