So I know she’s not a Percision round. But I love shooting her. The question is what loads has anyone worked up.

I have been waiting on a cheapish barrel to show up somewhere so I can chamber a bolt gun in the caliber. I will probably use magnum brass instead of the rebated rim brass. I picked up a brand new reamer for $60. Nothing like spending a hundreds to justify not loosing $60.

I did these with a 16” barrel. I later cut it down to 9.5” and changed the gas system which led the tuning some loads that are just written on boxes. I have dummy rounds for depth, but was pretty much focusing on mag length.
Teppo Jutsu has the starting data most people source. I like the RL7, it can do sub blackout and regular 223 also.

I had a great deal of success with the following load. Good 1 in to 1 1/2 group at 50 yds. A few strings holes touching.

Berry 350gn plated bullet
28gn Lil Gun
AOL 1.95
Have not Kronoed this load yet. Of all the loads I have tried for the Berry 350 gn this is the best. H 110 will be my next test load, I discovered AOL is very important for my Hardend Arms Upper. My gun did not like a AOL 1.97

Been busy, still haven’t worked up a load for mine. I’ve had real good results with Steinel Ammo though...

only thing I’d say is watch what brand bolt you use with the cheaper barrel. I tried mixing a tromix barrel and a Wilson combat bolt face and I couldn’t chamber a round. Switched to all tromix and it works like a champ. I hear there are a few different specs for the reamer, some are apparently “reverse engineered”...
