RRA .223 groups from today - what now?

[45ACPUSER]

OTM bullets are match bullets and are not a hunting bullet. If you want a test of the accuracy potential of your bbl then do that. Varget is the key with not TAC when testing the accuracy potential.

If you want a heavier bullet for varmints then Nosler makes a 60gr NBT and Hornady as a 60gr V-Max

Brass prep is key, too and doing it before shooting it the first time is always a good idea. Well, unless you buy Lapua.

Next when seating the bullet start seating the bullet the lower the ram and turn the case 180 degress to finish seating the bullet.

If by that you mean you will reduce the runnout of the bullet, it doesn't work. The problem with bullet runnout can only be solved by spending the $$ for a precision seating die. Redding, forster and RCBS sell competition seaters, I found the forster solved my runnout problems.

One thing not mentioned yet is the age of your barrel. I doubt it is ready yet to start producing super small groups. I would buy or load some blasting ammo, go out, shoot a couple hundred, clean the barrel, THEN get down testing groups.

I've never tried TAC, so I can't comment on it's accuracy potential. I've tried Varget, but find it lacking in most applications/bullet weights for my 1-9 bushy. My go-to powder is H-335. I also use a lot of surplus pull-down WC-844, it just plain works! Dealing with a buddies match barreled AR last summer, I came up with a great load using IMR 3031, Sierra 69 MK, and the rem 7.5 primers in lapua cases. Right at ½" groups @ 100.
