This rifle has been annoying to say the least.
Bullets it didn’t like at all Nosler 3030CTBT (150)
Hornady 3030 IL RN 150

Powders is didn’t like
Leverevoltion (sadness)
IMR4198
IMR4895

The first powder it liked was 32.5gn Varget,
Only with the Sierra Prohunter FN(3030 bullet) groups at 1.” Easily.

The Varget made me get out the burn rate charts and TAC is close to Varget burn Speed, and RL15 and Big Game are just a little slower. The XLR is. 24” barrel on a 3030, so thinking slower might be a good choice.

Todays loads are in.
Big Game, all powder charges produced under 1”
TAC also produced groups 1” or less at all powder charges

Finding the right powder and bullet is everything!

Starline brass WLR primers.

Happy New Year all!
