So far I have tried:
110 Accubonds
H4831sc (range from 48.0-51.0)
Remington Brass
CCI .34 Primers
The results have not been favorible with the tightest group being 1.43" @ 100yds. Almost all 5 shot strings stack vertically but no two shots are touching. Stock is pillar bedded, Scope is nice and tight...
My first question to all of you on THR is...
What is causing the vertical strings? Could it simply be barrel heating (1 minute between shots fired)?
Second question is...
How can I cut down on copper fouling? After 3-5 shots the barrel is full of copper which takes me about an hour to scrub out with Sweets 7.62 and Hoppes. I have used Tubbs bore polishing kit and followed the directions included, however I havent experienced much improvement.
Components I have on hand and will try with some direction:
Bullets: 85 gr Nosler BTs, 100 gr Sierra SPs, 110 Nosler Accubonds
Powders: H380, RE 15, VV 540, IMR 4350, H4831sc, VV N160 and VV N560
Thank you all in advance for any advice and guidance.
