Re: How to over come overbore?
My limited experence has led me to beleve that slower burn rate powder will work.Example 7mm rem. mag clasic load of 79.5 gr of H870 produces 3100 fps in a 26"barrel,Ruger#1 Accuracy is 1 moa. Another of my experements with a 300 win mag using a surplus powder that was only available hehe in Utah. Ireco 85 Ball powder very slow burn, 84gr behind a 180gr Sierra game king,Fed215 primer,velocity 3200fps 5/8" group 5 shot @100 yds. This is out of a Browning Stainless with the Boss system.This load was pressure tested at Barnes an was at 59100 psi, sammi max is listed at64000psi. With a 300yd zero the drop is -8"@ 400yds. Energy figures to be over 4000 ft lbs more than my .338 win.I found that a premimum bullet would be a better choice fo elk. [img]/ubbthreads/images/graemlins/cool.gif[/img]
