Last post about this rifle was about needing BBL channel opened up a bit more. Its been done problem fixed. With a warm bbl I was able to hit a 32 oz Gatorade bottle at 610 yards. Rifle is semi custom 7mm WSM shooting 162 gr A-Max . Shooting at a 12 oz empty soda can at 465 yards bullet of course went through it but with out knocking can over. Amazing !
