[QUOTE="Wild_Bill, post: 183912, member: 4785"] [b]Barrel[/b] Hi I think you should be careful with the 3 grove pac nor brl. the lands are usualy wide and they can have a tendency to scolope out on the top and look like large dishes on them this allows gas to get past the projectiles as they are going down the bore. Also the 3 grove might be hard on thin jacketed projectiles like Bergers and A Max's. Hope it works for you but don't get the barrel to hot. Also be carefull as sometimes the pac nor barrels are not as hard as other brands so run it in well to work harden the bore and the heat from firing it will also heat treat the bore. Cheers Bill Australia [/QUOTE]
