I run 51.0 grains of RL 22 with a Fed 210GM primer and the 115 Bergers jammed in a 30 inch barrel. The load is very hot and cannot be used in hot weather. You may not be able to get tht high in powder load. It is just death and destruction on antelope at long range. Of course antelope hunting
is not high volume shooting so the barrel seldom is allowed to get hot. The chamber is "minimum SAAMI" so it is tight and the action has been trued.
