I've had great results first time around with 178Grn Amax and 63grns of H4350. Federal 215 primers if it makes a difference. I was getting .75 groups at about 100-125m.
Does anyone have any idea about how much punch I'm losing with a 20" barrel tikka battue vs the usual 24-26" barrels? Not that I'm going to switch rifles.... gotta love a 6lb gun firing 300wsm!
