I have a new box of Hornady SST 140gr and on a recommendation from the 1000yard guy at the gun store I picked up a box of match grade magnum primers.(Why didn't I think of that.) And I have a jug of 4831sc xtreem. I am pursuing a more accurate hunting load for my .264 win mag improved bench gun.
I'll start by just bumping the bullets up aginst the lands.Fill with a light load,fire 3 shots,chronograph,record group and conditions,check for pressure. Increase by 1 grain and repeat.Keep increasing untill I have pressure or the group falls apart.Once I find the best load I can pursue fine tuning with the seating depth or, if the best group is terrible I can abandon this combination all together.
Please feel free to offer opinions.I am trying to learn. AND I realize there may be more that one method which works.
Thanks.
