im actually going to start with 50s....
my rifle seemed to like 50s better than 55s...i shot 55s ALOT...(factory ammo though..)
i was in a jam and couldnt find the 55gr ballistic tips anywhere so had to order them...ghog huntin was at its prime...i NEEDED ammo...i bought a 40rd value pack of 50grJHP UMC junk...that is the ammo that shot sub-moa groups if you believe that....i couldnt...so i had to do it several more times lol...
so im going to start with 50gr NBTs....my buddy actually loaded for someone elses SPS like mine and it really liked Varget so i was going to start with it...i dont know hardly anything about powders....for the whelen i went with RE15 just because it seemed to be the most popular for it....
got to get my stuff in line for that soon...but i wont be shooting till its warmer out...no sense in workin up a load in the cold for a rifle that is shot in extreme heat....id imagine if i was real close to a max in the cold of winter, i could potentially blow up on a 90 degree day in August...and accuracy now is likely going to be different than it is when its warmer...so i wont mess around till the weather breaks...
