mel Wrote:factory hornaday black eld-m chrono'ed slightly over 2600fps out of my gun , everyone of of the 4895 loads ive tried have shot about 100-125fps over expected velocity's , same with hornaday sst's and one other box of factory ammo ive tried
could be because im 6,000 ft above sea level maybe ?
didnt do a ladder test just loaded up the 3 different charge weights to try
i am pretty dang happy with the 28.6 load i can play with a few tenths down from there and see what it does maybe see what 28.3 does since i know 28.0 isnt as accurate
im also .010 under data's oal so i can move that to 2.260 and see what that does
Not sure. Something ain't sounding right. You sure your chrongraph is working correctly?
All of those speeds are way out of line of what's typical for a 20 inch barrel.
