Hey guys I have been sending alot of rounds downrange from my Defensive edge 338 RUM...I have a couple really good loads with RL22 and RL25..shooting the 225 gr accubond.1/2moa..Decided to change to H1000 and Retumbo for temp stability..wow best I can come up with is 1 inch groups at 100...tried increments in .5 grains...and several different seating depths... strange grouping..2 touching and 1 an inch away.atleast 10 different loads..all loads have the same pattern...tried the 250s...same thing...went back to rl 22 and bughole groups..same with Rl 25....I have a bunch of this powder and want to make it shoot...getting awesome ES of 8 and under and SD of 6 and under...very strange...I then loaded an accuracy load that Shawn Carlock sent with the gun..86 gr of H1000 300 smk...it shoot a bughole....loaded some 300 accubonds, they to were in one hole.....cant figure out why these powders wont shoot the lighter bullets out of this gun...I usually shoot the 225s as i am primarilyHunt highcountrty mule deer...any thoughts about why this is happening...best load has been 100 gr of h1000...fed 215 primer seated at 3.70 Oal...played and played with too many getting a little expensive...Shooting 96 gr of rl 25 consistantly .3 to .5 moa....Am I missing something, thanks guysgun)
