[QUOTE="TwoMore, post: 1319830, member: 95166"] Thanx :) , we had some pretty nasty weather last night and some trees down so I wasn't able to get to the 600 yard targets but I did do some more 100 yard work, looks like it is going to settle in 94 to 95 grains of rl33. I really would like the brass to last a bit :cool: ,I did some pressure testing with 97 98 and 99 of rl33 ...97 went 3310 with a slight ejector mark no drag, 98 only 10 feet faster it went 3320 with a bit more mark, probably should have stopped there lol but the 99 went 3355 and I had to fistbump the bolt open and it gave that case a shiner and loose pocket. when I measured the 97 and 98 grainers the case grew at the back a tad and the primers seemed to go in a good bit easier when I checked them, so i just think 96 of rl33 will be the top of the load for that rifle. it was also 92 degrees today , my goal was 3225 -3250 with this build so I think I will stay with that and save brass :) [/QUOTE]
