[QUOTE="elkaholic, post: 1197355, member: 13833"] After reading "Thederksters" post on the 195's in the 7SS, I had to go out and buy some to see how my numbers compared. It turns out that they compare pretty well. I first tried to see if I could get enough RL33 in the case to max it out pressure wise. I could only get 66 tightly compressed grains in which was pushing some of the bullets out so the coal was VARIABLE:D The load shot very well considering, but was short of max by quite a bit based on primer comparison and bolt lift. I then tried RL26 to compare to Derksters data. He has a 28" barrel and mine is only a 26", so I expected about a 40' difference if loaded grain for grain. I did load one grain more than he did which should have added 50'. It turned out that the data compared quite well given different rifles. My barrel is a 5r Krieger #4 in a 9 twist. Berger recommends an 8 twist but I am shooting at 4250' elev. Below are the results. I think with a little load development, these 195's are going to be a hammer! Bear in mind that this case only holds about 72-73 grains of water. I was shooting in a 25mph wind at 100 yards (mostly tail wind) ......Rich CAN ANYONE SAY "F-CLASS" [ATTACH]60756.vB[/ATTACH] [ATTACH]60757.vB[/ATTACH] [ATTACH]60758.vB[/ATTACH] [ATTACH]60759.vB[/ATTACH] [/QUOTE]
