[QUOTE="setandglass, post: 626523, member: 43653"] I dont have the magnaport no more. I had it cut off and a muzzle break put on thats why my barrel is like 25 inches. I shot retumbo powder today and 210 berger's 83,84 and 85 grains. Was shooting at 2500 elevation 32 deg. best average speed came from the 83. shot 4 shoots at 200 yards 3 of them would of been 1 Inch but i threw the fourth. Speeds stayed real close to 2814.(stayed within 8 fps of each other) Then went back reloaded same load 8 all together and shoot again. temp increased to 41. Well speed dropped to 2788 ish and speeds changed as much as 100fps with in these 8. Group size 6 inches. I have my bullets loaded long 3.685 could it be I'm out to far? I can't figure why the same load changes so much and gets inconsistent when it's only 10 deg warmer? its not the chrony because it does real good with the other gun. Speed can't be human. So whats the deal? [/QUOTE]
