[QUOTE="woodnut, post: 1554991, member: 17593"] Here's my 2 cents. I don't have much data; but I did do one on RL19 in my 6 CM. I know I'm not going to be shooting it in temps of 40*,so I found two days of 90 and 75 degrees. I have a starting load with the 108 ELDs that at 75 degrees had an SD of only 5.09 and ES of 10.84 and vel. avg. of 3061. At 90 degrees, the 105s (I didn't shoot, for some unknown reason, the 108s at 90) gave an ES of 27.65 and SD of 14.10 and vel. of 3166, a 105 fps diff. Yes, a big vel. diff.; but accuracy was well under 1/2 MOA for all. I figured to stop testing as that would be plenty good for prairie dogs and steel to 1000! I was having a very hard time finding H4350 and heard it was a hot burning powder anyways. I tried several other powders and RL 19 just seemed to be the slightly better choice for this 6 CM and my use. I also figured if it got hotter than 90, which it could in S.D., my starting load would still be safe. Hope I'm right! [/QUOTE]
