In your guys expierence using Alliant Reloader 15....have you found "major" difference,s in burn rate from one lot to another? It's in my Big 3 (Varget, IMR-4895) for 308 and 223 with the heavies. You can have 'lot to lot' variations with any powder, but I think the knock on RL-15 is is it's a bit temp sensitive and perhaps 'dirty' for those who like to lick their muzzles after the barrel cools down. There was a minor scandal a few years back with some RL-15 being labeled 'Made in the USA' and 'Made in Sweden', but I'm not sure that that wasn't just a labeling mistake. Most were pissed with the 'Made in the USA' angle, FWIW, lol. I'm in Miami, so cold weather isn't a problem and I don't stick my tongue into the muzzle, so that's not a problem, either. Chris |

Chris That's a fact and is why one should always work up one's loads anytime you change lots of powder unless the load is well under the max. A few years ago I heard a lot of complaining about Varget varying considerably in burn rates between lots. It does happen with all of them to varying degrees. |
| I use it exclusivly for my .308 loads. It seems a bit faster than the Varget loads that I used with the same charge. I do not have a chrono but based on drop and mil adjustment the rl15 is shooting app. 200 fps faster than the similar Varget load. I dont mind though. Consistency is good. I am on my 5th or 6th pound of it and havent noticed anything different from lot to lot. I dont do anything extra to my brass for precision like neck turning etc. and I am averaging my 300 yard groups after overr 75 groups at 1.75 inches. I havent shot any further so I have no long range data. |

Ive been using varget for 15 or so yrs and have always seen variation,s in burn rate from lot to lot, but not as much with re-15. I was wondering if I wasnt the only one seeing this (for now) |

I was seeing borderline pierced primers with 77gnSMK/Nosler @ 24gn RL-15, lot# CE 0519 this summer when temps got above 95-96F it seems. Switched to Varget and no more soot in the primer dents no matter what the temps. Had a few matches this summer where it got over 100F in the shade.
Didn't have any primer issues with my 80SMK @ 24.1gn RL-15 though. (less bearing surface with this bullet than the 77's) and they grouped tight elevation @600yds. with only a 1/4 to 1/2min or so change probably due more to light conditions than temps as I could't see any pattern with moderate temp differences. |
