[QUOTE="Outlaw6.0, post: 930473, member: 23486"] I haven't had that issue. One theory I've heard is that RL-17 doesn't tend to show signs of pressure until you're quite a bit over max which makes the temp swings even more pronounced. I've been using RL-17 in a Lazz Patriot (short mag) for years under the 168TTSX @ ~3400fps. If you're seeing huge temp swings i'd recommend First a primer test to see if you can lower your ES then back the powder charge down a bit & see what happens. You may also try a standard primer instead of the magnum, John Lazzeroni actually recommended I switch from the 215M to the 210M in my Lazz'... I almost fell off my chair but i'm giving it a try with a 190vld & RL-17 Ladder test in the near future. I'm starting to believe more & more that temp stability is a more of a scapegoat than it should be. I'm finding that an optimal charge weight, primer & OAL combo have far more to do with it than Powder brand (I could be wrong, god knows it wouldn't be the first time :rolleyes:). I actually just read a report where the vaunted H4350 was swinging somewhere betwene 50-80fps in a 6.5 'creed over a range of temps.... makes you think doesn't it? :cool: With my minor experience with the short mags & RL-17 (in 30cal anyway) shows that it produces a LOT more velocity than standard powder making the the WSM a true equivelant to the 300win mag. It may not work for everyone but if you suffer from tinkeritis as bad as I do, a couple tests never hurt :D. t [/QUOTE]
