[QUOTE="NZ Longranger, post: 861715, member: 14"] Kirby, Some interesting comments there. We've been working with Rl33 a lot lately in 338Lapua improveds and have noticed the same thing now you mention it. The 250 and 300gn Elite Hunters with the Hybrid ogive shape that is usually quite setting depth forgiving have definitely shot worse as you seat them deeper. We have settled on a 5 thou jump for both and been getting good accuracy there. We haven't tried a just touch or jam though. The ES thing has been interesting. We got great ES's with the 250gn with 116 to 117gns at 3290fps, but have been struggling a little with the 300gn at 2990fps. They are shooting great accuracy wise, but the ES's are not what we're used to. Although we haven't noticed powder temperature sensitivity, we have noticed barrel temp is making quite a difference. The first shot down a ambient temp but well fouled barrel is always quite slow compared with follow up shots. More testing required to try and figure what's happening here. Greg [/QUOTE]
