Rocky, when the weather this coming January is in the double digits below zero here in Michigan, Northern Texas is going to look mighty nice. If it weren't for work, school, kids, and church functions, I'd love to take you up on your offer. Forget betting for cokes, I'll buy the first two rounds.
And yes, I've worked up a 158 grain JHP load with WW 296 that works quite well. On another note, I was the one that worked up the chart showing velocities for the different barrel lengths for several calibers. That came about when a few folks were discussing shooting pistol calibers in lever guns. It was quite a while ago and I think it was posted in the General Discussions Forum. If you can't find it and you're still interested, email me directly and I'll see if I can dredge the info back up.
