[QUOTE="Brent, post: 26808, member: 99"] Sheldon, I was getting 2780-2800 in my Ruger 338wm with the Federal TBBC HE loads. I loaded that HE brass up with 4831 or 4350 with 250gr Barnes X bullets for a MV of 3050 fps. Brass only lasted 4 loadings and was way over pressure I'm sure, but strange enough, I couldn't get over 2800 fps with the regular Federal brass no matter how much I stuffed in the case, Velocity actually "fell" 200 fps in a 1gr step up with the normal stuff. It never did with the HE brass, I just couldn't keep the case from bulging to get any more powder in there it was compressed so much. I actually had to take about 10-15 seconds to seat each bullet so it didn't bulge the case and/or push the bullet back out. When I was young and dumb of course. [img]images/icons/grin.gif[/img] My buddie Chuck that I'm heading to the range with in the morning, he has a 330 Ultra and can't get any more than 2830 fps on my Oehler with a 250 SGK using RL25, bolt lift just gets stiff on it. He's not too happy with its velocity to say the least. He wonders if he just has a slow bbl or something. We'll see what he's got cooked up for tomarrow and how it does. [/QUOTE]
