[QUOTE="royinidaho, post: 1104170, member: 2011"] What are you that are shooting these cartridges using for a press? I'm using a RockChucker Supreme and it doesn't have enough umph to fill length resize. Either the handle is too short or the chamber is a bit big on the head end as compared to the dies, or there is something I don't know. I size the brass as much as I feel comfortable without tearing up the bench and sticking the case in the die... My spot of bother is that the resized cases chamber with bolt closing pressure. Enough to require increased bolt force to close. With these cases I also get the "bolt click" on lifting the bolt but no extraction resistance. On cases that chamber "properly" there is no bolt click. Which I like. I'm not loading hot. Though I seem to have. :roll eyes: Cases were originally fired with 142.5 gr Retumbo, 350 SMKs @ 3250 FPS MV. All shots left an extractor mark whose significance varied with the case. But they all had it and primer pocket expansion was quite noticeable. I'm shooting 377 CEBs ahead of 149.2 gr H-50-BMG and Fec 215s and Jamison cases. MV is only 3100. The leading edged of the "ring" is right at the case mouth. Primers are flat but not muffin rimmed (which is unusual for me..:roll eyes:) She shoots exceptionally well with this load Any hints: I'm thinking: More sturdy Press mount Longer press handle Polish head end of sizing die Get a 50 BMG press or Get some decent advice from you guys.:) [/QUOTE]
