[QUOTE="morcey2, post: 956986, member: 71004"] It sounds to me like you're losing neck tension as you seat the bullets longer. That can cause the powder burn to be inconsistent, especially with ball powders. Since you're never going to get anywhere near the lands with that particular bullet, I'd just keep your OAL short and start experimenting with other powders. Either H- or IMR-4350 would have close to the same burn rate as H414, but they're a little easier to ignite. Or try IMR4064, my all time favorite for any of the 57mm long cases (7x57, 8x57, 257 Rob) even though it's a little fast for 6mm, it should work well with an 80 gr bullet. I think you misread his post. The SAAMI Max OAL is 2.825" and when he pushes the bullet out of the modified case to touch the lands, the OAL he would end up with is 3.382" with about 1/4" of air gap between the case and the base of the bullet as shown in his picture.
