[QUOTE="marc357, post: 2935063, member: 1786"] I'm sure you could get back to your happy place, but my guess is it would require re-working the load. I am shooting a rifle with a very long throat so I can seat the bullets farther out so I have room to cram more powder in there ;) A long time ago I had a custom Win Model 70 .300WinMag built. I cut the block out of the back of the magazine that limits cartridge length to SAAMI length of 3.340". Installed a modified bolt stop so the bolt would come farther back- far enough to strip a round from the magazine Then I determined the longest length I could seat the bullets and still have them feed and function. That ended up being about 3.520". I loaded a dummy round to that length and gave it to my gunsmith, he throated the rifle to accommodate this longer round. I am shooting a Hornady 208 gr bullet @ 3006 fps using H1000, it is still jumping at least .100"or .150", I don't remember. Accuracy is fantastic. I've never really chased the lands in any rifle, I just load to the longest length I can and tune the powder charge. [/QUOTE]
