ar10 creedmore coal questions

[rockwind1]

so factory ammo appears to fit fine in my magpul magazine, but after checking with my hornady modified case with a 140 hybrid, if i wanted to seat my bullet anywhere near the lands, it will not fit in magazine.

does anyone else have to have a pretty significant jump to keep handloaded ammo within mag specs?

thanks

Not uncommon. Buy different mags that allow longer COAL or use a jump tolerant bullet. I've got quite a few very accurate loads that sit between 2.78 and 2.82. Bergers and ELDM's 140's in both and 147's in the ELD at 2.81. Fits a pmag fine.

I assume that most ARs will be limited by ar mag lengths.

6.5cm gassers have zero issues getting to the lands within mag length. You should be hitting lands in the 2.835-2.855 range.

Your issue is you're using Magpul mags. Trash them and get some ASC SS, KAC or Larue mags which load to 2.865-2.871".
