Good length for the magazine, cycled them through, they feed very well, but I noticed that I started loading at 36 grains of powder (the starting load was 38) sometimes, it sucks being dyslexic. Oh well, I can say that I was trying subsonic loads... :D

Dyslexics of the world, untie!

Those are some long, sleek bullets! Could be, that the length has reduced powder capacity enough that they might not be as mild as you think! Maybe...

Wouldn't seating them shallow in the case increase potential charge capacity...

I cant remember what COAL I loaded the Berger bullets that I loaded but I was able to run them at 44.5 of Varget and IMR 4064.

That's one idea I had, and I've also heard that they don't like to jump much. So I figured that I'd start at maximum magazine length, and work from there.

Mine from what just clicked in my head was loaded a little bigger than what my mag can fit in my SPS Tac.

With my AI setup I can set them waaaaayyyyyy out and not have any mag problems. Mine shoot awesome @ 2.805 though.

Maybe we are having a bit of a problem with terms. A given cartridge, bullet seated to a shorter COAL, will have less powder capacity than the same cartridge seated to a longer COAL. Less Capacity + same powder charge = higher pressure. That's why British DGR cartridges are so big, to reduce the pressure from cordite charges in tropical heat.

That's another reason why I seated them longer than the recipe called for. I was trying to eliminate pressure issues, as well as getting the best bullet performance. .0115 longer gave me just a little bit of room for the powder charge.

I've been using remington brass with fed 210m primers. My dad just gave me some lake city m118lr brass so I will be trying that as soon as I get my gun back from the smithy.
