Another notable, but should be obvious with the SD's Mark posted, the ammo shot sub moa. It also shot sub moa out of my SPR Reece ish guns. One has a Centurion barrel and one has a NOVESKE. Both 16 inch tubes.

I think my Noveske is so nasty dirty it took about 30 rounds burnt through it before the groups tightened up. It didn't shoot great, so I went back to our house load, shot like shit, .....asked Mark shoot it a while. Then at the end, it shot a nice sub moa group. Time to bore swab that bad boy.

I had to put some Springcos into a few of Pappabear's guns. I thought about throwing them out and subbing correct springs. ;)

Wow, that's bad but Pappabear has always been a bit more of a hippie than you... Are those the Sprinco springs that that "enabler" Iraqgunz gave you guys?

I only buy Colt springs. :happy:

Pappabear, did you get a chance to chrono it out of your 16" guns?

Have you guys had a chance to test any of the other popular faux MK262 loads? I was all about my Defender stuff but the velocities seem a little low compared to the real thing...

We are going to do that next just confirm data. But we did it on the first run of BH stuff and it was solid.
We will run 16, 14.5, 11.5, 10.3 and post.

We were thinking about doing them with and without cans.

All he would have done is put them in his guns. He loves my Sprincos , I saw his eyes when he looked at them. Can't fool a Pappabear.

We haven't. When you can load your own, it's not often that you buy very many factory loads. If I saw some of the options locally, I'd pick up a box or two to play with. Oddly enough.. I hate going into gun stores.

I did a little bit of thread surgery here. This thread has great potential, and I'd love to see it stay on track. Thank you.

I'd also be really interested on the data from various barrel lengths, both suppressed and unsuppressed.

Thanks. Yeah... I think Pappabear is bringing his chrono next time. My model of Magnetospeed won't work with suppressors.

I thought you guys had a Labradar too?
