I would stick to supersonic loads until you get the can.

Hodgdon 110 is a great powder for supersonic loads, but I would start at 17.0 grains or even i bit below and work your way up just to be safe; watch for signs of excess pressure.

It looks to me that the bullets are keyholing slightly, does anyone else see that?

All ARs leave dimples on cycled rounds. Its the nature of the beast. That is why you are supposed to use magnum primers in an AR platform. Please DO NOT spread this rumor here or anywhere else! A magnum primer is not recommended for anything but magnum loads due to the increase in pressure, and doe...

The 7.62SD is an excellent supressor! I purchased one last year. The newer .30 offerings are not only shorter and lighter but have more durable baffle stacks like the SDN6; all inconel. Also the QD mounting systems have improved, the newer mounts index much better than the older 18 tooth mounts. So ...

Sierra's test gun was a TC Contender if I am not mistaken, maybe that is why the pressure limit is high. What was Hodgdon's test gun in the manual you are referring to?

Is it still necessary (or advised) to FL resize it before the first load?

YEs, FL sizing is necessary on all virgin brass.

Ok, so riddle me this, NickelBrass. When I try to seat the bullet (M80) to the cannalure, once it gets there it wants to move freely in the case. Are you crimping the beejesus out of them to make them stay put? I thought I put a decent crimp on them with the FCD, but when I push the bullet downward...

ok...MOA is 1.047" at 100yards. 3.6" / 1.047. Gotcha

I was working with Nikon's Spot On program. Couldn't make it use the top portion of the reticle but I think this will work. I used the Hornady 225 Match with a BC of .670 and a MV of 1000fps. With a 200 yard zero it give 217 at the first dot, then 237, 256, 276 and 294 for the post. When I enter a ...

I also recommend the Lee Factory Crimp die. I am not a fan of Lee hardware in general, but the Factory Crimp die is good-to-go. I was surprised to read in the instructions that they said you could use it for bullets with or without a cannelure. I will have to try some with my Nosler 125 BT load and ...
