Home Forums Hunting & Shooting AR and Tactical Rifles My brother ordered his first AR, looking for reloading resources

Hmm well maybe I'll try when I do some load development. Orange dot targets or some other targets are ok?

Well I'll just leave it at this.. I've loaded a couple rounds or maybe a few ten thousand more than that on a 550 with Varget and RL15 and TAC over some years. Never saw a weird shot of any of those rounds really that I couldn't blame me on,. Granted high-power matches, not BR, but IIRC I did have the bars amended and did jiggle the press, plus a powder check system accounted for anything WAY out of line...

That said, and not knowing the new powders, TAC wouldn't be bad substitute IMHO.

you might be reading the irons part about reduced 600 yard targets, that means a 600 yard target scaled down in size to be shot at 100 yards instead and supposed to represent the difficulty of 600. Which it doesn't come close to IMHO, but you do have to shoot fairly snug groups. Might even have to shoot a tighter group at 100 than 600 to stay in the 10/x ring but the wind isn't nearly a factor at 100 like 600.

That said if you can produce a pair of 10 shot .25 MOA targets my hats off to you.

I"ve shot some snug groups that impressed me, but mostly luck really in many ways, all they way to 1800 some odd yards. But repeating them has been extremely tough... 3 shot groups at 1800 something on the order of about 8 inches with a rough tape measure... and 5 shot groups at 600 yards on the order of 1 inch or so. But I can't do it consistently

How did you get RL15 to work in the 550 powder measure? Or did you use a different powder measure mounted to the 550? I've used a Uniflow for stick powders like RL15 on mine, but no way will my Dillon powder dispenser work with it. It doesn't have the leverage to cut powder kernels, which is what happens in a sliding bar type like that, so it just hangs up and stops.

TAC of course is easy and meters great all day long in the Dillon dispenser.

Well I chrono a load of 26.5gr leverevolution,cci 400, frontier brass, 77gr otm, shot a 5 shot .648 group. avg velocity 2814 fps, SD of 12.

I’m going to use this load for the nra mid/range prone competition shoot this coming week. Shooting out to 600yds.

Like to add shot a load of 26.2gr of leverevolution, cci400, frontier brass, 75gr hornady 6 shots held strong for .662 then got 4 flyers that opened her up. Anyhow avg velocity 2830 fps, SD of 20

No those groups I mentioned were 3 shot in a 100 yard underground lab. Let me clarify that it was not a 10 shot group and there was virtually no wind in my setting. I was using a M4 which I shot off some bags.
