By shrouding the cutter with the shaft that holds it and controls the depth you will eventually plug up the cutter. If you have used a K&M tool you will see what i am referring to. I've done 2000 new Winchester cases with the K&M tool now. The first 1000 gave me sore fingers, but I chucked ...

I mic'd the cutter and it is 0.124 My drawing above shows a .064 diameter cutter with a 45 degree chamfering surface. I actually don't know what the .204 Ruger flash hole diameter is. I thought it was .060. It could be .082? What is it? The .168 body diameter above was to give a little wiggle room ...

I see the problem you run into with the 17 caliber cases. To get the tool through the case mouth, that only leaves you a surface of .040 to .050 to index on if you use the bottom of the case. That is with a 45 degree chamfer. I think it should work though. Please excuse my poor CAD skills. I've forg...

I want to say I'd rather have this tool index off the bottom of the case, but I don't know. Maybe there's a reason you chose to index off the case mouth. If it were called a "flash hole uniformer", it seems you wouldn't want to index off the case mouth, because you then depend on every cas...

It looks like the depth is set by the case mouth. Is that right?

Could the higher max charge with the heavier bullet indicate the 2 bullets are designed differently? Maybe a shorter bearing surface, or HP vs FMJ? Maybe the 55 is heavier, but it somehow creates less pressure?

I've had trouble with some fast burning powders in mine. Powders like Benchmark, H322, and Reloader-10x. The problem isn't that those powders aren't accurate in my AR, but that because they burn so fast, they're all spent by the time the bullet reaches the gas port in the barrel. This causes the bol...

I'm not sure my Dtech shoots any better than a factory DPMS, or enough better to justify the extra $800, but I did get exactly what I wanted. With everyone else suggesting customs, I figured I better give Mike some advertising here. I love the AR he built me. The only problem some have with Dtech is...

It may just be the light, but it looks like you can see a pretty good layer of copper at the muzzle. Near the throat may be even thicker. Do you clean for copper once in a while or only for carbon? Could try a copper solvent and see if that improves things. There's many brands of copper solvent, and...

When I discussed options with Mike Milli on my AR upper in .204 Ruger, all I knew about muzzle brakes was they are supposed to lower recoil, or keep the tip of the barrel from jumping as much or at all. I never considered they might make the report get reflected back to the shooter or bystanders. I ...

Congrats! Well written story. Thanks!

Too bad no CCI 450 magnums Yeah, I noticed that, but figured it might be of interest anyway. That pic of the flame coming out of the 7 1/2 sold me. I'd bet the 450 isn't that hot. I also wonder if it may not really matter what it looks like when it has plenty of oxygen to burn outside the case like...

It's not this one is it? http://www.amazon.com/Precision-Shootin ... ewpoints=1

Did you search the forum for "35 Berger"? I get 71+ pages of results. Search is in the upper right by FAQ. I only mentioned the search because I've posted this before. Try 27.8gr Ramshot TAC, a Rem 7 1/2 Primer, loaded to 2.247" max Cartridge OverAll Length (base to tip). Should proba...

I remembered reading a good article about primers that should cycle through here once in awhile. Here ya go in case you haven't seen it. Take particular note of how hot the Rem 7 1/2 primer looks in the pics , and the pressure standard deviation on the 7 1/2 in a chart towards the bottom. I've read ...
