The issue is the brass is too close in size to the SAAMI chamber at the base dimension. When you fire it, it can't really expand because it fits so tight. Then when you size the brass the die doesn't do anything because the brass didn't change dimension much at the base. If you make the die...

The looser body dimensions prevent issues down the road when you have 3, 4, 5+ firings on the brass. The SAAMI brass, dies, and reamers are too closely dimensioned and cause “clickers” after a few reloads. The brass being sized .001-.002 more isn’t going to affect groups, tight brass in a...

Those are the freebore diameter specs. The larger diameter allows room for fouling and bullets that are larger than the nominal 0.284 (some are 0.2843-0.2845). There may be other benefits, but those are the two I know if. It doesn’t necessarily have anything to do with bullet weight. The...

Depends on where the action’s threads start. If the threads aren’t indexed repeatedly during manufacturing of the action, then the barrel engraving won’t line up in the same place on every action. Or the barrel maker isn’t repeatably indexing the engraving on the barrel.

Here's my opinion on this. Hornady acts like 1/4 MOA rifles don't exist. Go to a benchrest match and see for yourself how the loading and tuning is done and the groups that are shot all weekend long. Then go to the next match and the same guys are shooting at the top, it ain't random. If you...

One thing to note, the faster powders being used in the 7-6.5 PRCW and velocities in that neighborhood are with 30-32” barrels. Drop that back to 22-26” barrels used in hunting rifles, you’ll be in the 2750-2850 range more than likely. F-Class shooters will pick the most accurate and consistent...

I’m not a powder expert, but high energy powders tend to have more nitroglycerine in them that increases their “energy” and they also tend to burn at higher temperatures. The downside is often less barrel life because of the higher temps and more energy content. I can’t say for certain why...

Just for clarification, that’s not a Lone Peak action

N570 is a very high energy double base powder. Retumbo is a single base powder and isn’t considered “high energy”. RL26 is another high energy powder that delivers more speed than others in the same burn rate.

There's a lot of good information in here! I'll put my 2 cents in. We build a fair amount of lightweight custom rifles at Pierce Engineering, and we build way more actions for customers who are building lightweight rifles. A lot of things depend on your budget, and the type of game you plan to...

The advantage of my design is the reamer shank is held directly by the reamer holder, and not a separate holder that then goes into the reamer holder. There's no possibility of tolerance stacking with the reamer being held by a separate piece vs being held directly by the reamer holder. Also...

I've gotten some interest in these and I'm planning to make a run of them. I'm thinking I'll start out around $125 for the reamer stop. The other popular adjustable reamer stop available is $225, but it's more pieces than mine. Thoughts?

I wanted to start this thread to share with you all the adjustable reamer stop I made. This whole project began when I was considering my options for how to control the depth of my reamer on my lathe. My lathe doesn't have .001 graduations on the tailstock, and my tailstock is round so attaching...

Sounds like you’re getting things figured out!

You can measure the distance the headspace gauge is protruding before reaming and while you ream. That however requires you have a depth micrometer and know how to use a depth mic correctly.
