The Hidden Mistake Costing You Accuracy

So, um, whenever we get up to run a batch of seating stems at Forester Products, we really try to look at what, what everything, you know, what issues have we had, what, uh, what's working well, what's not.

And, um, w- with one of our last bigger design changes of the seating stems, we, um...

The older seating stems, and we've talked about this before, but always had, like, a really slow taper that we'd always kind of adjust to try to accommodate the different bullets on the market.

But what would happen then, being that we're constrained by that tight tolerance bullet channels, it would get really thin out at the end of the stem.

So if you had a bullet that happened to hit the very end of the stem, that stem would flare out, bind in the, in the bullet channel.

And I can guarantee if I was running an older stem on one of the burgers that I was doing with the pressure it was taking to seat, it would've, that older stem would've flared, for sure.

Um, but with our, our more, our latest design, rather than it, it, uh, flaring that stem, putting the pressure at the stem, it kinda puts the pressure back to the bullet.

So that's where when you have, like, a softer jacketed bullet, you'll start, and you have then that increased pressure, you'll start to see that potentially dent, indent the bullet.

Um, so, you know, a test you had done, uh, for us with the, using the AMP seater to measure that pressure it takes to seat, we found that different bullets, different jackets take different pressure to seat.

And it was kind of, I mean, I don't know, one of those things that, that you kind of know inherently to a degree, but it was pretty eye-opening really to actually push the numbers-

Mm-hmm

... to it.

Maybe you wanna just briefly talk to what that test-

Yeah

... how we did that test.

Basically the, we, we prepped the brass the same exact way for all, all the samples, and then, uh, we just took different bullets and seated them with the AMP press and just read how much force it took to seat the bullet.

And surprisingly some were, you know, around that 50, 60 pounds, which is where I usually like to see or what I s- what I see, not saying I like to see, but, uh, so-

But it's not something you're watching the whole time-

Yeah

... every, every-

No, and I, I'm not saying I'm loading all my ammo on, on AMP either.

Right.

But I, I have tested, like, with my process and then seating, and I'm around that 50, 60 pound, give or take, uh, threshold there.

Yep.

So then another bullet was, like, 80 to 90 pounds.
