Thickness of Newer Lots Of Lapua 220 Russian Brass vs Older Lots.

Asking a super competitive winning shooter exactly how he makes his ammo & how he makes his final decisions of when to, or not to shoot, I think is kin' to asking for my Grandmothers German potato salad recipe.......

I think you all are over thinking this.

There is a very good possibility that all Bart is doing is necking up the 220 Russian, doing the usual prep work, fire forming the cases to make it into a 6PPC, and sorting them by velocity.

Those not involved in Benchrest tend to think there are some deep dark secrets that are Hidden in the minds of only a few. Many shooters cultivate this myth.

But the truth is, it’s about good barrels, good bullets, and good tuning. And of course, having the skill to take advantage of these three.

Sounds simple. But just think about everything involved in finding good barrels, making good bullets, and maintaining a competitive tune.

I agree 100% Jackie! And on a side note I believe Bart only sorts brass by velocity for long range.......not srbr. I could be wrong, but that's the way I understand it.

I’m an open book!

But I’ve had Christmas House guests for the last week, and trying to keep things from freezing up. Found this post last night. I’ll try and measure some of my ammo today. But I had a 2am wake up and a two hour drive to the airport for a 5am check in.

Granny must of talked somewhere along the way as I know how to make that tater salad without looking at a recipe.

The only sport where your competitor will try to help you win!! Well played sir! I've had so much help from the shooting community it's unreal.

 

[Bronsin]

Even if it's just a skim cut to true them up, I'm turning cases no matter what.

You are wrong about the only sport. Rodeo cowboys take it to an extreme!. Roger Schuppe

@jackieschmidt OK! On one set of brass my loaded rounds run about are .2702. On the other that I’m using is .2710. My bullets are on the skinny side .2431 to .2432

Been there. Done that. Especially with broncs and bulls.

Your no turn neck is? And is that the reamer spec or is that what it actually measures?

Starrett micrometer or it could be a Mitutoyo, you know the cheap stuff

Reamer is a .273 neck reamer spec.

 

[D Coots]

Reamer is a .273 neck reamer spec.

Thanks, but do you know what the chamber actually measures? You know how things go sometimes. Most likely more clearance than what reamer is? Maybe.I don't know what mine measure either. Just curious if you knew.

Let's go back to if a bullet slips into a fired case. It's a good check. And nope, I've never seen a reamer cut exact dimensions. Some of that can be in the reamer some the steel itself and of course, the setup. Everything has tolerances, though. And I agree with you but I've never seen a reamer cut smaller than itself. The bullet slipping through the neck is a pretty good check, imo.
