This is a bit deceptive, because the groups on either side of this one weren't in any sort of graduation from good to bad. (I'm attributing it to using virgin Nosler brass) I had already found my powder/velocity node, and this was a session of seating depth testing.

I understand that. What part part of FL sizing .005 is beyond tolerance? What is spec? You didn't answer my question.

Seriously. I'd love for someone to answer this. It's standard practice to bump shoulders back. 002 +/-, and that's only at 1 end of the case. By FL sizing a cylinder (cartridge case) .005 you are only moving the brass, in any one location,.0025. Thats a whopping difference of a half a thousands...

Other than not liking what your micrometer is saying, are you having any adverse effects? If you are reducing the overall OD .005. That means you're only moving each part of the wall in .0025. I'm not seeing a detrimental issue worth spending time and money on.

C'mom, somebody's got to bite...

My 280ai program is the same way. Other than having to put more pressure on the press handle than I'd like, I haven't seen any detrimental effects. I try for a .002 shoulder bump. Measuring diameter of fired vs diameter of sized, with the greatest variance being .005 at the base of the case...

My experience is, that cartridge is worth any minor inconvenience that may come with it.

I'm way up in the northern plains (far enough that if the wind switched direction I'd end up in Canada), so I'm not in the position to entertain the deal. But... You're a great American Nubba. May you and your household have a new year full of grace and prosperity.

Let me see what I've got on hand. I'm about 4 hours from Colstrip.

I haven't seen any RL26 around here for quite a while. I've got a little RL23 and IMR 7828SSC, and a fair amount of H4831SC. I think I should be able to find a recipe using one of those. I started out with RL22 and got good MV w/o pressure signs. But that was before I figured out that it was...

Thank you for the feedback. I've got plenty of other variables to sort out, but I had been wondering about this and figured I'd ask.

Lol. I figured that'd be a topic that had been covered; just not covered to death. I'll do some digging through the threads. Thank you for the response.

I started out with Fed 210 primers. But what do you guys recommend for primers for the 280 ai? Will mag primers be and improvement with a slower powder like H4831sc?

Should have my homemade annealing machine put together tomorrow. Neck sizing mandrels will arrive in a few days. I think neck tension has been a stumbling point for my grouping. So I'm going to cure that. What do you guys usually start with; seating depth or powder charge? I did a ladder test a...
