thank you!
about group size with different brass; it looks like that maybe Hornady was partialy right about their findings that accuracy is not very diffenent with different brand of brass...
probably on long range it is becoming more important to get more consistent brass because of small and large difference in velocity spread with inconsistent brass (in your findings that correlate with case head thickness ≈ weight ≈ internal volume), but in short range it realy doesnt matter for non-BR shooters...

Yes, agree. If you can’t get consistent brass then do what you can to make it that way - turn necks to uniform, uniform pockets, sort by case head thickness, etc.
Hi Bryan.
Yesterday I observerd funny thing with seating force when I was seating bullets.
I got smooth seating pressure when I was lubing inside the case necks, and I also got smooth seating pressure when I didn't applied lube to inside necks but when I only brushed case neck with dry brush or dry q-tip.
All bullets were lubed with Fluna Tec.
If I didn't brush or lube the necks, seating force was way bigger, even that I brushed necks months ago when I preping my brass.
Only if I brush neck prior to seating, I could lowered the seating force.
Do you have some experience with that, if I can skip lubing necks?

I found the same with brushing necks which is why I do it when I plan to complete my loading sequence within the next hour. As for the inside of necks when your bullet is already lubed, the additional benefit of lining the inside of the neck is a likely reduction in SD. If you need the smallest SD possible and need the most precision, then I’d line the inside of the neck too. If you are shooting well enough with what you’re doing now, then I don’t think it’s a big deal to lube inside the necks.
Hallo
I was always wondering about consistent champfering and deburring brass after trimmig. There are some tests on the internet, but not quite accurate. So if consistent champfering and deburring improves groups size for bench rest shooting...
Did you Bryan see and difference in groups between consistent champfer & deburr like with Giraud trimmer / Henderson trimmer / 3-way-head trimming versus champfer & deburr by hand with hand tools or with electronic prep centers RCBS, Lyman, Hornady...?
Sincerely

I wish I could afford those tools to test them all and compare them. I would definitely test them if the manufacturers sent them to me for testing but I’m not hopeful this would be the case…I’ve frankly never seen a shooting product scientifically evaluated with reference data provided by the manufacturer on their marketing website. In the shooting sports, seems like manufacturers can simply make the claim that their product is better or the best without showing any outcome data to support their assertion.
how do you chamfer and deburr your brass after trimming?
if you do this by hand, this is probably not so consistent than with fixed 3-way tool. but if you are still winning, than this can be the proof that ''consistent'' chamfer&deburr does not matter
