If I recall Berry's has a radius base, so just a little is required.
Bell / flare the case mouth enough that the bullet can start into the case. If you don't bell / flare the case mouth, you will shave some of the copper off the bullets. If you're lucky, you'll see the copper slivers. If unlucky, you'll get a copper sliver splinter under your skin. Been there, done that. Ouch!
You only “need” the amount that allows you to seat a bullet without messing it up. If that equals zero, you don’t need any.
flare the case mouth as much as needed to start the bullet straight and to not shave/scrape the bullet. The flare will be removed in the next step; crimping or as I like to describe it, "deflaring with a crimp die". Too much flare is when the case mouth scrapes the inside of the bullet seating die (or won't enter). I suggest it's better to get good shootable handloads now and worry about case life later. K.I.S.S....
Millions of rounds a year are loaded without any flare, most folks don’t flare rifle rounds at all.
Using GSI bullet feeders, that hold the bullet as it’s being seated this is how little flare I use with my coated (more delicate than Berry’s plated) bullets.
The seated bullet has yet to be crimped and the case behind it will have a bullet seated in it on the down stroke.
Using 9mm mixed brass and HAPs, my average flare is around 0.007". This results in a case gage failure rate of less than 1%.
Personally, I flare just a hair for jacketed pistol bullets, and most especially a little bit more for oversized plated and lead. IMO, there’s really no reason not to, and I find it makes bullet feed easier and straighter.
No, I don’t flare rifle at all.
That's a lot, by the way, but it makes seating smoother and I don't get any scraped or shaved bullets. I also don't get any cocked or crooked since I am starting seating by hand and pushing them in a good ways - 50-75 thousandths at least. I only use a single-stage press, never a progressive or automated press, so my answer will be different from the high-volume reloaders.
I do if I'm loading lead - includes coated or plated lead - even with gas checks.
What symptoms of "too much flare" are you experiencing? Too much is when the case won't enter the seating die...
Of course there is the “If it ain’t broke...” aspect of success.
I agree with Bill...
The M-type die seems to work better for loading plated and cast bullets for me.
