Now I've a question for Sir Ron: From a longtime correspondent who wanted my opinion on how far he might go in using AA2230 behind a molly-coated 405gr in his Encore Prohunter in .45-90. COL is 3.30" and the chamber allows up to 3.55". So far he's gone to 70 grains without issues. He didn't give MV. I told him I'd ask the expert on the Campfire, as I've no experience with such a bullet.
So if you care to respond, it would be greatly appreciated. Thanks.

Sir Bob, Looking forward to that latest blog. Regarding the .45-90 TC Encore with 14" barrel and a muzzle brake, if he is doing well with 70 grains of AA-2230 at 3.30" COL, and could actually seat it out another 0.25" with that unspecified 405-gr with moly coating, he must have a bit of throat, more than usual on a .45-90 ?
That is a 2.4" case length and he would be hanging 1.15" of bullet length in front of the case mouth. That does not make sense with the usual cup & core 405-grainer being only about 1 inch long. I would tend to tell him to not go any higher in charge. Leave well enough alone.
Like you, I would want to know more specifics on the bullet and what velocity he is getting. Moly won't do much. Maybe his break-open action will handle about 50,000 psi with the .45-90, and he might be there with his 70 grains. Is his brass good stuff like Starline ? We are just whistling past the unknowns here.
