Anyone here shoot Maxi-Balls? How do you like them? What are your results when hunting with them? I shoot some 615gr Maxi-Balls out of my 58cal. They are tight loading but I like them. Fun to shoot a big chunk of lead like that.

Also, anyone know where I can find a 58cal Mould for a Maxi-Ball?

I believe Lyman used to carry it possibly still does, NEI I believe lists it, Mountain Mould would make you one. I have shot the 440 grain LEE real out of my 58 works well. Use soft lead to cast if you get a source of lead. the metplat of both the Maxi, REAL, are very small! ( the MetPlat is the little flat end on both, the tapper doesn't get wet when they hit, so it need soft lead to flatten and work.)

Veral Smith of LBT has a very good design of connicle for smoke poles, do a search and write him a note and I believe he can make you a real thumper for the .58. Veral has an in-house, in-stock mold sale on rigth now and has a .50 connicle double cavity mold on the list.

" 213: .512 400 gr and 310 gr in 2 cavity mold. 50 cal muzzleloader bullets for use without sabots or
patches. Band at nose fills grooves, rest of bullet is .499 to slide freely down bore. Base upsets to seal and drive bullet if pure lead is used. Blunt nose, very deadly game bullets. "

I shot maxiballs out of my 45 and they shot OK but had much better accuracy with the 10mm 200 gr XTP and sabots. Out of my 50s I found that the Maxihunters shot better for me (275 gr) than the Maxiballs. This was out of the 1:40 and 1:28 barrels.
Because no one makes a Maxihunter mould, I've been shooting 320 gr REAL bullets out of my GPH flinter with very good results.

My old .50CVAStagHorn shoots the 370 grain Maxi-Ball very well. Have killed a few hogs it. They all diedswiftly. The powder is 100grains of Goex Pinnacle.

My Lyman .54 Greatplains shoots 430g maxi-balls way better than anything else I tried in it, and that's been most everything. The rifle is close to 20 years old, and has 1:48" twist as best I can tell. Ran into a guy at a gun shop last fall, he overheard I shot a .54, and said he had just bought a bunch of bullets at an auction with some other stuff, and didn't need these. I'mnow well stocked.
