Semi - I would think that a 1:24 to 1:30 would work. I often thought of trying .451 bullets out of my GM LRH 45 barrel. Trouble is buying store bought they are probably cast too hard. And I don't want to get a mould just to see if they shoot.

Doc White is a true gentleman. Yesterday I sent him an e-mail posing the question. He replied this morning.
Here's his reply.
Here's his reply.
LAND TO LAND SHOULD BE .430, GROOVES .035 DEEP, NO DEEPER THAN .040, TWIST

I had thought about going with the .45s for my little project. But the heaviest .452 is 230 grains and has a round nose profile, which is not what I want. The .454/255 grain flat point looks pretty darn good, but I decided to go with the .430 because it would give me the option of both a Semi Wad Cutter or SWC Hollow Point in 240 grain.

Semi, I think that you are off one decimal place with the .035" groove depth. I am quite sure it should be .0035". I was off .0005" earlier when you asked the groove depth and I said I thought it was .003".

Don't want to squabble at all Semi, but Doc may have made a typo. I know Knight rifles have a depth of groove of .005 to .006 and Doc's rifles have shallower grooves. Even deep grooved round ball shooting barrels have grooves that are only around .010.

Not squabbling at all. I think you're right. Actually, I was surprised he recommended .430 land to land for the .429 bullet. I expected .429 or even something like .425.
(OOPS. Brain out of gear when I posted the above. The bullets are .430, not .429. Doc's recommendation would be an exact fit.)

Here is a link to something doc wrote. I find it very informative.
