I sure cant complain about the 1/24 twist in my White rifle.

The problem with the .45 cal, 1:20 wasn't the rifle. it was the lack of saboted bullets on the market. it's still a problem and the .45 cal 1:24 would shoot a far wider variety of bullets, that are already available. as far as conicals go, flounder is spot on .45 cal 1:20 with the conicals he mentioned are deadly accurate.My.50 cal knight is a kick to shoot full bore lead from and extremely accurate to boot.IMHO, the 1:20 would be a mistake to mass produce again.

+1 for a 1/24" twist. I think it is going to shoot a wider varied of bullets well, but good luck testing the 1/20 Knight- it will be interesting, if nothing else

I agree, if you do the numbers to have any bullet choice you would have to come up with sabots for everything from a 38 on up. The 1-24 is the practical answer.

I look forward to seeing the results. .45s have always intrigued me but I've never made the plunge.

Lee , it's a shame more bullets company's haven't made more M/L specific bullets.

The worst problem around here in the .45's is that no one carries and bullets at all for them. Powerbelts and that is it. I was going to order some Lehighs for my new .45 from Lehigh and couldn't never get in on there site?

The biggest problem with .45's really is bullet selection. There just isn't enough. There are only 2 (200gr sst and 195gr bx) that are made for muzzleloaders and the velocities they shoot. I know people shoot the 200gr xtp with some success, but I have heard too many reports of it being fragile for me to risk it. There is also PR bullets, but expensive lead bullets aren't apealling to me not to mention their velocity limitations. I read a thread where 180gr gold dots where coming apart at 10mm speeds...... The .45 market is a niche within a niche so I don't really see manufactures spending a lot of time and money to develop more options.. I think if they could get the twist rate and sabots right to shoot .375 rifle bullets they would be on to something though.

Grouse thanks for taking the time to do the testing. I did get out last Wednesday with 3 generations of .45's, The SS .45 DISC I got from you, a NIB .45 ELITE, and my old go to ORIGANAL .45 1-20, all 3 had the LEIGH CONVERSIONS. The Disc & Elite were spottless in the plug & bolt area. The 1-20 was another story, lots of blow by in the plug & bolt area. The HEAD Space must be differnt, I know this is something Leigh & Knight will be able to work out. I was shooting 70 grs. by weight of BH-209, blue harvester sabots & 40x200 XTP's at 50 yds, they were printing almost 1 hole groups. THANKS.

also, when bh209 came out people were saying that it was going to revive the .45 market. I think that the opposite is true; being pogressive, it shoots heavy bullets well enough to close the trajectory difference between the two. Granted, all of my info is second or third hand, but I read a report where a .50 shooting a 245gr barnes was averaging 2100fps, whereas a .45 shooting a 200gr sst was getting 2200fps. Based on those numbers, the difference in drop at 200 yards was only about an inch, but the .50 had considerably more power. I like the idea of a .45 though. I really think the best thing for .45's would be to get it into an existing bullet range (hopefully rifle) by chaning the twist and sabots available
