367/300 SuperSlug (BC= .33)
This is also an experimental caliber. It will be very useful as it betters the ballistics of the much loved 38-55 of yesteryear. The bore mikes .368 land-land, with a groove depth of .375. Twist is 1-14. Bullet is cast weighing 300 gr. at .368 diameter, then is sized to .367. It is accurate and hits hard with 80-90 grains Pyrodex P. It’s sure to be a good killer on deer sized game. Recoil is surprisingly mild. A similar combination was used by the White Muzzleloading target team to win the 2007 Manufacturer's Match with record score.
2007 that was along time ago... I was young then

And the team that White beat in that competition and set a new record was ?
Anybody know? I'll give you a clue. They are back in business.
As far as the 45 cal 1:20 twist. I don't know how well they shoot as I haven't had time to do much lately but my Doc built .451 has a 1:20 twist.
He recommends 460 to 530 gr conicals. Most long Range muzzys have a 1:18 twist, such as the Gibbs etc. so I have a hard time accepting that the 1:20 twist would be to fast. harder to work up the best load ,yes, to fast no

Knights own 45cal target rifle model DE658B was a 1-18 twist 28" barrel Extreme. It won for several years if not all years between 2001-2006? Its in the Knight 2006 catalog.
Nearly all the of the Savage and Remington replacement SML barrels PacNor/Krieger/McGowen/Brux/ect are from 1-18 to 1-22 twist and shoot 40-200gr bullets in sabots with amazing accuracy even at 300 yards or beyond. We are talking about a saboted bullet moving upto 3000fps and 35k psi or more.
These are highend barrels with a good history of proven excellent accuracy. Add in the sabotless applications also and the sky is the limit. Busta was shooting the 250gr SST sabotless/BH209 in a 1-20 at speeds (2300fps) exceeding most 50cals and doing it VERY accurately. Sabotless isn't for everyone but its not that hard with 1-3 sizing dies and 2 files.
IMO a fast twist 45 has serious potential to get costs down with conicals or sabotless without sacrificing good sabot accuracy too. Just don't expect a 155gr bullet to shoot accurately at 2500fps with 3 Pyro pellets. Personally i want a custom 1-24 twist 45cal or a gain twist barrel ending in 1-18 but those are SUPER expensive to make. Just the straight 1-24 twist is going to cost me an additional $150 from Pacnor vs their standard 1-22 twist.

When Knight won the competition they were shooting conical bullets too. I had never seen the target rifle you are referring to. I wonder how many of them are out there.
Could you scan a a pic of that rifle from their catalog?

Sure, here is the pdf file. The pic is the top right under the shooting team. They must be super rare because i can only find one and it belongs to a Knight employee. Ive been trying to talk him out of it or a 1-20 for a affordable price.
