He sent me a like new 1/20 twist SS 45cal Knight barrel to use for testing. I'm hoping to prove to Knight Rifles how important a faster twist 45cal will be. I hope it will shoot a wide variety of bullets really well.

I also have Lehigh making a really high BC bullet to fit the 1/20 twist barrel. I'm hoping it will be at least 230grns. I think that will make an awesome 40cal bullet. We will also test some sabotless as well.

Thanks to sqezer i will be shooting a lot this winter. I actually need to get some pictures up of this later.

I knew it was coming, you couldn't hold out too long without a knight and lehigh, thread!!!

Had to be a reason to so many threads tonight!

Why is it that they need so much convincing on this Grouse? The 1 in 20 seems to be a proven twist.
Anyway, Good Luck in convincing them, I would like to see them produce this rifle as well.

I don't get this? You have a Knight barrel to test to show Knight they need a Knight barrel?

I would buy a 1 in 20 45 Knight also. Looking forward to the test results.

I'm not actually convinced myself. When the 1/20 twist Knight first came out it failed drastically. My opinion is because of the weaker formulation of sabots. Now i think both MMP and Harvester have made great strides in making sabots better in all twists. Now we will see how well they do with a wide variety of bullets in the 1/20 twist at a wide variety of velocities as well. Lehigh, Barnes, Hornady to name a few need to shoot well to proceed i think.

In my opinion only, and no testing to back it up. I would think a 1/24 twist might just be the cats meow in a 45cal ML. Time will tell that's for sure.

should be interesting results. happy shooting.

The old 45 caliber mk 85s were the 1 in 24 twist. I like the 1 in 20 twist in my Whites but that is with conicals in the 450 to 500 grain range. I kind of thought those brass LeHighs would be long enough to shoot well in the 1 in 20 twist.

They are, but is the sabot going to be consistently good enough? And you also need to be able to shoot the 195grn Barnes and 200grn Shockwaves as well. I don't think a bullet specific ML would be a good idea right now.

Thats pretty much what i think too for a mass production. It will handle a good variety well and some loads extremely well, such as a 40-230gr SST or a Barnes type 40 in about 220gr. (if they made them) Brass is going to be even harder to get the weight up and get them to fit a current sabots.

Mainly for shooting 250-325gr sabotless a 1-20 or even a 1-18 wins hands down. Knights 2006 45cal target rifle was a 1-18 conical shooter. Gordy should have one of those BTW.

Most guys go with the 1-22 so they can shoot sabots and upto 300gr sabotless. Pacnor, Douglas, Brux and Mcgowen all offer them in 1-22 as well as other twists. The 1-22 is by far the most popular with the current 40cal bullets but 1-24 would shoot them fine. Knight MK85 45cals were 1-24. If you REALLY want a sabot shooter, they need a new sabots/bullets to take full advantage. Current 45x40 sabots are too short to easily handle a monolithic bullet over 230gr IMO. Ive seen the new 237gr copper and the ogive is extremely long to achieve the high BC. Jacketed bullets you can probably get upto 240gr without much trouble.

The White Power Star sabots would be awesome if you can find out who made them but it uses a 40-350gr BT IIRC. You wont get the fps that most people will want from a 45 even though those are deadly.

Good luck. A 1-24 45cal i would buy and probably will from one of the custom barrel makers if Knight doesn't soon.
