For all intent and purpose that is correct, but other factors come into play.Debth of rifling, evenhow the rifling was made.

The 1-48 is a do all twist they used to say. They will shoot conicals well and roundball well. The 1-60 and slower are more at roundball but some people shoot minnie ball out of them as well. The 1-28 I found will shoot conicals and sabots but I think for all intent and purpose it was meant for sabot loads. I guess that would depend on the make of the barrel more then anything else. The 1-32 & 1-38 are more aimed at conicals I was told. Then you have a White Rifle with I believe 1-24 twist, yet they are a conical shooting master.

Really you never know what a rifle is going to like as a projectile until you get it on the range. Those broad guidelines I mentioned are only that, guidelines. You still have to push lead through the barrel to see what the rifle is going to do with it.Although with that 1-38 twist in that .54 caliber, I think you could and should have excellent luck with REALs, Great Plains, No Excuse, and Maxiball as well. As for maxihunter, never had any luck with them...

Thanks Cayugad. That is all helpful info. I think I'll get the barrel. I like the look and feel of the Scout but have not been realy happy with the 50 cal barrel. The previous owner damaged the bore so it has been tough to find a good load.

I have aSystem One with both 50 and 54 barrels both 1-38 twist,they both do well with round ball at 90 gr of P,the 50 shoots tight groups with 180 and 200 gr 44cal in sabots and 230 gr XTP with 150 RS and the 54 shoots tight groups with 270 and 300 gr Widner 50 cal pistol bullets with 140 gr of RS they will also shoot ballet maxie hunter and maxie ball. The limitation seems to start at 250gr XTP which it will shoot well but the 50 wont shoot 300gr or above. Hope this helps. Lee

For what it is worth, the best I can tell both my .50 and .54 Scouts have 1:20 twist barrels both were made in the years prior to the big fire. The .50 loves a heavy saboted round I have yet to shoot the .54 enough to know what it likes but it chucked a 430g maxiball down a 50yd range first time out with 2" groups.

Before you give up on your .50 Scout try some stiff loads with heavy conicals you may be plesently surprized with the results but a warning you shoulder will not be amused.
