Hello all. Great forum. I have been lurking for years and usually get my question answered through the search tool. My main muzzleloader is an ML2 in stock form except for a modified B&C stock. I've had it about 10 years and it has been great. That said, I am ready to tinker with it.
A Douglas #5 contour 1:14 twist .458" barrel made it onto my work bench.
For the guys that have used 1:14 twist barrels on their sabotless builds, are there any negatives to using one? I have seen a lot of discussion on what the optimum, or preferred twist is, but I can't find much info on using a 1:14 just because. The barrel was free so it is perfect fodder for tinkering.
My plan is to fit a Savage breech plug to it and fit it to my Savage ML2 action. Then make a swaging die and go burn some powder. My intention is to use smokeless in it at moderate charge weights. 2400-2500 fps is plenty for my needs.
What am I missing?
Thanks,
Jeremy

Free is always the best price  My personal feeling is that the faster TR will be fine, especially if you want to shoot the heavier 300gr+ high bc bullets. Way back when there was a theory that too fast a twist would cause sabot tearing and failure, so sw and others did a bunch of testing and it was shown not to be the case, sw even made the claim that based on his findings the faster the twist the easier it was to get a wide range of loads to shoot accurately. I have a douglas .50 that shoots lights out. If I had a concern with your plan it may be that #5 is a bit light in an SML, but if you keep the loads moderate and avoid a double load condition, I be you'll be fine. Best of luck. |

I used a long shank 5A on one of my guns. The 5 is a little short of shank and diameter for me but if you keep loads reasonable it will probably be fine. The 1-14" twist is a little fast too but won't cause any huge issues for what you want to do. It was free so give it a whirl.

Thanks, guys. I was wondering if the fast twist would have any negatives. Like bullets spinning apart after exiting the barrel.

With medium loads and the bullets we use sabotless, I highly doubt it. It should also shoot saboted .40s very well without issue.

I would put an Arrowhead plug it in also, smaller in diameter would help with the shank size. If it hasn't already been threaded.

Nope, not threaded for the plug yet. The Arrowhead also looks like it is easier to thread and install. I don't have to cut the inner shoulder, or relieve the lands for the vent liner extension on the Savage plug.
I like easier. Thanks for the suggestion. I have bought bullets from Luke before, but forgot that he has a custom plug.

For accuracy they say the slowest twist that will stabilize your bullet in all conditions. If you will always shoot a pistol bullet then 1:28 is most likely fine. I shoot bullets in sabots and 1:14 is not as fast as would like. 99 and 44/100 of all shooters will be fine with 1:24...( and it floats ) edge. |

But 1:24 barrels aren't free to me. 1:14 barrels in this case are. At least this one is.
I have looked at your posts on sabots. Very cool. Makes one think of all sorts of ways to get into trouble.
