I have a savage SA and I am planning to get a muzzleloader barrel barrel for it. My goal is to shoot .357 260gr accubonds from it. I want to use the dead center 45 to 357 sabots (its actually two sabots and the bullet) or I could go with one sabot. To stabilize the accubonds, I need to have at least 1:13 twist. I was thinking of going with 1:12 to be safe.
Anyone doing anything like this? I will be using BH209 to hunt (bc of the hunting regulations) but may play with smokeless too just for fun or if I move.
Will the sabots hold up to this fast of a twist? What velocity should I expect to see? I was guessing around 2,200 fps with BH209 which will give it plenty of velocity out to 700 yd for hunting deer.
I am planning a 28 to 30 in barrel (maybe a brux) and the action already sits in a XLR chassis and will sport a vortex red dot for hunting and my Leupold VX II w/ M1 turrets for load development.
Thanks for any input,

If you are set on that bullet why not build to shoot it sabotless? The sabot is the weak link, and in your case, possibly two weak links. If sabotless isn't possible or desirable personally I'd look at no more than one sabot used if possible. The more petal thickness between the bullet and bore, the more potential for problems.

State requires the use of a .40 cal for elk so I need to be able to use .40 cal bullets. It would be a little noticeable if my barrel was .357. I could go with a 40 cal to 357 but cannot locate any sabots.
The double sabots came from the idea of dead center bullets that use two (think they call it duplex). They are suppose to reduce he "thickness" and never used them so I am not sure if they actually work or just marketing. I have some with there crappy bullets and am trying to figure out if I can get just the smaller sabot w/out buying the bullets too. Which would be a 40 to .357 then I could go with a .40 cal barrel and use no sabot for elk.
Wish I could just do 357 just read the other thread and results seemed great so far.
Oh other option is to find high bc bullet in the .40 or larger but have not found anything worth looking at yet. Then I could go with a sabotless design and scrape the 357 idea. I would like to stay under 300 gr for bullet wait.

IMO, a sabot in a sabot out to 700 yards is asking for a lot!
Isn't the 260 grain accubond a 0.375 diameter?

I keep typing .357 whoops. Yes the .375 accubond. I am not planning to shot out to 700 yards on game 300 to 500 and is going to depend on how it works out.

That is a far poke with an Accubond at that velocity. Reliable expansion is advertised at 1800 fps but I'm sure you will get OK results a lot lower. I am thinking 1800 @ 250 yards max, 500 yards and you are under 1400. Plenty of energy but expansion may be iffy... assuming the boat tail matches the sabot OK.

I think success with the duplex sabot and PR bullet would be critical to using their bullet, which is soft lead and will easily deform and accept the spin. This would also seem to negate pushing it very hard but I have no experience at all with them, only a gut feeling.
The 240gr CEB V1 bullet that Steve and others here have had great success with sabotless has a calculated BC of a bit over .300. I think it has great potential for your planned use.

Did not realize the min velocity was 1800 fps for the Accubonds. I have been messing with LR Accubonds, berger VLDs and just switch to LRx for my 7mm wsm.
No sure what to attempt now. I have a .45 CVA opitma elite that is a great brush gun when I lived in ohio but the western mule deer/antelope hunting is much different and was looking for something more and stay above a 40 cal barrel.

In my opinion your gonna be best to stay with a 45 and shoot match hunters or Luke's 310. The sabots will fail you, so much so that I'll give you 200 that I have from my failed attempt. You aren't going to get much better bc out of the bullets you're looking at so I would suggest not making it harder on yourself by building a gun that no one else has had success with. A 1:22 twist pacnor or savage prefit will be your happiest ending, JMHO.

+2 what myers said. The Parker bullets are proven accurate and deadly as are APB 310. The 45's will be more versatile also.

Thanks looks like I will go with that sent Luke another email scraping the first inquiry about a 1:12 twist barrel.
Do you know what velocity I would expect using BH209 for hunting?

If you want to try a fast twist you can get a 1:14 from shilen and probably other manufacturers and try your .35 sabots. I don't know of anybody that had any luck with them but maybe you could hit 2200 and keep the sabot together.

elktalker..........as was stated above: Do yourself a big favor and go with the .45 and those good bullets mentioned. They have been shot successfully by many shooters here on Doug's. And this IS the only ML forum on the internet where you get the STRAIGHT SKINNY. I have not personally shot any of them with BH209 but I am sure a few have and will chime in. I got away from anything that even resembles BP or any of its substitutes. You have the best selection of good bullets in the .45 Richard

I went ahead and ordered 50 of parker's 300gr ballistic extreme and 10 of the 270gr Match Hunter. I am going to send a few done my CVA Optima Elite before I pull the trigger on the barrel. It's a 28" 1:28 .45cal. who knows may shot great of it.
I could always use a new 7mm WSM barrel.

I have shot BH209 and it is accurate but can not swear as to the speeds. I think bestill gets between 2300 and 2350 with 300 grain MH and BH209.

Once you shoot BH209 you'll never go back to Pyrodex, T7 or any other BP sub. Just make sure to weigh it out for best accuracy. IIRC 71grs by weight equals 100grs volume equivelant.
