I'm thinking a 45-70 (Marlin Guide Gun) might suit me for my next big game rifle; but I'm looking for versatility.
Anyone have experience using a saboted bullet in this cartridge?
I'd like to try a .35 cal speer semi spitzer or something similar in a sabot, stuffed into the 45-70 case. Anyone tried this? or even a 180 gr 10mm SP?
I've shot muzzleloaders stoked like this quite a bit and was impressed with the results- but what about a smokeless powder rifle? Do you think it would work out alright?
Just thinking out loud.

If you are thinking about reloading for this rifle, It uses 45 cal bullets which are pistol bullets the same as what most sabots consist of. IE a 54. cal will use a 45 cal bullet and a 50. cal will use a 44 cal bullet. some muzzle loader's will have different size sabots so you can use either a 45 or 44 cal bullet.
also if you are thinking of putting a sabot inside of the case that is looking for trouble.

The sabots I'll be using are .451 diameter (outside) with and internal cavity diameter of .358 or .400. Why is it "asking for trouble" to put a sabot inside a case of the same mouth diameter? Remington has done this for years with their .30 cal accelerator rounds; plus- it's a fairly common practice for many .50 BMG shooters to use sabots when a smaller diameter bullet is desired in that large case.
I'm asking, specifically, about doing so in the .45-70.It typically has large, deep rifling grooves. Much like a muzzleloader.
I'm aware that I'd most likely need to crimp the case mouth to ensure everything 'stays put'. Also, the bases of most sabots are concave- much like a minie ball- to facillitate proper gas seal.
What I'm asking is if anyone ACTUALLY HAS EXPERIENCE with this, rather than supposition or speculation.

Sorry, I haven't tried it either. I know sabots have been used in the 06, and I'm sure you know the common complaints about them. Plastic fouling, and mediocre accuracy. I don't think you'd have the fouling problem as bad in a .45-70 however. Simply because of the velocity. Accuracy may not be as good as with a bore-sized bullet, but you won't know until you try. The only thing that could be a problem is loading and feeding them in a lever action.

Now, all that is assuming you can get your hands on some sabots that will actually work. 45 cal muzzleloader sabots will not work in your 45-70. They are designed for a .451" bore, and the 45-70 has a .458" bore. I'm sure they would shoot, but your accuracy would definitely suffer.
