I searched the old board without a result, maybe not worded correctly.Has anyone tried a 40 cal. bullet out of a 50 cal. factory twist savage ml 2? do they make such a sabot? would you need a sabot within a sabot? and what kind of accuracy have you experienced if such is possible? Thanks for any replies.

I found good results with the Hornady XTP 200gr using the MMP 50/40 blue high pressure sabots. I used 36-41.5 gr of 4759 which is a relatively mild load. Others have had problems with sabot failure with heavy loads, but I never experienced such, but then I didn't use heavy loads eiter.
This is a pretty good deer load and I got 1 1/4" to 2" avg at 100yd. YMMV ;D

I also have tried to seach for these old posts.The search excludes under three caracters making any caliber search worthless.Any hints for finding posts I know I have read,but can't find?

;DI tried many ways to shoot the 200 grain SST from the 10ML and some in fact worked to some degree of success but never as well as I liked. The method of putting an aluminum washer in the base of the sabot worked well in protecting the sabot from drilling at speed, but accuracy was never within my limits.
That is why a great many shooters now shoot either 40 or 45 caliber barrels. This allows them to stay within the confines of "Rick's rule". "If a bullet is less than .060" the diameter of the barrel it will be very difficult to shoot to speed with a conventional sabot".

At what speed? Why do you think this is? Petals too thick and are not opening evenly and consistently? |

rb, what were your accuracy limits? At what speed? Why do you think this is? Petals too thick and are not opening evenly and consistently? I want a bullet that is accurate enough for confident shots at 200 yards. At the time 200 yards was a long way (but even then it was done already with the 50 calber) for a muzzle loader. My complaint with the 200 SST in the 40/50 sabot wasn't so much accuracy as consistency (yes I know they are over lapping ideas) over time. I would shoot one session and be perfectly happy with the load come back in two days and it was terrible. I would then compare with a 45/50 sabot and bullet and not have the same problem. I think that 2600fps is about the minimum worth while speed for this bullet and that was what I was after. The reason for the rule has to do with the part about " a conventional sabot". Normal sabots are made of plastic with some give. When there is more plastic the more give can be had. At a certain point that allows enough movement of the bullet within the sabot that bad things can happen. The amount the plastic might give is heavily dependent on the temperature. So loads that work great one day are not so good when the temperature is 10 or 15 degrees higher. |

What RB says makes a lot of sense. I had good results with them in my 50, but then I used a damp alcohol swab between rounds so things probably stayed pretty consistent from shot to shot.
I also did not use anywhere near maximum loads. I suspect my saboted 40 cal bullets were probably in the 2100 to 2200fps range although I did not have a chrono when I was using them. I don't think I ever had a three shot group of greater than 2 1/2" and had many (most) that were in the 11/4" TO 1 1/2" range which was quite satisfactory to me. I later decided to go to the 40 barrel and use the same bullets without sabots and now can easily shoot them very accurately from 2300' to 2700' and above. I love the light recoil of these 200gr bullets!
If you decice to try them, let us know how they work out for you.

You may want to try Precision Rifle's products. web--is www.prbullet.com-----I just received a packet of 240 gr. 40 cal. to shoot in my 50 but havent tried them yet. They have a pretty good assortment of bullets in varied bullet/sabot combinations. |

Thanks rb and chuck. I do plan to test some things, and will post results when I'm able to do so.
strongbox, from what I've been told those bullets don't do so well at smokeless speeds. Hopefully you're results will be different. Please let us know.

Rb, tried to search on the old board, but since so many are shooting duplex loads it was impossible to find.
Did you ever try a duplex sabot for shooting .40s in a .50, like precision rifle sells? Standard .50/.45 sabot stuffed with a skirt trimmed flat .45/.40 sabot with a .40 bullet?
Anyone?
