I have a new 45-70 scout conversion on the way lrmp ignition. I am curious if anyone has been able to get them to shoot sabotless at reduced velocities. I I have 4756, 4759, 4198 and 4227. I do plan on using a wool wad. I do have quite a few 250gr xtp and 250 gr fury on the way also. This will be primarily a youth gun and does have a brake so trying to stay sabotless if possible but plan on removing if not being able to get them to shoot.

Try about 45gr 4227 with a wool wad, 50-55gr 4198 wool wad, 45gr 4759, would probably be not bad recoil with a 250gr bullet for a youth. I would say no to 4756 as I have tried it in a 50cal and it is way too fast a powder for a sml. I wouldn't go under 45gr powder column in a conversion. In a 250gr for hunting I would use Pittman or Fury, xtp is ok for plinking. jmo

We have killed 4 deer with it the last two years the furthest being about 125 yds. . 20gr pushed a 250gr xtp close to 1800fps. I know it is quite fast powder but with a small framed shooter it kicks about like a 22mag. I was thinking it was close to blue dot. I will make sure to check the powder column length so the bullet doesn’t get into the old chamber.

35gr is not a long enough powder column to fill the remaining cartridge case area in a conversion rifle, I ruined a barrel so my experience with that issue was a bad one and expensive. You need enough powder in it to put the bullet fully in the rifled portion of the barrel or it will cause flame/pressure cutting in the barrel. Just trying to save you some head and heart ache. The 4198 loads would be your best option.
Also with the 50cal and 4756 you did not have a cartridge chamber area to deal with and could shoot much shorter powder column. I tried that powder once in my ML2 at a little higher charge and it shredded sabots so I never tried it again.

You could start at about 45gr of either 4198 but you will most likely have to use either a veggie or wool wad. I wouldn't go under that column amount of powder.

You can still use the brake with sabots.

I know you have shot a ton of Bullets have you show any of those smaller sst? 50gr of bullet weight probably won’t send out over the deep end on recoil but glad I can step down to the 40cal and harvester sabots if I am unable to get theses to shoot.

Funny you mentioned those 200 FTX/SST's? I shot a few yesterday but with my heavy barreled bolt gun using 69.5 grains of 4227 at 3300 fps into a .864" 100 yard 3 shot group. No wads.

Your previous 45 700ML/Brux has also been being used as a test bed for saboted 40 cal bullets, specifically, 240g, annealed, knurled CEBs in HLBSs but with wads. Haven’t tried w/o wads but will now. You were the first to really try high speeds in saboted rounds. That’s well over 10 years ago. I’ve had excellent accuracy to a little past 3,000’/sec. knurling and easily obturated bullets have performed best for me.

Doubt the break action will tolerate those speeds😀. But good to know they will shoot. Bet that load would vaporize a groundhog.

Just to verify those were 45 or 40 cal sst/FTC? Doubt the break action will tolerate those speeds😀. But good to know they will shoot. Bet that load would vaporize a groundhog.
