Smokeless hunting load help

[dhagz]

Good morning,

I have been reading posts here for a couple years now, but I am in need of some help. I have a professionally built buy a reputable builder custom smokeless muzzleloader. I have been told that the .50 caliber barrel from green mountain barrels it has, is designed to be used with the same published loads as the now discontinued Savage 10ML also its built on a Remington 700 stainless short action and uses the arrowhead rifle breech plug and ignition. The issues is he has since changed carriers and I am unable to reach him with questions now. The gun shoots well, I was able to clover leaf 3 shots last year when sighting in at 120 yards for deer season. 44 grains of AA5744, large rifle primer, a sub base, and the Remington premier expander 50 cal 250gr. I love the gun, thing is a hammer i have shot 3 nice bucks with it and all 3 dropped where the stood. Now my problem is I can not find the powder or the 250 grain Remingtons.

I see on the forum here a lot of guys are using the Harvester sabots, would this replace the sub base or what is the purpose of them?

I have tried the Hornady 250 gr sst and they don't group near as good for me. Any recommendations on other powder, or do i need to get some of the harvester sabots?

I know there’s alot of info in the forums here but I’m nervous to shoot something without being told it’s specifically for my gun as I am very new to the smokeless front loader, I am strictly worried about it from a safety stand point.

Thanks in advance for any advice you may have, sorry for the lengthy post.

First off the Remington sabot and bullet is ONLY available through Remington. Barnes wont sell the exact same bullet and MMP wont sell the exact same sabot. The Barnes 250gr TEZ bullet is similar but the sabot is much different. I would suggest swapping the sabot for the Harvester RED Crushrib and ditch the sub base.

The SST comes with the MMP 3P-EZ sabot. It is likely way too small for smokeless applications. The Harvester "Smooth Black SHORT" would be the next size up.

As far as powder you can get the same speed as 5744 using about 4-5gr less of N110. About 38-40gr of VV N110 will give you nearly identical speed or a tad more. SR4759 is another excellent powder if you have any. Its no longer made but a great powder for 50cal SMLs.

How many would you like Bullet and sabots from Remington for the Rem 700 Ultimate Muzzle loader I have maybe 35-50

That will be a help for some.

Thanks very much for the help guys. I was able to source some of the red harvesters and some VVN110 powder. I’m hoping to get shooting it this week. I will let you know how I make out.
