Shooting Smokeless Powder in my Remington 700 UML w/ target

I'm bound to create some controversy with this post, but I've been doing this for 3 years. Black powder and black powder substitutes are not to my liking. Those have too much mess and too much to clean-up afterwards. By studying low pressure smokeless loads in my Nitro-for-Black double rifles, I've come up with a smokeless load for my Remington UML. THIS POST IS TO TELL WHAT I HAVE DONE AND NOT TO RECOMMEND OTHERS TO TRY THIS - This is the ONLY model muzzle loading rifle that I would dare to try to use smokeless powder. The Remington 700 UML is a true 700 action with a special barrel and breech. (see pics) The UML is so much like a conventional Model 700 that BATF requires it has to be purchased through a Licensed Federal Firearms Dealer, just like a regular modern centerfire rifle. Unfortunately the UML has been discontinued and those on the used market are going for about double their original retail price.

My loading procedure is as follows ..... I pour 38g of AA5744 down the barrel - then I push the "sabot only" down the barrel, seating it HARD in one continuous stroke - then I drop the bullet down the barrel and seat it into the sabot with 8 firm raps - finally, I insert the Remington special primed brass case into the chamber. By seating the sabot separately, without the bullet, its much easier to load than trying to force the sabot with the bullet inside down the barrel. I consider 38g of AA5744 safe and MAXIMUM in my rifle. At just over 1900 fps its a good load for my area. It covers zero to 200 yards which is the maximum range for hunting whitetail deer on my hunting land. My rifle is sighted 4-1/4" high at 100yds, which is 4-1/4" low at 200yds. So zero to 200yds I aim at the top of the heart. (at 225 yards, the bullet would strike about 9 inches below aiming point)

With the rifle sighted dead-on at 170 yards, the target below shows a 3/4" 3-shot group at 100 yards. (bullets strike above center aiming) The measured velocity was 1908fps average. (sd was 7fps) - Velocities were measured using a Garman Xero C1 Doopler Radar Chronograph - velocity accurate to with 0.10 fps. The 3 circles below center show the expected impact at 200 yards.

There comes a point where people who don’t really like the essence of muzzleloaders should probably just use a centerfire rifle. My 2c

I agree, but if you want to hunt in a Muzzle Loading Only Season, and don't like the mess and clean-up of black powder, you have to improvise.

Which violates the spirit of the season. It’s the same as able bodied (I’d argue anyone though) hunters using a scoped crossbow in archery season. They’re imposed limits for a reason.

I’m all for innovation in hunting methods, but not at the expense of the seasons. Good work with your gun though. Enjoy it.

As long as its within the State Law, I have no issue. Here in Wisconsin, crossbows with scopes are also legal, as are scoped muzzle loaders using smokeless powder.

I've had several Savage ML rifle's that are specifically built to use smokeless powder, but always loaded on the conservative side of the load tables. In my experience, accuracy wasn't to be found at the max end of things, so there wasn't any reason to push the limits.

Whether it's race cars or rifles, when you max things out, sooner or later you'll run into trouble.

I have a Savage ML and a NULA ML that both shoot smokeless. I love using a single shot rifle and often carry the NULA during firearm season in Maine.

It’s ridiculously, almost prohibitively, expensive right now from retailers, but have you had any luck with Blackhorn 209? I’ve had reports from customers when I worked retail that it was a fantastic powder and made cleanup a breeze.

 

[buckstix]

Blackhorn 209, like other black powder substitutes, requires diligent cleaning after use, or else the remaining residue will absorb moisture, and severely rust the bore.

There are dedicated smokeless muzzleloader actions available on the market. Put a purpose built centerfire barrel on one and you're good to go. I've built them on the Savage smokeless ML action, a Remington action and a Mesa action. All are safe and relatively no guesswork. For anyone contemplating the latter is available from:

Muzzleloader Action % - Pure Precision

The SUMMIT MUZZLELOADER ACTION has all the same great features as the SUMMIT centerfire actions but is designed specifically for long range muzzleloaders. The first main change is the slotted bolt face that was created to use priming modules from Hankins Precision and Arrowhead rifles. The slot...

Yes, but those are pushing an additional $1,000 cost. Mine is working fine at no extra cost.

You like that 5744! I remember years back one of the your first post that I read was about reduced loads with 5744 and I commented not to use fillers with it, which at the time was conventional "wisdom", even was noted in literature from the manufacturer. You corrected several of us about the filler and I realized the experience you have, which seems to be vast. The 5744 has worked well in my 470 Nitro playing around with testing bullets at lower velocities.

Interesting setup for the muzzleloader, not for everybody, but it surely seems to work.
