209 -> Smokeless

[PaulF70]

If a fellow was running Blackhorn 209 and wanted to switch to smokeless powder, is there a conversion chart by powder type or something like that available?

Rifle (the first one) would be a CVA Accura MR-X.

I shoot Powerbelts but I'm guessing would want to switch to bullets that can handle higher velocities if using smokeless...

First thing you’d have to do is put a smokeless rated barrel on it! The factory MRX is black powder subs ONLY! No smokeless.

I do know that, that's what I'm contemplating.

A muzzleloader without the mess would be awesome... 209 is the cleanest of the "black" powders but still I can only get 12-15 rounds at the range before cleaning is necessary..

Never heard of anyone replacing the barrel on an MRX but I’m guessing it’s possible.

To answer your question then, I dont know of any conversion charts comparing BH209 to smokeless.

Yes, you’ll want different bullets for sml velocities unless you use very small charges. Don’t get us started on Powerbelts…

I wouldn’t expect to see that kind of conversion chart. I think it would get people into very dangerous situations and the liability of anyone who published it would be crazy huge.
Plus it will get you kicked out of this forum probably.

I think a smokeless barrel on a MR-X would be great tho.

So this world is just all figure-it-out-yourself? Ok then.

I don't see any more liability in that kind of chart than in any other loading/reloading info. Include a disclaimer: Use at your own risk. With any kind of loading/reloading the user can make an error that causes an accident. It is possible to calculate pressures with powder/bullet combos so there's really no more risk here than any other type of loading data...

It not the liability that you can see, tho. Its the liability that a lawyer can prove.

To give you one comparison from one of my recent range sessions with a smokeless rated 22” barrel.

250 gr Fury
53 gr N120
2227 fps

250 gr Fury
87grW BH209
2286 fps

I think the mr-x has an action that is made of softer metal than the steel needed for smokeless applications.

have you considered selling the mrx plus adding the cost of getting and adding a smokeless barrel to it and maybe a little more and getting a used smokeless here in the classified or maybe a new 45 patriot from woodman ?

That was my first thought - sell the MRX and get something easy to convert to smokeless - Encore, Omega, Rem 700, Savage, CVA Scout .45-70, etc. I suspect you’d have a tough time finding someone willing/able to convert the MRX.

I wonder if that MR-X butt stock would fit on a Scout rifle? That would be nicer than the plain black one that came with mine.
