Is it possible to start a treed for the beginners on what people are shooting for loads & also duplex loads. Also when you talk about (DUPLEX) is it mixed or 2 separate tubes of powder? Its best to be SAFE THAN SORRY.

fine with me. If we dont have load data for such and such guns/barrels, its not very helpful.

Mine is also a CVA Apex with a savage breech plug with a .030" bushing instead of the vent liner. My load is the duplex 10 grains of IMR 4759 first followed by 52 grains of H4198 underneath a 250 grain Barnes TMZ with a wool wad.  Primer is Winchester 209.

you should have a section for SML since its becoming very popular...this way people in the know can help others and be safe about it....I myself want to try SML ..but mostly for target matches and shooting....

its a very interesting concept in shooting...there is a video on yuotube of a guy shooting a SML custom out to 1200 yards to hit a metal plate...took 5 shots to adjust with the spotters info..but he did it...

That was my whole intent of the topic. When I first got into muzzleloader I learned as I went, after braking 2 TC Encore stocks, I found the problem. 3 pellets = 150 grs. powder, OH NO, 150 grs. 3FFF
T-7, that was the problem.. I JUST WANT TO MAKE THE TRANSISTION FROM BLACKPOWDER TO SMOKELESS POWDER TO BE SAFE FOR EVERYONE

"you should have a section for SML since its becoming very popular."

That's the heading for this section.  Smokeless Muzzleloading


I shoot 31.5 gr of 2400 behind a saboted 260 gr. PT Gold. It's not a duplex load. This is in a stock Savage ML 10 II.

CVA APEX Slufoot conversion. I was shooting Barnes TEZ 250 on top of a dry felt wad pushed by a duplex load. 10gr 4759 & 48gr 4198. I'll be using the same load (at least to start) with a FTX 250 resized to .4495 I also use Fed 209A primers

You do have to put the powder in separate tubes & dump in the 10gr charge first as it is the booster.

I use a RCBS Chargemaster to weigh & dispense every charge & then also weigh each charge on a second scale. It's really the only safe way to do it.

Hope this helps to explain the process,

Greg

So far this is great we as new shooters to the smokeless side can composite a list of powders to get started.

For a youth/reduced recoil load I have had good luck with 30-33 grains of IMR 4759 with a harvester light blue sabot and a 200 grain SST. You can also substitute the 195 grain Barnes. Out of the 45-70 Apex barrel it is good for close to 2000 fps. My seven year old son was able to shoot it. It has more than enough for deer at less than 100 yards.

The good thing about the duplex if it is mixed is it doesn't create an unsafe condition. However you do lose the benefit of the booster powder.  One of the guys on another board tested mixed duplex loads of 10 SR4759 and 60 H4198 and saw no issues. The result though is a decrease in speed when mixed.

I did have an Apex 45-70 conversion but it got sold before I ever shot it.  The load that had been shot by the pervious owner was 10 SR4759 and 48 IMR4198.

Guys I can't emphasize safety when it comes to the SML's as far as loads, and shooting, and creating a data base or list of proven loads is a great idea. One thing that i will emphasize  since if you do double charge one it can surely give you a significant  emotional event in your life, is always put a witness mark on you rod, do not get side track while shooting talking to other shooters, and if in doubt dump everything out, and star over.
As far as loads go, here is what I have shot out of the APEX, and TC conversion, and in my mind it is safe with out any problems.
The main charge has always been H 4198 or IMR 4198, and I have always used IMR SR4759 for a duplex, and yes when you use a duplex the 10 gr. of the duplex goes in first and then the main charge. If you mix the two which it can be done you are really defeating the purpose of the duplex load which is quick ignition in cold weather, less recoil/speed. Unfortunately 4759 is being discontinue, and I'm trying to find a safe replacement for it. It might take sometime, but I'm getting closer.
Now the loads I have shot so far are as follow:
The powder has been IMR 4198, and the booster for duplex 4759, and I have also shot just single charges of 4198.
Single charges have been 58 gr., 60 gr. and 65 gr.. I will not go beyond the 65 gr., it is plenty for 200 yrds, and beyond. This load have been all sabotless, just make sure you do have a good compress load. You can also use this loads with the 200 gr. .400 SST's and the blue sabots.
Duplex loads are as follow: 10/48  4759/4198, and 10/50 4759/4198, this are great and safe, and work great, under all conditions.
I hope this helps out a bit, but if any one has any questions fell free to ask.

That would be great to have a date base for loads and safer for new shooter. this sport is slowly getting bigger everyday and can see where this would help.

A while back I bought 2 cans of SR-4759 not knowing I would ever need it as I did all the other powders I bought from Powder valley. Using 10 grains as a duplex load should last me the rest of my life now 79. Don't know why powder makers do this is it because it wasn't a good seller? any one know the reason. Doug's message boards has a wealth of loads for the SML'ers and a great bunch there as well as here   Lou

Guys
What a great topic. I am having my .45 Apex converted by Hankins Custom Rifles.
 He recommends Max load 50 gr 4198, never mentioned duplex loads. Great suggs. though.

I am not sure but IMR-4198 powder is some what difficult to ignite so the Sr-4759 helps solve that problem so I have been led to believe. I know when the Savage ML'er II was fist out 4198 was getting a lot of misfires. I shot 65 grain of reloader 7 with a 250 grain bullet had outstanding accuracy.

That is some great shooting, and specially with a 20" barrel. You are the right track, and it only gets better from here. Stick with the duplex load and you will never have a problem out of it.

I have 5 pounds of RE-7 from when I had my savage  I would like too know if any one has tried it in their guns and what would be a good starting load. The load I use to shoot was out of a 50 caliber with sabots but now I have the 45, 2 Encores, a buffalo classic H&R conversion, and a Remington ML/ Brux being built as we speak Thanks
