I am wanting to try Accurate Arms XMR 2015 in loading for my 45-70 (an 1895 Marlin); but I am having trouble finding it locally, and haven't been able to use it yet. I have heard good things about this powder in the 45-70. Have any of you used it? And with what results?
I had a heck of a time finding AA 2520. Has anyone bought powder from a store on the net??
If it's cute and fluffy it must taste good!!!
I can't find it eather but for the bullets I use, Hodgdon's works better for me.Originally Posted by BigBrass
Here is some .450 Marlin loads from Rick Jaimeson using AA2015 in a 24 inch test Barrel.Just for an idea only as it is the .450 Marlin,not the 45-70.
Hornady 350 gr Interlock--58 grains for 2170 fps and 40,200 PSI 24 inch
Speer 400 grain FN--52 grains for 1987 fps and 40,200 PSI 24 inch barrel.
It appears this powder gives excellant accuracy according to Ricks test.1.5 inch groups at 100 yards with the 350 grain and .90 groups with the 400 grain Speer.
Best of luck............Jayco.
jrank 45-70: I have bought powder on the net from powdervalleyinc.com. Their prices and service were good.
jayocreek: Thanks for your comments. I have heard about good accuracy from this powder from a number of sources, in the 450 Marlin and the 45-70.
Hey BigBrass. One of my favorite loads for the 45-70 is:
300 gr Hornady jhp
51.0 grs 2015
1850 fps out of Ruger #1
This load shoots 1/2" groups and is very pleasant to shoot.
I'm surprised that 2015 is so hard to find. Judges in Winchester Tn stocks it all of the time. Great powder. I also use it in my 30-06 pistol and rifle. reflex264

I note that on the sixgunner.com website, Paco Kelly has an article regarding loads for the 45-70, for different strength rifles. Here is an excerpt.
"Then there are the level three rifles [which include the Marlin 45-70s], and most likely the largest user of .45-70 ammo in our game fields. If any animal in America won't fall to a well-placed shot from a .45-70 level three power load then as a good friend said, "you shouldn't have gotten into an argument with it in the first place."
"When you are pushing a 350 grain Speer jacketed flatnose at 2050 fps and almost ton and three quarters muzzle energy they are not going to talk back if you do your part, (57/AA2015). I would brain an elephant, without hesitation, using a heavy jacketed 458 magnum designed bullet in 350 grains, like the Hornady 350. How much more power do we need for hunting in the lower 48 states?
"The largest animal you can take would be a buffalo, and he's no risk. But just in case that is not enough then Speer makes a 400 grain bullet that you can push with 53 grains of AA2015 and 1900+ fps velocity, as will 57 grains of H335. These two loads of 2015 powder must be worked up to, they are top loads. Don't think that I lowered the powder charge to be careful for you, I didn't. The usual good advice: Start 10% below and work up.
"LEVEL FOUR: The more modern '86s by both Winchester and Browning are so strong that powder room becomes the major factor in reloading for these big leveractions...almost.
"The all-around velocity champ, AA2015, under the 350 grain Speer will push that bullet out of a 24 inch barrel at an easy 2300 fps and an astounding 4100 plus lbs. of muzzle energy. You are talking very close to the African Rifle power levels of just a few years ago. Switch to the Hornady 350 grain heavy jacketed bullet and it is a thick skin killer of African game with a much faster second shot then any other rifle, other than a double.
"With this load, and a lot of practice, I was able to put four shots into a 100 yard, 12 inch circle, faster then a bolt action rifleman could put two into the same circle. Firing from the count of three I was able to fire two rounds before he could clear the spent shell from his first shot. It takes a lion about two seconds to charge you from 50 yards. I could hit one easily twice. And this load would turn a lion inside out.
"Winchester has just re-released it's model '86 in a 24 inch taken down rifle. And it is beautiful! It is also heavy, but when you are using loads like this you need the weight. I think this new Win '86 45-70 take down, with an octagon barrel, is the finest moderately priced African Rifle now on the market. When you pay the big boys up to 3000 dollars for their African and Safari Grade bolt guns, and 20,000 plus for good doubles, $1100 for the Winchester is moderate to a fault.
"The recoil on this rifle with heavy loads is really not bad, because of its weight. Now that is relative. If you are used to .45-70 Marlins with medium loads, the jump to this won't take long. But if you have been shooting .30-30s all your life, you will have to work up. Saying this, I have an early 20s daughter. She beautiful and petite - and she handles full loads in this rifle without breaking a sweat. She had to work up to it, but it didn't take long. Now she can follow PACO'S RULE...out to 250 yards, that's 250 rounds, without problems.
"With the 400 grain bullets in these '86s, 2100 fps and just under 4000 ft. lbs. is possible, again with 2015 powder. I use 58 grains for 2100 plus fps. We are not far from the power of the .458 mag with these loads - about one fifth away."
Buy the Nosler #5 load book.Nosler loves this powder for the 45-70 and 300gr nosler bullets.
Nosler #5 does not publish 45-70 max loads(40,000 CUP).Originally Posted by Riflemanz
The load book states 35,000CUP.The loads listed state MAX for the 300gr
nosler bullet.Their MAX load is all i want to go! Nosler states these loads are designed for average pressures of 35,000 CUP. When we reload,we have no way of knowing how much higher the load really is above average.So i stay at their MAX load or below,i don't want a Kaboom!!!
Nothing has ever gone ca-boom at 40,000 CUP.Hell,Buffalo Bore ammo is over that without a law suit yet.Why would Hodgdons and a couple others go with 40,000 CUP and Hornady and Marlin came out with the .450 Marlin to get the most out of there rifles at 43,500 PSI?Same action exactly.
