RL15 powder for .470

I'm not sure if this should go in this forum or reloading but is RL15 the preferred powder for
a .470 NE?

I know that RL15 requires the use of filler to take up the empty space in the case but I see that it is popular with many folks.

What does the AR community say?

Thanks

RL 15 works very well but I don't know if I would use the word preferred. For 20+ years I have been using IMR 4831. More is needed and it has more felt recoil than RL 15 but it fills the case to the bullet's base and since there has never been a problem I never saw the need to experiment further as all my chronograph work and target shooting was developed with 4831.
Just my 2 cents but many here will support RL 15.
Cheers,
Cal

That would include me. I shoot RL15 in my .470 and use a Kynoch wad. I think Federal is actually loaded with RL15 too, but they use their proprietary F216 primer in lieu of filler.

I haven't experimented with RL15 in my Searcy because Butch provides his regulation load.

Mike,

Do you have a source in the US for the Kynoch wads? I have been thinking about using dacron but for some reason it freaks me out a little. I don't know why, there is no good reason for it. Maybe it is because I'm not used to filler at all.

I have a PDF of "Reloading the Nitro Express" by Ross Seyfried in which he advocates the use of RL-15 plus filler for Vintage Double Rifles.

I will be glad to share it. Since I cannot post this article here, I will be happy to send it to you. Please contact me directly at rkmojo@aol.com

Since there is a scarcity of RL-15, I would remind you that RL-15 is just another batch of Norma 203B, that was sold to Alliant and repacked.

Or you can pick up backer rod at Home Depot in 1/2 inch for a fraction of the cost and almost the same stuff but in a roll you just cut yourself.

RL 15 (with Kynoch wad) gives me more uniform velocities and certainly reduces recoil.

I have had much better experience with RL-15 that 4831. Less recoil, seems to shoot slightly better single barrel groups. I haven't seen any difference between 5g of Dacron and Kynoch wads

I settled on RL15 and Kynoch wads in my 470 Merkel and then I got a Searcy from Butch with his favorite load using IMR4831. I can interchange the loads between rifles and they chronograph about the same at about 2160 with 500gr Woodleighs, TSX or CEB's. There is a slight increase in felt recoil with the IMR4831 loads.

Hell, fellas, I guess I will try some RL 15 this summer. But I've a few kegs of 4831 to shoot up, too.

Cal just shoot moor and use all that stale powder up. I think one of the reasons RL 15 is popular in the older vintage rifles is the burn rate and pressure curve is close to loads using cordite. It may help some rifles to regulate better than some other powders.

The recipie I got from someone here was 85gns RL-15, 5gns of Dacron, and Fed 215 primers. I've used this with 500gn solids and 500gn cast bullets. They both shot to the same point.

Use RL 15 for 450 NE and for 500 NE
Excellent performance

I have had success with both 4831 and R-15 with individual rifles showing a definite preference for or the other. I spent many range sessions with my 470 Evans with R-15 to no avail until I tried IMR 4831. It shot lights out with 4831 but wouldn't shoot at all with R-15.

I always let the rifle decide.

Just came across the thread late. Sounds like most folks use 4831 or RL 15. I use 107gn RL 19 and get excellent performance.

I'm in the minority here which could mean "operator error" as I had terrible results with RL-15 in my 450NE. Erratic velocities, way outside the standard and mediocre accuracy. IMR 4831 did well, but I settled on H-4831. Less temp sensitivy and it's what Hornady uses.

I prefer to use RL 15 with a filler when I can, but I can absolutely confirm 470Evans data,as I also shot his rifle with both powders.
His rifle definately prefered IMR 4831.

Oh, and do not even ask him how his H&H Paradox Gun shoots With his reloads. It is SCARY accurate...
