What is the standard load for the 470NE with 500 gr Woodleighs and Fed 215 primers???


Mike

I don't think there is such a thing if your meaning powder, powder charge and case. Each manufacturer has their own recipe. If yoyu mean velocity and pressure than 2.050 fps seems pretty standard out of a 24" barrel. I don't know about pressure.

If one was reloading for the 470NE what is the powder charge one would use fora 500gr soft point...

Since the "modern" rebirth of the double rifle there have been 3 different "standard" Powder charges with 500gr bullets.

First there was @75gr of IMR 3031. Filler required.

Then there was @100gr of IMR 4831.

Then there was @89gr of RL 15. Filler required.

These powder charges might have to be adjusted up or down a little in individual rifles and usually, but not always Solids take a grain or three less than the Softs, but they are in the ball park. As always start a little lower and work up.

I have helped people develop loads in 470 doubles using all 3 of theswe powders.

In my 450 No2 I have developed loads with all 3 of these powders that seem to be of equal regulation and accuracy.

RL 15 appears to me to have less pressure.

Thank you Tony...

You are most welcome.

Hope to see you at the next DSC.

Mike:

I use 85 grains of RL-15 for my Francotte that works exceptionally well with Fed 215 primers and 500 grain Woodleigh softs. You may want to start a little lower than 89 grains at first if using RL-15 - but that is just my gun and RL-15 lot.

It will take about 3 grains of filler with that load.

My .470 regulates perfectly with 106 grs of IMR 4831 behind a 500gr WLSP

mine likes 91 gr of RL15

112 grains of H4831SC and a Swift A Frame Fedral 215 primer of course; worked in my Merkel for a 2" group at 25 yds off handed. I probably could get them to touch from a set of sticks.

Retreever,
According to the Alliant web site (pressure tested)
They recommend:
Powder,Min. Weight (grains),Velocity (fps),Max. weight (grains), Velocity fps)
RL 19 111 2159 115 2244
RL 22 113 2167 117 2234
I am going to try the RL 22 in my Krieghoff this weekend, will let you know.
I have also used Accurate 5744 with gold dot pistol bullets but found the powder too dirty for my liking.

Mike,
Per our phone conversation, R-15, start at 82grns and work up! I shot the Francotte with Mark, and found that 85grns was spot on, over a chrono!

I haven't posted here much of late but I have done some testing with my preferred powder (H4831sc because no filler to mess with) over the summer and written about it elsewhere.

In a Heym 88B, using Norma brass, Fed 215GM primers, and woodleigh 500 wc, and testing pairs of loads at 45* - 98* F:

a range of 102gr to 108 gr charges gave velocities of 2000-2050 fps at 45*F (stopped here at crossing. 113gr is the max listed load in A2)

SD was 31fps
+/- 1 grain powder = +/- 33 fps at a given temp
temp variation was 1.4fps/degree F -or-
+/- 24*F = +/- 1 grain powder.

best regulation for my gun was at 106gr (2033 fps at 45*) but this load crosses badly above 70*F

I have settled on :

104 gr for 40-110* F
106gr for 10-60*F

special thanks to the six sigma dude who helped with the statistics

it just depends on the rifle and bullets. With cheap chronographs there is hardly any necessity for a standard load anymore, and probably why the factory cartridges typically have such low velocities.

I would surely start low. In my case 85 gr. RL-15 + wad chucks out 500 gr. NF FPS at 2200 fps.

Using the R-15 with dacron or foam filler you will be burning less powder than with the IMR 4831 or any of the R-19, R-22 powders so you will have less recoil, which in my book is always a good thing.

Hey Guys,

Had to go out of town last minute, so no range report on the Reloader powder. Will be out of town and country for most of Sep. So it will be some time in coming. But I will post the results as soon as I get them.

Cheers
