I'm new at reloading rounds that don't fit in my decades-old Rock-Chucker...so here goes. Just loaded up my first two loads, four each to try out tomorrow.
- 105gr IMR4831, 500gr Woodleigh SP, Fed 215, no crimp
- 85gr RL15, 500gr Woodleigh SP, Fed 215, no crimp, Kynoch filler wad
Got 'em out of "Shooting the British Double Rifle." Sound about right?

My own 470 NE was regulated 101 grains IMR 4831 with a 500 grain Woodleigh. The velocities are 2150 fps and it is an accurate load. You should chornograph the loads in addtion to seeing where they shoot.

I think that you may find the 85 gr. loads a bit light, but that is a good starting point. My .470 NE regulates with 90 gr., both softs and solid Woodleigh's.

I hope it was clear that I was referring to the RL 15 loads.

Matt:

Before you start shooting ANY suggested loads, ALWAYS START WITH LESS POWDER THAN IS RECOMMENDED AND ALWAYS START OVER A CHRONOGRAPH!

The last thing you want to do is start off shooting hot loads in a new gun. Although it may be the same powder, numerous guys on this forum has stated that they have gotten higher (and lower) velocities using the same powder, but with different lot numbers.

Start low and work up.

I'm sure guys with much more experience than myself will chime in with more specific recommendations.

Here is information from one of the resident DR reloading gurus, 400 Nitro Express:

Mac is absolutely right. What you're seeing there is normal. Of course, no two guns are the same but, the lot to lot consistency of the density of cannister grade powders....ain't very consistent. That's why the manuals advise reducing 10% and working back up when a component is changed, including lots of the same powder.

In .400/.360 Purdey (9.3X74R case slightly shortened and 300 grain 9.3 bullets), I've had otherwise identical loads - same bullet, case, primer - but with the same charge of two different lots of IMR 4350, make a difference of 200 fps when fired back to back in the same range session. Regulation went from perfect to 4" wide. With the old lot, I was at 51.5 grains for standard velocity and perfect regulation, but had to go to 56.3 grains with the new lot to get the same velocity and regulation. You've gotta work back up over the chrono when you change lots.

And yeah, buy a large cannister, or several cans of the same lot.

Sound about right?


Your load is very similar to what I use other than the fact that I started crimping sometime after developing that load. After doing so, I noticed my velocity picked up slightly and I had to adjust my loads for the gun's regulation. For example, I was shooting around 88-89 grains with no crimp and reduced it to 86 with one.
Hauling these types of cases around uncrimped in the bush could end up being a problem for you.
