Anyone have reloading data for Swift 470 nitro solids

[duckfish]

Anyone have the reloading data for these I called Swift, but they have not gotten back with me. I have the book, but these are not included. Any help would be greatly appreciated

JJ's load for a Heym A-frames 79.0gr IMR3031 with 2gr Dacron over filler or one of the commercial plugs!
For the Break-Away solids Bill (owner) at Swift said reduce load by 1.5-2gr, He said about the same
'Reduction in powder charge for most bigger calibers and I've found that works well in 450-400 double
and 375 H&H and 416 Rigby!
In all 3 of my doubles that formula with very little fine tuning gives same point of impact and same in the bolt guns.
Hope that helps! Knowing what gun u own and what loads you have been able to regulate with would help! I have a lot of data I've tried in the 470NE and so I happy to share my experience.

77gr is typically the standard "soft" load for a vintage 470NE using IMR3031.

79gr is very high with 3031 for a soft. It would be exceedingly high for a solid. (usually 1gr-1.5gr LOWER for a solid than a soft)

I would start at 75gr of 3031 with dacron on that bullet and work up in 2-tenths a grain increments until regulation is found.

What you can get away with in a Modern Heym is far different than what you can safely use in a vintage gun or one from a lesser make. These are double rifles, so we don't care about velocity, we just want regulation. MOST 470NE find regulation between 75gr and 78gr.

My best load for this was RL 15.5 at 84 grains
