I have a couple of boxes of the blue 570gr X bullets that I want to load for my 500 Jeffery. However, load data is like hen's teeth... I have the Hornebear (sp?) cases, Fed 215 primers and can get any powders available in the US. Can anyone provide loading data to help me out?

Also, I was reading the book on shooting the British double rifle and noticed that in England you can submit loads to a proof house and they will pressure test them for you (for a price I'm sure)...is there a similar service available stateside?

P.S. "Location" soon to be Lolo, MT...oh, yeah!

there are a number or reloaders on this site that owen jefferys and all of them will be able to help you out

i am having a 505 gibbs built for me and will be using the 600 grain sp pills from woodliegh and ill also be using some 600 grain solids by bridger solids when i get around to ordering them probably with in the next week or so.

i almost forgot http://www.accuratereloading.com/500jef.html

Thanks for the help. I already checked out the reloading page, it only has one load for the X bullet. I'm hoping to get more input before I start experimenting.

Gringo,

I have some 570 X's for my 500 Jeffrey, but I haven't had a chance to work up loads for them yet. I have used Varget and RL 15 with 535 and 600 gr cast bullets, and start at 100 gr and work up. My plan with the X's is to start with 100 gr and work up, with a planned max load of 2400 fps, but I'll take whatever load is most accurate between 2200 and 2400.

The only printed load data I know of is from the A-square manual.
