Thanks,

Contact the gentleman with the handle 465H&H, who happens to be located in Idaho and has one of said rifles with substantial elephant mileage on it.

Standards for the .500/.465 are 75 grains Cordite behind a 480 grain bullet for 2150 fps MV from a 28" barrel and 14 tons BaseCUP. ME is 4930. Current technology max pressure is 35,534 PSI (lowest chamber pressure of the .400/.450/.470 group).

Late run Cordite ran 2100 fps in CFA's 26" barrels. Handloads with 480 grain Woodleighs gave perfect regulation at 2100 fps as well.

All of the old double rifles shoot a 400 or 500 gr. or maybe bigger if you really get wild and all at about 2150 FPS max, or mighty close, so one caliber, in reality, is just like another..Best to choose by component availability and cost of shooting them IMO.

Boy is that alot of crap.

So there is no difference between a 400gr bullet at 2050fps and a 480gr bullets at 2175fps? The difference between a 450/400 and a 450 No.2, yeah, right.

So there is no difference between a 400gr bullet at 2050fps and 2150 and a 520gr bullet? The difference between a 450/400 and a 476WR, yeah right.

And there is no difference between a 400gr bullet at 2050fps and a 570gr bullet at 2150fps? The differenc between a 450/400 and a 500NE, yeah right.

and of course I could keep going.

Bullets were also supplied in 420 gr and 365 gr weights. Whether rifles were regulated for these weights or they were loaded to regulate in rifles regulated for 480 gr bullets , I do not know. Powder charges for the 480 gr weight varied and included 67-70, 71-73, 75 grains.

thanks, I should have just callled 465H&H. What is your load, if you do not mind sharing? I traded into this 100+ round box of Kynoch primed brass, and it just keeps talking to me about a SS stalking rifle. I know, makes no sense, but I think I need one. What are actual bore and groove dimensions?
