I have only ussd relosder 15 for all my 416 rem mag loads .There is none to be found these days becsuse of the war in urikraine .I face the same problem with my 338-378 weatherby using r25 none to br found .I did buy the only keg of r15 this summer but its in Alaska .I hope both of them return .These to big rounds are keg eaters too use alot of powder.

RL15 is available from time to time. Precision Reloading had some over the weekend. Powder Valley occasionally gets it also.

15.5 is close. I tested it in my 450 against one lot of 15 that I have. Was suprised to see that it was faster. Probably just needs about 2 grains less on a 80ish grain charge.
