can some of guys give me a prescription for 180gr speer fn in the 35 remington:questionmark:
Great news so I guess I'll have no problem, far out."Am curious if I can match the 300 Savage velocity with the same bullet weight, say 2300 to 24000 fps."
Well, granting that only space vehicles can go 24,000 fps, yes, you can match that velocity of 2300 plus. 42 grains of H335 will get you there, as will 41.5 of 3031. I'd start around 37.5 grains with either and work up. Since I suppose your XLR has the longer barrel, this should be quite easily done. In fact, I can reach that velocity with a 20 inch.
