Got some jacketed bullets, 22 Cal .224 75 gr BTHP, given to me. When trying to find load data the heaviest bullet listed is 70 grs. Any one know where I should look?
Powders on hand are 3031, 4895, 4064, Win 746. I see these powders used in various bullet weight for 220 Swift but nothing over 70 grs.

I really don't know if the standard rate of twist in the Swift barrel will stabilize a bullet that long. Takes a 1 in 8" or faster in the .223/5.56 for a long bullet like that.

I agree. Trade them for some 55 gr.
