Investarms
I bought a used(barely) Investarms hawken awhile back, it is in pristine condition. It was made in the 1980's and is a 50 cal. Investarms says it is a 48 twist, but when I measure it, it seems to be a 60 twist. According to Investarms, the max. loads are 90 grains with a .490 ball and 80 grains with a 370 gr. maxi ball. It has a 28 inch 15/16 wide barrel. I have shot it a few times using a 240 gr. lead Hornady PA conical and have worked it up to 80 grains of Pyrodex RS. It seems to be accurate enough to use on deer but I have not really done any bench work for accuracy. I do not have a chronograph, but suspect it is shooting about 1500 fps at the muzzle. What do you think, is this enough for deer within appx. 75 yds? Will this barrel stand up to 100 grains without damage? The Investarms max loads seem to be a tad mild, but I am new to black powder, and plan to use only Pyrodex RS as I have several bottles.
