I have owned multiples of most of them, 32, 36, 38, 40, 44, 45, 50, 54, 58, 62.
If you want flat shooting, low recoil, very accurate, go with the .40 cal. It bucks the wind better than the 32 or 36, has more Umph at 100 yards, little bit larger to handle for my clumbsy fingers, and if you want to zip it along it will do over 2000 FPS with a round ball & knock the snot out of a coyote at 100 yards. Or drop it to 15 grains of Swiss or GOex & shoot 1 hole groups at 25 yards.
Also it will knock over the sihoulette plates at 100 yards & the .32 & 36 will not, just not enough Umph in them.
Just a all around Superb caliber & my favorite in a smallbore rifle....
