Really big bores burn lots of powder like my wildcats, and short barrels defeats the purpose of
getting the power out of the charge as well as
you need the weight to tame recoil.My little(458HE)
cartridge has 27" barrel on one gun, but everything else is 30" or more.Never could see making barrels short, adding brakes(still adds length), which causes noise problems,
when you could have barrel in place of brake
giving maximum power; and use right stock design,
add wt, good pad, till it shoots comfortable.Ed
