Unlike our other Anti-Personnel 44 magnum loads, this one utilizes a hard cast bullet, which will not mushroom and the resulting penetration is very deep. Expect at least 24 inches of straight-line penetration in mammalian tissue, thus allowing this load to also serve well on small to medium sized game such as deer, black bear and even elk. This hard cast construction keeps your bore from being substantially lead fouled even after hundreds of rounds.
Since the average adult male's chest is only 12-14" deep in anteroposterior dimension, this ammo is an open invitation to collateral damage.
The description cites NYPD Stakeout Squad veteran Jim Cirillo's use of 38 Special wadcutters in his guns, apparently somehow equating these 44 caliber loads with Cirillo's loads, which is utter nonsense. Cirillo used standard soft lead wadcutters in his Stakeout Squad loads, fired at 38 Special velocity (700 fps or so).
Regardless of the advertising, these might be decent cartridges for hunting deer at close ranges. But WC's don't stabilize well much past 50-75 yards, so they're somewhat limited. And you don't need 24" of penetration to kill deer.
I've played with a bunch of big bore bullet weights and types over the years, and have killed a fair number of deer with them. I've pretty much come full circle, back to standard weight & velocity SWC or SWCHP lead bullets of moderate hardness. In the 44's I'd choose a 200-240 gr bullet at about 1000-1100 fps. That will kill just about anything I'd care to hunt in the lower 48, and the recoil & blast will be very manageable in the Model 69.
FWIW, one of my loads in both 44 Special and 44 Magnum revolvers is the old Remington scalloped 240 gr SJHP bullet in a 44 Spl case over 9.5 gr of U-Clays. Very accurate, very deadly load on both deer and bowling pins, yet light enough (and cheap enough!) to be an enjoyable plinking round.
