LOL, dang Bob, it's a fine little cartridge.
1960 pre-64 model 70 heavy barreled varminter,
55gr ballistic tips 4125 fps over Varget, Lapua brass, CCI-BR2 primers.
Shoot a crow with that load inside 200 yards, all you'll find are a beak and some feet, maybe a wing blown off laying over there, it simply melts coyotes, never a twitch after catching one.
Back during the slow joe bidet kung flu plandemic, with Nosler also being out of stock, plus jacking their prices higher than a giraffes vagina, I bought a chit-ton of 100gr Speer Grand Slams for 9 bucks per 50, iirc some black friday no tax free shipping sale.
Worked up a very nice load in a 1956 pre-64 Featherweight Winchester model 70.
41.5gr Staball 6.5 powder sent those little Grand slams out at 3048 fps in new Starline brass cases primed with CCI-200's, light crimp in cannelures with Lee FCD.
This last April i was invited on a Red River pig hunt on the OK-TX border, one evening I got a 120lb sow to line up with a 200+lb sow, hit sow number one in the neck at 55 yards, the little Grand Slam exited her neck to hit sow number two in the ribs tight in the shoulder crease, that bullet exited the second sow clipping the rear of the offside shoulder.
Neck shot sow dropped at the shot, sow number two made a 25 yard death crash run, anyway you want to cut it, that's some bigtime performance from a small bore with 'cheap' bullets.
I'll use that nice carrying Featherweight 243 Winchester with 100gr Grand slams on whitetails this season without concern, any buck in the woods, quartering away last rib shot going in, he's in deep trouble and will be bleeding out/cooling off down at the low water bridge in very short order.
