Hi,
If you use it for defense, I'd strongly recommend against using handloads due to increased liability issues if you have to shoot some thug and he lives.
His lawyer may have a real field day with you in civil court, claiming you deliberately cooked up some special and terrible load so you could gleefully go out and shoot some s.o.b.
MY RECOMMENDED DEFENSIVE ROUND FOR YOUR MODEL 60 . . .
I'm surely not being flip when I say that I'd recommend you purchase a few boxes of various makes and weights of premium self-defense ammo and see which one your particular specimen shoots best . . . and to perfect "point-of-aim!"
With you being a fellow handloader I'm sure you understand quite well already how different loads shoot to different locations on the target.
IIRC, many of the earlier J-frames came regulated for 158 grain ammo and, if yours prints best with this load, buy it!
There's a lot of buzz lately about some new "Short Barrel" defensive ammo that comes in, I believe, 130grain hollowpoint. If your piece shoots to P.O.A. with 158 grain ammo then the 130 stuff will probably shoot lower.
I just picked up a new (for me) 1964 Model 36 (no dash) in factory nickle and, believe it or not, it shoots even better than it looks. I'm hoping to go tomorrow night and start my own self-defensive load selection by letting the gun do the "talking" on paper, so I'm in the same boat you are!
So far, I've run about three cylinders of 148 gn. wadcutter through it, including one single action cylinder, standing and unsupported at 10 yards. NOW I've got to find THE defensive load that shoots to the SAME point-of-aim! I was NOT expecting this out of a snubbie, although I do expect this out of my larger wheelguns . . .
I'm a much bigger proponent of shot placement of a self-defense round vs. a specific factory-hyped hollowpoint that goes somewhere else!
RECOMMENDED PRACTICE LOADS . . .
1. Whatever shoots to the same p.o.a. as your defensive round, if possible. Or . . .
2. .358" diameter, 148 grain lead wadcutter bullet, over 3.3 grains of Unique with a Federal small pistol primer. Federal primers work best with all revolvers, especially those with lighter trigger pulls and custom race revolvers that might need to go bang with a lighter firing pin strike!
GOOD, STOUT SELF-DEFENSE HANDLOAD . . .
158 grain, lead hollowpoint (LSWC-type) bullet over 4.7 grains (max.) of Unique + Federal small pistol primer.
Hope this helps!
Tom
