That got me wondering... so I just looked at my reloading tables... with 170 grain bullets... I see a max loads of 2332 for .30-30 and 2283 for the .32WS... that's not a difference in favor of the .32WS. Admittedly, that's Hodgdon's LVR powder, and no loads are listed for LVR in the .32WS. That's not the norm... using like powders the .32WS is generally around TWENTY FIVE fps higher. Ballistically speaking... nada. Since the two cartridges are based on the same .32-40 or .38-55 case, are shot in rifles of the same make and model... that slight difference can be attributed to slightly reduce pressure as the larger bore diameter allows pressure to build less, that and the theoretical difference in area the pressure has to push against.cpt Dan Blodgett wrote:...If you look with equal bullet weights the 32 special is 100 FPS or so faster than the 30/30...
All three major ammo manufacturers list their difference with 170 grain bullets at 50fps in favor of the .32WS. And, of course, we all know that those numbers are right-on-the-money! NOT! Variances from one rifle to the next being what they are... I doubt even those numbers hold much water.
Sorry, since few of us are pushin' our loads at the max... (I hope), I don't see that as any great reason to get worked up over. Let me say it this way... I really don't want to be punishing any of my mdl 94s with 36,800psi loads. But, since my favorite weight is the 150, I can see I'm going to have get me some LVR powder... upwards of 2500fps with the .30-30 and 150s... that's pushing what I get now using RL-7 with Sierra 125HPs.
Stan, yep, .323 would be a better size for your .32WS, and pushing 'em that fast, they need to be hard and gas-checked.
