1) Show me an old Norma round today- it's no longer around. The 10 is significantly downloaded. Even so- handload to it's former max, and I can easily exceed that with the 41 Sierra shows only 1100 fps with a 180 gr bullet. Remember the 41 is 1600fps plus.
2) the 41 can deliver 1000 foot pounds of energy with certain loadings. The current Federal 250 is not far behind. (If memory serves it's somewhere in the 1200's) Any 10 load is nowhere near that.
3) the load shown, the old Norma 170, is pitifull compared to a 41 giving you 1600 plus fps with the same bullet weight. Speer stops listing data after a certain velocity, saying the results are going to be 'explosive' and not wanting to keep going, even though there is more pressure within SAMMI left to go.
I quote, Sierra Number 3: JD Jones, noted handgun expert, "claims that the 10 mill is the equal of the 41 Mag in power are simply someone's daydream."
!!!!!!!!!!!!!!!
You and Spectre can cherry pick loads against weaker 41 loads to make a point that is no point. It is simply not rational. Any load you pick with the 10, I can beat with the 41 AS IT'S CASE CAPACITY IS SIMPLY GREATER!!
I own both. I love them both. But the 41 is a superior round. It has more case capacity and more power.
Where is this irrational need to believe in one's pet cartridge coming from? I just don't get it.
If the 10 was superior I'd say so. If the 40 SW, with even less case capacity was superior, I'd say so. You cannot negate amount of powder by nostalgia or quaint belief systems. Likewise, though the 41 is wonderful, and I even prefer it in many regards, the 44 is more powerful. The 44 has a slightly bigger diamter, can shoot 300 gr bullets, and is about 2O% more kinetic energy. It can be argued the warm loads of the 45 Colt in the right gun are superior to the 44- now this is a rationale discussion. The case capacity is greater, but the pressure less. They are close.
Yes, men can disagree. You can believe the 38 Special is superior to the 45 Win Mag- it is not true or rational, but you can believe it.
Here is a law of physics for you, take similar weights and bullet diameter's, load a smaller case to any pressure you desire, load a bigger case to the same pressure, and the bigger case will win every time.
10 mil case; .992 long, .423 wide
41 case; 1.290 long, .434 wide
Hornady has a modest little loading of the 41 with a 210 XTP at nearly 1400 fps and 1000 foot pounds of energy. It is not a barn burner. It could be exceeded.
You know, I could hot load a 38 Special in a Ruger Redhawk to beat some 41 mag loadings- it would hardly mean the 38 Special was a superior round. It only means if you handicap the 41 lesser rounds can beat it. Well, surprise surprise.
