Loading 10 Ga vs 12 3 1/2"

Can a 10 Ga be loaded to more velocity than a 12 Ga. 3 1/2"? I am still trying to decide if a Browning Gold 10 Ga or a Super Black Eagle is in my future.

I would guess in a modern 10 that it would win. Both push the same load of pellets.
 
Well according to Alliant's web page basically your bigger loads (1 1/2 and 1 5/8) do have more velocity in a 10 Ga versus a 3 1/2" 12 Ga.

Anyone else have some opinions on this?
 
Velocity in shotgun loads is an arcane and complicated matter.

A "Magnum" rifle load is one where a standard projectile is moved at higher velocity than a standard rifle load will. Contrast a .308 vs a 300 Mag.

OTOH, a "Magnum" shotgun load is usually moving at a standard velocity but with a heavier payload, like 1 1/2 oz vs 1 1/4.

How about describing the mission? 10 gauges are used for turkey and waterfowl,mostly.
 
New info since original post........

The mission would be just that turkeys and geese. I bought a used Super Black Eagle this last weekend so I am going to come familiar with 3 1/2" 12 GA. 10 Gauges are interesting though.
 
Kobra, do yourself a favor and try out some 3" turkey and goose loads. Pattern them, and then try the 3 1/2" hernia inducers. Chances are, the 3" patterns will be better, but you will not know if you don't try them.

If I needed to use barnburner loads, I'd be getting a Mag 10 Ithaca and patterning heavily. BTW, the few times I've shot a Mag 10,it worked well and kicked little. An 11 lb shotgun, true, but sturdy,reliable and effective...
 
I am one step ahead of ya...

I bought some 3" last week before the Benelli purchase to feed my 870 Express so I will be able to use it, until I locate some 3 1/2" (Turkey season just started in KY so the stores are temporarily out). I planned on shooting them and testing my 870 with them too. I work as an engineer so it is in my nature and mentality to screw with everything I own looking for that perfect combo.
 
Ok, Kobra, I understand engineers. Why not pattern both your shotguns with what you have and see if the results are satisfactory? You may have the right combination now, just waiting to be discovered.

And, play with the chokes also. Sometimes better patterns come with a bit less constriction...
