you who argue to never shoot shells longer than the chambers should provide data and actual research showing the results you champion.....
Joe, why you try to distort my words? Where did I personally say never shoot shells longer than the chambers? What kind of play is that? And I SHOULD provide data and actual research showing the results me champion...?
Go to h*ll Joe.
I personally used factory loaded 2 3/4" cartriges in some of my vintage guns with 2 1/2" chambers. But some of these guns such as Collath 16G double can't be used with 2 3/4" cartriges and I told why.
All data and actual research is in your hands allready. Longer shells develop higher pressure in short chambers. HIGHER, not lower or equal, but higher! This is the only data you have to remember.
All the rest are for experts and for people who knows a lot about guns.
Personally I won't take risk and tell Patriot 'Go ahead! Buy light loaded 2 3/4" ammo in WallMart and shoot it!" I didn't see his gun.
