Those are ridiculously light. I think you're over reacting.

A #2 frame Parker will digest 2 3/4" 1 1/8oz 1200 fps all day long. Just buy what Walmart has available.

Hard to beat the Fiocchi Shooting Dynamics 1 ounce at 1200 fps for both price, performance and a gentle loading. Natchez has them on sale right now. Occasionally they offer $5 flat rate shipping or free shipping over $99. Keep an eye on their site.

Thinking it all through here. I don’t want to do damage to gun or fingers.
My 12 ga is a 2 frame
The 16 ga is a 1 1/2
Being a smaller gun I would imagine 1 1/8 oz would cause more pressure ?
Both guns are Trojans and are tight. Barrel wall thickness has not been checked.
Now that I’m getting deeper I was thinking of investing in the bench mic tool.
Would gladly share if I decide to get it.

Natchezss has free shipping on ammo over $250 right now.

I'm trying to be cautious with these old Parkers.
just received a chamber gauge from Connecticut Shotgun. According to the gauge, the Parkers I have are all 2 1/2 chambers. I was lead to believe that the one Parker that was stamped overload had 2 3/4 chambers and I was using 2 3/4 shells in that one. It was only with this new gauge that I was able to measure accurately. Is it unwise/unsafe to use 2 3/4 shells in a gun with 2 1/2 chambers? I know the shells fit just fine, but it is as they are fired and open up that the length of the shell exceeds the length of the chamber.

Are you sure they don’t measure 2 5/8, which are intended for 2 3/4 inch shells.

Looks to me like 2 1/2
2 5/8 should be halfway to 3/4

Yes that’s 2 1/2” and no, you shouldn’t use 2 3/4” shells.
They fit because the measurement of the chambers are for open (fired) shells. Open 2 3/4” shrells would NOT fit without pushing them hard.

That's what I was afraid of. Big difference in availability and cost between 1/2 and 3/4 shells. Also have a 16 ga chambered this way for 2 1/2 and this shells are out of stock. Looks like next step is to reload.
