The stock breech is about .691, so a little wide, but the FS rounds hold themselves in place with mag tension and feeding should be ok. You might have trouble pointing down, since the chambered FS round will want to slide down to the smaller barrel diameter. At least it should stop there. It would show up as reduced velocity.

Are we sure that slight of a movement would change things much at all?

Field testing!

The stock breech has about an xxxx available to reach the barrel, iirc. ***actually, looking at my own pictures, it is only 1/4" or so on the stock breech. I was thinking about the one I made.***

My worst velocity variations on pumps and round paint have always been associated with paint moving away from the bolt (-100/+0 fps). The worst was a superbolt where the barrel was 1/8" from the breech. Maybe the air was just bouncing around that groove, but the Nelspot also does badly if you let a ball roll away from the bolt face.

You should try a tight fitting ball halfway down the barrel (and not). I've dinked with it, putting a ball a few inches down the barrel, and promptly went looking for a tighter barrel, or moved my high dollar chrono station off the top of the grill so that I could shoot upwards without hitting the neighbors house.

I never pulled the nelspot barrel off to see how far it was rolling before I shot. It may have been large variations.

I was thinking about ramming ~10 balls various dinstances down a barrel and see how velocity is affected. I know it will go bad at some point, but curious if it happens the instant it 'rolls' away from the bolt, or it it takes 3/4/5/6/7 inches.

Read that in this guys voice and keep from laughing, no, seriously.
