There it is and the boolit that it came from. The boolit was fired into fine sand in my test tube - as I do - and I noticed this little sliver of patch on the base of the recovered boolit. Then I found another such sliver of patch from the next shot loose in the sand and had a closer look at the first. I then pulled it off and that's what I found!

This is the second sliver which was from a much faster boolit.

See what I mean about faster.

Looks like the paper rings I get when I load PP boolits to too high a pressure or use too fast a powder. Usually they stick to the end of the case and don't make it down the bore though. But then again I don't have a way to recover boolits like you do. Who knows - they might be out there!

[303Guy]

It's the bit that sits over the small rebate in my boolits. It was not the mildest load in the world so how it clung onto the boolit base is a mystery to me.

Here's another one - more tail and very obvious.

On the left is the base design I used and where the ring came from.

Those boolits were over groove size at the base and throat side of the bore yet bits of patch from between the rifling is still attached to the ring. (The bore is tapered).

Why all the worry about patch fragments? Is the load accurate? Does it achieve the velocity you are looking for? Does the bullet perform on game the way it needs to? If the answer to the questions is yes, what difference does the fragments of patch make?

Curiosity!:mrgreen:

I don't know yet if the boolit is accurate or not. I know it works on small game (turkey) and plan on trying it on ferral goat soon. The last time I shot the rifle it produced very good results (1¾" @ 100m/110yds) with open sights of the worst kind. I don't remember which bullet I used but it was 208gr - just not sure of the base design but I think it was the same.

303Guy, I get an almost remnment from the base of the 311-291. The twist and the patch on the gas check area stay intact. I don't see the rifling mark on the two grouve barrel but some of the others leave the nubs . I generaly find the strip about 10 feet in front of the gun. they are unwound reguardless of wether I wraped and loaded without sizing or from a rifle that requires sizing. I find it neet to find the bits and pieces and wounder about them. As the barrel polishes in the pieces are more uniform.

As the barrel polishes in the pieces are more uniform. That's an interesting observation!

I've just untwined this piece of mine and found it is the full width of patch - two wraps, and has seven little bits that fit in the grooves. It's a pretty uniform fragment.

I must have been mistaken about which patch style it came from. It can only be the 'tail-les' patch and the strip is the bit that covers the small rebate.

I gotta mount a scope on that rifle and see what it can really do! It's an original carbine barrel but not to that action.
