Cat Modernization

[Myrkul]

I understand beveling the bolt on top to avoid clipping but wouldn't the rest of the bolt encourage pinching any shells between the bolt and body?

There is nothing indexing the bolt in these. It's very conceivable that the front delrin portion might spin slightly after a couple thousand cycles. Even with all the mods, the re-cock becomes extremely unreliable if you have a single ball break in a cat, so "shooting through" a chop isn't really an option anyway. At any rate, last time I tried shooting 0.675 paint through a cat, I never made it out of the staging area. Today I put at least 4 or 5 hoppers though it. The whole point of this is to make sure there AREN'T any loose shells in the breech....

Shows how much I know about cats!

I wonder if a T15 bolt would fit in a Cat. I know it's based on the design. Obviously the slider doohickey would have to be swapped for the donut.

You might just be able to take the brass tip and swap it with the derin from a cat, but I suspect some of the dimensions will still be off. That is also going to be far more expensive then the two $0.15 washers and a sheet of 400 grit sand paper....

Great mod. Put about half a case through my thundercat at bones n' ashes a couple weeks ago by modding my bolt in this fashion.
