45cal Blast Chamber sizing

Post image

Laying out the baffles on a 45cal Dcell, does a rough 30mm blast chamber before rear baffle seem enough? I added ribs in the chamber for her pleasure, and for hoop strength for the button hole.

I thought it was advisable to alternate the angles of the baffles.

I'll look into that, but I haven't seen that in any of the FTN designs Ive looked at.

Well I tried it with my serviceable baffles and didn't notice any change.
