I'm working with two of my senior students building a Universal Receiver for pressure testing. Have purchased an unchambered .451 Shilen pistol barrel blank and want to chamber it to .45ACP/AR. Plan to test this cartridge w/heavy-for-cartridge cast bullet loads, i.e. loads with 250-270 gr boolits for potential revolver use.
Does anybody have a drawing for SAAMI spec chamber dimensions for this cartridge? Or can you refer me to a source for same?
If necessary I can make the appropriate tooling/chamber reamer for what is essentially a straight wall case, and I'd like to cut chamber size and throat angle/dimensions to standard specs. I want to avoid any further unnecessary expense and I can also use this as way to teach students a little more about making/heat-treating special tooling.
Of course, if someone has a chamber reamer they would be willing to loan out for this educational project I would be glad to give my word on guaranteeing it's proper use and safe return.
Any help would be greatly appreciated. If project works out I will certainly share results here. Thanks in advance for your help.
