88 TMK Loading Thread

[mwoolsey5]

Apologies in advance, I’m a complete amateur when it comes to hand loads and reloading still, but trying to learn. I plugged everything into an ai tool, but could someone verify I have the correct COAL length before I load some of these up.

Hawkins Hunter DBM Short

Hawkins website says the Hunter DBM short magazine has an internal length of 2.880”. AI tool says the ideal length is 2.65-2.75” to touch the lands, but that I’m limited by the magazine and need to have a COAL of 2.5-2.52” to ensure smooth feeding and that the tip doesn’t drag in the mag. Does this sound correct or should I be loading up a dummy round at the longer COAL length to see how it see if it fits the mag and/or feeds well?

Do you have the magazine on hand?
Make a dummy round of your chamber, and see how it fits in the mag.
