I'm trying to load some .451 HP bullets made by HSM. Over 4.6 grains of Bullseye for my 1911. I set out for 1.23 oal, but it failed the plunk test, so I seated further until it marginally passed.
The bullets have pretty round shoulders and in order to fully chamber have to have an oal under the minimum = 1.16 inch.
Do you think that raises pressure to an unsafe level? Unless someone has experience that it is acceptable, I will pull the bullets.
Also, do you think these particular HSM bullets are just not right for my chamber, or am I missing something?
Thanks for the help.
