I received the MP 452-374, 230 grain round nose with no lube grove. WOW what a nicely made mold. I cast a few pounds and did not tap the mold even once, they all fell out when I opened. But I have questions.
Bullets cast from the MP mold are .695" long
with a COAL of 1.270" for the MP mold so there is about .339" inside the case
-------------------------------------------------------------------------------------
Bullets cast from my LEE 230 grain tumble lube round nose are .665" long
with a COAL of 1.267" for the Lee mold so there is about .290" inside the case
The recipe that I used for the LEE bullets is from the LEE book @ 6.5g to 7.0g of 800X with a coal of 1.200" (Federal Large Pistol Magnum Primers)
the velocity difference between magnum and regular primers is slight and I have more magnums
I am using 6.6grains of 800X (at the low end)
What are your experiences / thoughts on the safety of the MP bullets at this COAL? I am concerned about how much of the bullet is in the case.
These will be fired out of a Hi-Point Carbine.
thanks
Francis
