.458 SOCOM OAL question

[D. Hargrove]

Running the following, looking for the MIN OAL acceptable. Looked everywhere I could thing of and after countless hours of experimentation have resorted to asking OSA.

500gr round nose hard cast
24gr of Reloader 7
light to no crimp
2.25 OAL

bullet is hitting lands and failing to feed for that reason. At a OAL of 1,905 the bullet is just shy of the lands and feeds nicely. Question is will a OAL of 1.905 cause pressure issues with the round? I appreciate the assist folks.

You get pressure rise when in the lands you also get a little rise when you seat the bullet deeper into the case.
If you are not at max charge weight I would not sweat it.

I do not load for that round so i can't know what max charge weight is.
I have seated my bullets in other guns all over the place and never seen really much difference in pressures.
Not enough to worry me anyway ..But I was not at the Max charge weight either

Thank you, i am nowhere close to max charge. I will do a test firing tonight.

Yep. Just watch for telltale signs of excess pressure and test fire away!

You will never see pressure signs in that low pressure round.. if you ever do you are way over .. as I think it is 35,000 psi rated.
I never see pressures in my 45acp even with 230gr running at 1200 fps. YOu know that is speedy for that round.

What platform are you shooting? AR? I got an upper a few weeks ago but have yet to put on lower to see what it will do

AR, i figured out the issue as I was shooting a 500 grain round nose that regardless of how deep it was set in the brass would jam the lands. The solution is a Lee 459-500 3R mold. I should have it saturday and will post results.

Awesome, keep me updated.

Ogive of the bullet was too sharp is what I'm reading. Your going to a more pointed bullet?

Probably won't help you much since these are 325gr. but was able to avoid crimping since the tip flexed and the loads were fairly light. Never had a bullet move due to recoil. Will probably be a different story with the 500gr.
