458 SOCOM reloading problem > AR Variants

Posted: 9/29/2010 6:58:14 PM EDT

************Cross-posted under AR-15 Variants, thread AR Big Bore and the reloading section********************

I am using a Dillon 550 and have a Redding 2 die set # 80444. I am developing a load using a Barnes 300grn TTSX bullet and am TRYING to seat the bullet for a COAL of 2.240-2.245

Heres the problem, my seating stem is ran all the way down and the thumb lockring won't engage (lockring free-spins because the seating stem threads are below where the lockring sits and can't engage the seating stem threads). It's like the seating plug is not long enough. I might have a die problem. TBD, will start the phone calls tomorrow to Dillon and Redding.

also looking for load data on IMR-4198, H110 and the 300grn TTSX, Starline Brass, WLP.

Thanks

I had the same problem loading Hornady 325 gr FTX
Give redding a call and they will send you a longer seating stem.

FYI, all current production Redding .458S dies ship with the longer seat stem. Only the ones that came out at the beginning shipped with the short stem. I think they thought people wanted to seat 405-500 gr. bullets a lot more than they do.

Called Redding and they are going to send out another seating stem with the number 36 stamped on it. The seating stem I have is currently stamped with a 5.

Just in case anyone else runs into this........
