Dale53,
Your killing me!!! I've been looking for a 631 for years. I've got a 63 and a 60-4, both are constant companions. The worst part is I used to work nights and evenings while I was in the Army, at G.A.T Guns in Hanover Park, Il. (now Dundee). I believe the 631 came out in 1984, and was a hot item at the time. I'm sure I handled at least fifty of them. Having a young family and into large bore pistols at the time, I just didn't get one. I really started looking for one about 1990. It's on my bucket list.
I'm shooting snared beaver with a .32LC load in my .32 mag,4 5/8", Single six,at 680 FPs, with the Hornady 85gr HP bullet. The RCBS 98 gr., at the same speed, exits most beaver, and a .22 lr leaves them flopping on the bank making a mess, with little hope of a reset at that location. The Hornady is Bang, DRT, in the water, no mess, reset, no exit hole.The Hornady's are hard to find and not cheap. I just purchased the NOE 314366 in an RG4, 2 GC 2PB in al. Figure on using the GC Fp in my .32-20 and the PB HP in the .32 mag. I'm pretty confident I can match the performance of the Hornady with this mould. I'm hoping to get the same accuracy as the RCBS.
