I've been enjoying the heck out of 170gr Keith in 38 Spl brass, over 5.3 gr Unique, for 1000 fps in the Security Six.

Thanks for sharing that load Shane. I recently bought one of those 686 Plus 3" 7 shot revolvers that Shrapnel posted on here last year. I just started casting that 170 gr Keith out of a new Lyman mold - I'll have to give that one a try...

Jerry, it's a mild shooting mid-range load in the Security Six. I ordered the 170's from Western Bullet Co. in Missoula, and they are from the Lyman 358429 mold.

QuickLoad predicts pressure of 21,600 lbs-psi. That puts it above 38 Spl +P level of 18.5K psi, but well below 35K psi of full house 357 pressures.

That sounds like a perfect combo and makes sense - Lyman #47 shows 5.0 Unique as max for the 38 Spl with that bullet at 860 fps. My mold is also the 358429 - my thought at the time I bought it was a heavier bullet in 357 cases at 11-1200 fps.

Just finished rolling a few with Unique at 4.7, 5.0 and 5.3 in 38 Spl cases...
