I've been using the 200 grain SAECO/Redding #069 design (#H&G #68 copy) for many years. A light popular target load with 3.5 grs. Bullseye has been very accurate as well as 5 grs. for a full-powered load.
I made up some target loads recently using the SAECO/Redding #130, a 185 grain design (#H&G #130 copy). I've had the mould for more than thirty years, but never used it as much as the #069 because it wasn't very accurate when I exceeded target load levels, unlike the #069. My "testing" has been pretty informal and I'm going to do a lot more 25 yard shooting to confirm, but it actually looks like group sizes (not measured, just eyeballed) are a bit smaller with this bullet than with the #069.
While I had the pot warmed up , I also cast some bullets from the following moulds: Lyman #452460, Lyman #452488, and the RCBS 45-200. I haven't bought new moulds in years and I haven't used any of these bullet designs in a while, but loaded them with the best target loads from my old notes. All three shoot with reasonable accuracy, but none are really any competition for the #130 and #069. I knew that and I guess everyone else did, too, but I just had to try them again.
My Colts have both been accurized by Clark Custom and are capable of shooting very small groups, even if I can't come close to using them to their potential.
