I just now picked up another 1911, a Series-70 Gold Cup, '78 vintage, mint condition. The deal sweetener was the H&G #68 200gr.SWC mold that came with it. The old boy swears that 4.0gr. Bullseye can't be beat in this gun shooting that bullet. I tend to believe him and can't wait to prove him right!
Looking back over the previous posts in this thread I note my comment regarding less than 100% feeding reliability with SWC's in my ancient 1911. I should have clarified that it has its original barrel which you may know is not chamfered at the breech end, it just has a tiny little feed ramp bottom center. Those relatively sharp edges the rest of the way around don't tolerate much ammo that isn't radiused from the bullet tip right down to the case mouth. Really hard taper crimping of SWC's helps a lot but still generates about one failure to feed in every two or three magazine fulls.
He's right about that load, it really is excellent. IMO, it's a good enough load (if that's the type of load you want to shoot) that it's worth having the barrel smoothed and tuned to feed them reliably. If you are inclined to do that yourself, the Kunhausen (sp?) 1911 shop manual has some good info on that.
