Use An Accurate .45ACP Load Eh1
As above, use both an accurate and "up to velocity snuff" .45ACP load.
That said you DO need sufficient and regular velocity to get ACCURACY at the 50 yard marker. Unless you chronograph a number of shots you will never know just how accurate your loads could be. I was always amazed as to how some loads varied in velocity and others have very little variation.
I have shot both my "utterly stock" Colt Government 1911A1 .45ACP in PPC Matches not exceeding 25 yds (indoor PPC) and my Colt Gold Cup outdoors in Distinguished at the 50 yard marker. My pick was either the 230 grain bullet (UTTER Reliability) and an "accurate load" courtesy of any number of loading manuals and/or the 210/185 grain SWC/Truncated Cone type. the SWC cuts the full calibre hole which does eliminate all that eye squinting and use of overlays again and again when a 60 shot target is scored.
The
WWW.CPCA-PPC.CA site has one thread just on this topic: Accurate 45CAP loads. The "really good news"is that the 45ACP has had a LOT of load development. The NRA has a BOOK just on ACCURATE loads for the 45ACP.
I agree with Popurhedoff; use at least a 700 fps or more load with an adequate size bullet verus reducing powder charges or using spring changes. IF the recoil seems excessive well thats why there are 9mms!
My pick would be 6.3 Unique with very good 230 grain cast bullets or the 210SWC or 185SWC with a sutiable charge of 231.
What I mean here by "very good bullets" is that some bullet casters are better than others. Try weighing the cast bullets or even examining their bases for voids or examining the sizing. Then try experimenting at 50 yards shooting from rest to see how well you can group or IF really daring use a Ransom rest.
Even simplify further; skip the Ransom rest and months maybe years of 45ACP load development for Match Loads. Just get some Remington Match or Winchester 185 grain Target loads for competition and shoot your reloads for practice. Winclean Target loads are relatively inexpensive given how much 45 ACP cases now cost just to reload.
10 cents a 45 case, 3 cents primer; 2 cents powder, 6 cents a bullet = 21 cents at least a load plus TIME to properly assemble eh!
Currently Winchest TR 186 grain loads sell for 30 cents apiece and you get to keep the case eh! Think of it as a dime a shot to start in "already loaded terms".
Factory loads seem to have a slight edge or is it HUGE edge in terms of 'always working"..chambering sizing case length and very few squib loads!
Unfortunately using factory ammunition removes one valid excuse such as "Woulda won the match except my reloads malfunctioned eh!".
