I have seven (7) Wilson 47Ds. Never a problem in more than 7000 rounds of 200gr LSWC handloads. The Ruger issue magazines (made by Check Mate) have "hybrid lips." They gave me double-feed problems with 230gr RN handloads. I've quit using them altogether.
I have 10 Checkmates w/hybrid lips, bought in a group buy off another forum. They work great in both my 1911s... No issues with factory hardball or the several variants of HP I've tried, and hundreds of rounds thru them. I don't yet handload, so no way to know. What OAL do you load your .45ACP to?
I hesitate to drag out this discussion because it went on forever on one of the 1911 forums a year and a half ago. In a nutshell, here's what didn't work and what went wrong.
Using LRN 230gr hard-cast bullets from Suter or Penn Bullets (they appear to use the same molds), the maximum COAL was 1.22". Anything longer, like the accepted optimum of 1.25", resulted in the bullet being jammed into the rifling.
When using these loads in Check Mate/Ruger hybrid-lip magazines, I would get a double-feed 8% of the time -- about every 12th round. By double-feed I mean a cartridge would voluntarily jump into the breech as the the fired case was being ejected, then the slide would try to pick up the next cartridge in the magazine on returning to battery. Two cartridges in the breech at the same time creates a cumbersome jam.
Also, as I stated previously, if I dropped the magazine, two or three cartridges would "squirt" out. I shoot in USPSA matches. I drop partially-loaded magazines 20 to 25 times per match as a matter of running the course. Squirting cartridges onto the ground is not acceptable.
Both Ruger and Check Mate worked closely and courteously on this situation with me. Both gave me additional magazines. And both admitted they had no idea what was going on. I really appreciated their perseverance and honesty.
Switching the 200gr LSWCs allowed me to load to a COAL of 1.25". This allows the cartridge to snuggle nicely between the front and rear of the inside of the magazines. Double-feeds became less common in the Check Mate/Ruger magazines and squirting cartridges from dropped magazines became less of a problem.
However, switching to Wilson 47Ds
completely eliminated both problems with cartridges loaded with LSWC 200gr bullets seated to a COAL of 1.25". (In fact, this load is listed as optimum in the pamphlet that comes with a 47D.) Additionally, LRN 230 gr bullets seated to COAL of 1.22" also work perfectly in the Wilsons, but I've standardized on the 200s.
I have more than 8,000 rounds through this gun now. I find it absolutely reliable with the Wilson 47Ds. I'm happy.
P.S. When first encountering problems with the Check Mate/Ruger magazines I ran a full box (100) of Winchester White Box 230gr through it. I had no problems. But, repeating,
I don't shoot factory ammo. Considering how much I shoot, there's no way I could afford it. So how the SR1911 and Ruger factory magazines perform with factory ammo is not relevant to me.
