What was your load data with your cast bullets??? Were they 200SWC???
200gn SWC: 4.4gn of Bullseye
200gn truncated: 5.2gn of Bullseye
Contrary to what you have been told and you mentionned in your FNP 45 review, LSWC are EXCELLENT for 45acp and I have always had the best accuracy with them (over plated). They main advantage in shooting LSWC in 45 is that unlike the smaller calibers (higher velocity) I have found it causes less lead fouling. The only reason I do not used cast bullets more is they gum up the dies and they are not allowed for IPSC around here
Why production? Why not standard? If you shot it in standard you could at least score major. Is there such thing as shooting production major?
Because there is, as you said no major in production so you can load your 45 so soft it barely clears the barel... that is the theory. Also, the regular model has no safety so I would take my first shot in double action anyway.
That being said, that gun is +P rated and has a pretty strong recoil spring and there are no aftermarket springs available, so that 5.2 gn of bullseye is a near max load, just for proper cycling. Maybe my gun is not broken in yet, I don't know, but my 1911 and Glock21SF both used softer loads when new. So yeah I could've shot standard major, but it was just a temp rig, as I didn't know how long I would be working on my racegun (new compensator= find new loads + find new springs+ monitor with chrony)
