I am curious is anyone has chrono data from a 5” barrel for the following. It’s a 1911 GI
I shot my chrono which wouldn’t have worked on a 1911 regardless. (Magnetospeed)
230gr FMJ @ 1.240
4.6 gr tightgroup
4.8 gr HP38 / 231
5 gr HP38 / 231
My main curiosity revolves around perceived recoil. I shot 60 tightgroup tonight and 120 HP38@ 5gr. It’s a noticeably different gun with those loads.
Off hand the TG is snappy and maybe more accurate, but my accuracy went down hill later in the shoot.
The HP36@ 5gr is a nice soft shooting load and I am curious if they have similar ballistics.
Regardless, these darn 1911’s are dirty. I mean like nothing I have seen before with my plastic guns. I did a lot of scrapping and polishing to clean it up afterwards.
