I did not get a chance to chrono those loads yet in my G29. However, the same load in McNett’s G20 with a 6” Barrel is getting 1380fps. I would think that the same load in the G29 is probably getting right around 1200fps. I am not sure what the velocity is with the G30 and 265gr Castperformance. I will need to chrono those along with the G29 to find out for sure. I went to the range this past weekend with the intention of using my chrono to gather some data. Unfortunately, the weather wasn’t too great.
According to Alliant Powders under the 45acp section, a 260gr JHP with 8.3gr of BlueDot will do about 780fps out of a 5” barrel. I used 7.0gr as a starting point with the 265gr in a 45Super Case and worked up to 9.0gr with no noticeable pressure signs from both my Glock30 and 1911 (substituted with 250 Keith). Warning: I only guarantee these loads to be safe in my guns. As always, start with a reduced load and slowly work up.
The .401 Beartooth 200gr FNGC @ 1300fps out of a 5” 1911 is quite impressive. I sure wouldn’t feel under armed with 8 rds of those in a 1911. I believe McNett was able to get something like 1460fps!!! with the same bullet out of a G20 with a 6” Barrel. BTW, I was able to get a 135gr Nosler JHP to 1750fps with my G20 with a 6” barrel.
My current sidearm is the G29 stocked with 10rds of Beartooth 200gr FNGC. It is ideal for me because it is compact, lightweight, and still packs 10rds or respectable whallop that will penetrate really well. As a matter of fact I will be heading out for a Boar hunt tomorrow morning with my partner. Will be bringing my Marlin 444P Outfitter and my G29. Who knows, if I can get close enough I may try to take Mr piggy with my Glock. Wish me luck J
