So, SPeer also uses the 5" Bbl. len. - I this isn't to
give the .45 ACP cartridge advantage, but just as DT does
the company presents to information to the largest
percentage of platforms on the market for that cartridge
which is why they're using 4" for .40 S&W and the 9mm Luger
cartridges.
* Some say DT doesn't load their .40 S&W as hot as other
cartridges because the company started off loading
10mm Auto to full power loads. That a company might
do this could be backed up when you look at Cor Bon's
10mm Auto offerings, who some say are watered down
because Peter Pi & the Company wants to promote the
.400 CorBon - draw your own conclusions.
I don't classify, Double Tap, Buffalo Bore, CorBon as
Hand loads.
Anybody hear of the new Buffalo Bore offering in
.45 Auto Rim? 200 gr. SWC @ 1200 FPS talk about HOT!!!
FWIW - I have .45 Auto RIm with new Starline cases and the
Leadhead 200 gr. hardcast cusom load on m y spec. to
1,-25 FPS by Reeds Ammo & Research Oklahoma City OK.
In my 625 5" Bbl. 45 oz empty, it has a bit more recoil than
WWB 230 gr. JHP.
