.45 Wmag & .460 Rowland
- Thread starter Cal4D4
- Start date
I have two guns that I shoot 460 Rowland loads in:
A 20 ounce Patriot
A 15 pound Turkish Masuer in 45acp tight chamber
Starline 45 Super brass show no difference from ordinary 45 brass in threshold of
stretching or primer pocket growth. I have not seen any bulges in any 45 acp brass
yet.
I have only gone to 11.8 gr of AA#5 in a poorly supported chamber [Colt 1911], but I
have gone past 460 Rowland levels in a Patriot [pistol with good chamber
support].

5) Easy extraction ............ 185 gr 15.0 gr AA#5 1550 fps 20 oz Patriot
6) Case starts to stretch..... 185 gr 15.2 gr AA#5 1770 fps 15 lb 98 Mauser
7) difficult extraction ......... 185 gr 16.0 gr AA#5 1850 fps 15 lb 98 Mauser

Hey Clark,
Why don't you try a slower burning powder in your tests. AA#5 is quite fast and is putting undo strain on your guns with the pressure peak
, based on the loads you typed...
I have done extensive .45 Super research, and the powders of choice are ALL slower than AA#5. May I recommend:
AA#7
HS-7
Ramshot Enforcer
VV N-350
Blue Dot
Be safe...
YMMV,

I have tried as much 2400 and H110 as fits in the case. It just doesn't have the velocity of AA#5.
Power Pistol and LONG SHOT also work.
I have read that AA#7 is best, I have that and Blue Dot lying around. I should try it.
The limiting factor is not pressure, but recoil with my three pistols. The limiting factor with the rifle is pressure. I have to kick the bolt open.
I have shot 9mm at pressures way past human extraction. I think 45 acp may have the same potential.

2400 and H110 are too slow. Not enough case capacity. AA#7 is IMO the best .45 ACP/Super or 460 Rowland powder there is...
Having to kick the bolt open...
CAREFUL!!!
