Your no dummy. Ways to a wound channel: bullet design, velocity. Why am I not on the 230 grain ball bandwagon? It was a committee trying to get something to work like the 260 grain Colt FLAT POINT, IN .45 COLT, @ 950 fps.
Remember, Browning came up with 200 grain FP's, at about 950 in the original design of the .45 ACP.
If I'm not carrying .45 ACP HP's, I'm looking at 200 grain Flat Points, at 1200 fps.
My .45 Acps are setup by Jack Huntington, and timed to shoot 45 Detonics level loads. I think Browning, later improved by Detonics, had it right.
With the added velocity of the .451 Detonics, 200 grain speer flying ashtrays @ 1200 fps, and 230 grain HPs at 1100 fps over came the problems with the .45 ACP HP's.
I'm warm and fuzzy on penetration, and, I've shot nearly 500k rounds of 200 grain speer flying ashtrays at 1200 fps. Detonics supplied evidence of their effectiveness when used by law enforcement, and, at that velocity, you get a large wound channel, even if the bullet doesn't work.
If I'm going into a really bad part of Richmond, or Oakland, where you have huge bad guys, buffalobore's 260 grain .45 ACP/ .45 Detonics/super flat points would be my friend, or, going into hog country.
I don't think much of RFN's, unless they are in a .510 Wells, and weigh 600 grains, at 2150 fps, or .458 Lott, and 500 grains at 2300 fps:
Heck, they are even flat pointed as much as they can..
On the otherhand, the above guns shoots .510" Caliber bullets. a 525 grain, RFN, at 1350 fps would probably get the attention of everything on the planet. Anyone want to test fire those rounds, with 60-82 ft-lbs of recoil?
I've got a bunch of 525's loaded at 1350 fps, that sit in a box while I shoot Linebaugh 'short' at 1100 fps...with lighter bullets, like 350 grains.
