Since I got interested in 200g .40s&w rounds, I thought I would ask if anyone has seen commercially available .45acp rounds that are heavier then the commonly available 230g?
Your estimation of 2150 fps, hopefully, is a missprint!!!I'm still waiting on my order, but according to the manufacturer, this is what can be expected:
990fps 435 ft/lbs from a 3.5" barrel
1050fps 490 ft/lbs from a 4.0" barrel
1100fps 538 ft/lbs from a 4.5" barrel
I'm shooting a subcompact with a 3.0" barrel so I would expect a muzzle velocity in the mid 900's. The 200gr rounds have the same fps rating as my 180gr HST rounds.
With the back pressure associated with the XD tactical, I would expect a muzzle velocity around the 2150fps mark with a 5" barrel. That's supersonic with with 60fps to spare!
It's times like this that make me wish I had access to ballistics jell...
Brad, There are no .45acp in 300 gr. You are missleading some new handloaders. You may have seen .454 casual loads in 300 gr but not .45 automatics heavier than 230 gr. Also .45 Colts are not loaded the same as .45 automatics, they can use a heavier bullet because some are used in carbines.I've seen 300gr .45acp.
If you are going to make a statement like the one above you need to back it up with proof. The thread you referred to has been discredited as far as loading .45 ACP with 300 gr bullets. Those 300 gr bullets were for .454 Casual not .45 ACP:shock:I have seen reloading data for 45ACP with bullets as heavy as 260gr. There pretty slow, 725-780fps.
There is very little chance of loading 300gr 45cal bullets in the 45ACP because once seated to standard OAL for 45 ACP the bullet would have been pressed down into the web of the case where the walls get thicker and likely bulged the case. There was a good thread on 300gr bullet in 45 ACP a few days ago.
Rambling (I have seen reloading data for 45 ACP with bullets as heave as 260 gr @ around 725 to 780 fps.)
First up I am the one of the poster in the last thread that said a 300gr is NOT possible in 45ACP. The 300gr XTP was designed for 45 Colt, 454 Casual and 460 S&W. I am the one the drew up and posted the picture showing a cross section of the 230gr FMJ and 300gr XTP in a 45 ACP case and why it would probably not work at least no while staying within the standard OAL.If you are going to make a statement like the one above you need to back it up with proof. The thread you referred to has been discredited as far as loading .45 ACP with 300 gr bullets. Those 300 gr bullets were for .454 Casual not .45 ACP:shock:
The XTP is probably the wrong choice to build such a load, they tend to have long bearing surfaces. I have a 285grLSWC (HP version weighs 250gr) that easily fits into a 45acp case, I have loaded them in my M625 rev. I don't think another 15gr would be "impossible", but certainly wouldn't be practicle.You based this drawing on a 1.256 OAL, when the max is 1.275. Not a big difference, but it just might keep the bullet from hitting the web of the case. Also consider some other 300 gr. bullets may be a little shorter.
While I still believe it is possible to build a 300 gr. .45ACP round, it is really pointless.
I don't think that anything over 230 is really worth while.
Sorry man, that is just not a true statement. As already stated, SPeer has had data for a 260grJHP for years. I have loaded 250grJHP for the 45colt w/ no problem. Recently loaded some 250grLSWCHP that are based off a LSWC weighing 285gr. They load & fire in the 45acp case. I shot them from a M625rev. because they feed poorly in a semiauto, & you can load them out a bit farther, no mag. They can be loaded to fit into a mag though, I did it to see if they would.:mrgreen:WARNING 230 Gr is the maximan you can load into a .45 ACP. :roll:
Heavier bulets are only for 45 Long Colt for revolvers and 454 .Casual
Do not attempt to load anything heaver than 230 gr (.451 diameter)for .45 ACP
GunDoc, Proof Accepted.... This is the type of backing up proof we all need to supply when posting on The Ammo Can where misinformation can lead to serious injuries. Thank You for the Link........250-260 gr. bullet loads in both lead SWC and jacketed have been around for years for the 45 acp.
John Taffon did some tests with heavy bullets in an XD a while back for AH magazine.
American Handgunner Taffin Tests
Tried and proven powders are:
Hodgdon UNIVERSAL clays
I would suspect that when bullet weights get over 270 gr. that you would reach the point of diminished returns with the oal limit and limited powder space available.
Hope this helps.
