Looking to play around with +p .45colt loads (a la buffalo bore numbers), and was hoping to find some FMJ bullets for .45 colt. Will be pushing the limits (1500fps) of plated bullets. Haven’t been able to find anything but placed and hard cast. Anyone have any tips on where to look? Thanks in advance!

I’ve been shooting some Hornady XTPs out of my Ruger Blackhawk and Henry .45 Big Boy, but only subsonic so far. No issues, but it seems to be a good candidate for 1500 fps. Often on sale. I’ve pushed Xtreme 255gr bullets up to 1200 (but no farther per their aviso) with no problem. -
I like the Speer 260 HP. The 300 is nice too. Don't know why I'd hotrod an FMJ.
Revolver or carbine? 1500 might be hard to achieve in revolver. I really think you're better off adding some weight.Palestine is a fake country

Try the Hornady 250 grXTP. They will mushroom well out of the rifle at 1500 or so. Not sure if they will remain intact beyond that. My Henry likes that bullet.
I have some 300 gr Speer JSP that I haven’t tried yet..might make a good pig round.Last edited by wbunning; 10-26-2017, 8:23 PM.Comment

I’ll read up on the xtp... everything I’ve read says the larger grain bullets get too long for the Henry and won’t feed. Some say don’t use anything over 300gr, others say it’s more like 275 that starts being a problem. Buffalo bore makes a 225 and a 260 with the speed and energy I’m looking for, but I was hoping someone made a Jacketed SWC or RNFP bullet for the caliber.sigpic"That's more suspicious than a nun doing squats in a cucumber field!"Comment

Haven’t slugged it, it’s a Henry Big Boy.sigpic"That's more suspicious than a nun doing squats in a cucumber field!"Comment

The bullets I’ve been reloading with are rainier plated, according to rainier they are .452, midway says they are .451”... they are in my dads basement where we reload so I’ll measure them tomorrowsigpic"That's more suspicious than a nun doing squats in a cucumber field!"Comment

Yes I was looking at Barnes xpb bullets for 454 casull (same diameter as the .45 colt version just 250 grains instead of 225), but was worried they wouldn’t feed in my Henry. The colt bullets are .812” long and the casull bullets are .909”...
I was reading some manuals and decided on either imr 4227 or 2400 for powder, depending on what I can find.
I have data for ruger/contender .45 colt so I’ll start there... 1500fps from 10” barrel should translate pretty well into 20” barrel, have a chronograph on the way to test it out. Looking forward to playing with it, some Buffalo Bore rounds go 2000fps out of 20” barrel, spicy! Thanks Scotty!sigpic"That's more suspicious than a nun doing squats in a cucumber field!"Comment

Don't get too carried away with velocity on pistol caliber carbines. A bigger chunk going slower is generally more formidable. You're never going to get going fast enough for hydrostatic shock.
That said, I'd go with the lighter (225 gr) bullet in a Barnes. The 300 grain Speer flat point has a upper groove to facilitate a shorter OAL. Works in my Marlin.
BTW, I don't see BB 45 colt cartridges going 2000 fps. Just a graph of external ballistics going that high.Last edited by JagerDog; 10-30-2017, 9:02 AM.Palestine is a fake country

I checked and I have some Speer 300 gr JSP bullets. I’ve yet to load them, but I took some measurements : Diameters are .450-.451, overall length is .760, length from mid cannelure to tip is .400.
Most of my .45 Colt cases are at about 1.270, so that Speer bullet loaded to mid cannelure would be at about 1.67”, just above the recommended max of 1.60. However, Sierra’s manual indicates OAL of 1.65 with their 300 grainer.
If you think you would like to try the Speer bullet, I could make up a couple dummy rounds and check feeding in my Henry Big Boy.
The Hornady XTP loads handily right at 1.600 and the Henry eats them just fine.Last edited by wbunning; 10-30-2017, 8:41 AM.Comment
