I recently bought a couple of boxes of Buffalo Bore .45 acp+p loads with 255 gr bullets. The nose looks almost exactly like the Laser-Cast 250 gr bullets I load for my .45 Colt revolvers. I would like to know what powder to use in that restricted space when such a large bullet would be pushed in past the normal crimping groove so the .45 acp rim would head space correctly.

I use Unique for loading the Lyman 260 grain bullets in my 45 Auto Rim loads.

I also use unique in the 45 ACP with a 255 RNFP Lee. I taper crimp behind the crimp groove as the nose dia is .448 in front of the cg. The OAL works in the 1911. However if you have a Sig, they require a more deeply seated bullet as the mag length is shorter.

Speer has data for a 260 gn jacketed bullet in the ACP. Unique is one of the powders listed, as is Herco.
Lee reloading manual has listings for HS 6 also.

OAL is one concern, the other is the bullet heel swelling the case as it contacts the web. You might find it necessary to use a bevel base bullet if your firearm needs a shorter cartridge oal.

Thanks. Unique is the powder I use the most.

Forgive my ignorance but does one gain enough performance to make it worthwhile.

I'm guessing on can hold mid 800s and get the performance as a result of the extra weight, after all momentum can do some wondrous things.

Does one have to step upt the recoil spring a few pounds?

TCLouis,
ARE you asking about shooting heavy loads in a model 1911? If so yes you can change to a heavier recoil but there is more to it than that. With a heavier spring the slide velocity will be slower during recoil but higher when the slide is moving forward thus battering the locking lugs and the lower barrel feet.

To lower the slide recoil velocity you maybe should also consider a heavier main spring and also an over size EGW firing pin stop.

On the box, this +P load is listed at 925 fps. I assume this is with a 5 inch gov. barrel, and I would lose some out of my 4 in. XD. If it is around 900 or a little less, it should still be potent hog medicine. I would like to replicate this load myself so I could afford to practice as these loads are a bit pricey.

I shoot a 255SWC hard cast out of my P90 at 875 using Herco. From what I have read I could have went into the low 900s. but I gave up long ago pushing things to hard.

Buffalo Bore uses bullets supplied by Rim Rock Bullets. You can purchase them directly from Rim Rock. I do not have any BB bullets to check, but I have a couple of varieties of the heavies that are sized .451 from Rim Rock. They make seating a little easier as to the diameter, OAL and web of the case.

If you dig a little on the BB website you can get info on the velocity and guns used for the published velocity numbers. Tim tests with his guns, not long pressure barrels, so his box printed velocities should be pretty close to your gun.

I have shot Buffalo Bore ammo in several different calibres, and several different loads in the same calibre.
I have found it to be Excellent ammo.

I can also say that Garrett 44 Mag and his 45/70 ammo is also excellent.

I can also say that Cor-Bon handgun ammo, and his 45/70 ammo is also excellent.

Just make sure when you buy any of these guys ammo you are buying the right ammo for your particular gun.

My heavy 45 Auto Rim loads go through a revolver. I shoot "stock" loads through the pistols as I have not changed up the spring systems in them and have no desire to do so.

Power Pistol would be an excellent powder for this application IMHO

I have to agree, the hassel of setting up a 1911 for only one load, which then makes the pistol unusable with standard ammo, is a decision that has to require some thought. Wolff does supply the firing pin springs and recoil springs as kits. I like "revolver only" loads in S&W .45 ACP revolvers, exceeding standard .45 Colt load, up to 23,000 psi, 200 JHPs at close to 1200 fps, 280 grain cast at 900 fps, all possible with Unique and similar powders. The dedicated handgun issue comes up with .45 Colt/.45ACP Ruger Blackhawk too, lots of effort to properly set up the gun for one specific .45 ACP load. One gun, one load, less issues, at least for me.

Shooting the Buffalo Bore 255 grain hard cast does not require any special set up. I have a 1911 set up for 45 Super and it will still function properly with standard 45 ACP loads. Pressure affects slide velocity, not bullet weight.

I fired the Buffalo Bore 255 grain hard cast +P load in to 9 one gallon milk jugs filled with water and exited all 9.

Many people claim that handguns are useless for protection against bears. Numerous examples have shown that this is a false notion. Handguns may not be ideal as defensive weapons for bears, but they can be effective. In a defensive situation, you have to use what is available. In this case, a homeowner in Alaska used a .45 against a brown bear that was trying to get into his house on July 7th of this year. He and his son were in the home. He had scared off the animal with some warning shots just three hours before. From adn.com:



“I couldn’t believe that it came back,” he said.

Landess grabbed his .45 pistol, stepped out onto his upper deck, took aim and fired seven rounds toward the bear’s vitals. He said the bear “got crazy” and ran about 50 feet before it collapsed and died.

Landess said while he has seen bears around his property, living in close proximity to the Kenai National Wildlife Refuge, he had never experienced one this aggressive. He said he didn’t have any food around his house that could have attracted the bear but did have an empty cooler on his porch that the bear tossed around along with some chairs. He said this was the first big game he’d ever killed.

“I’m not a hunter; I’m a fisherman,” he said. “It wasn’t something I wanted to do. I wanted to scare him off.”

A comment by Landess' son on ADN.com gives us some more details: The pistol was a Hi-Point .45, and while seven shots were fired, only one shot hit the bear.

Yes that was my dad and he shot it with a highpoint 45. Shot at it 7 times but only one shot hit in the directed area. One threw the lung dropped it.
This appears to be another case of a bear that became too acclimated to humans. It associated humans with food, and so it became a serious risk to human life. Use of firearms as a defensive tool against animals is fairly common in the United States, though it is more common against an aggressive raccoon or a rattlesnake than against bears. No one knows exactly how many times a year guns are used defensively against animals. My personal observation is that in rural areas, defensive uses against animals, whether to defend life or property, are more common than defensive uses against people.
