What were you guys recommend 10mm 40 Super or 45 Super?

[BJung]

I only know of the 10mm and will go with that because brass is more common, I can shoot 40cal through it for fun, or even switch out the barrel for 357 Sig using worn 10mm brass resized.

[huntersdog]

Also, if you do decide on a 45 cal build, this is an excellent little bullet and the mold is fairly inexpensive. It's only .528 long, it has a .325 meplat and if loaded to 1.2 oal(which will require a throated barrel) with power pistol or longshot it will exceed 10mm and not even be a +p load.

It's the lee 452-200rf

Can I ask what your lead mixture content is for the Lee 452-200 RPFP to get the hardness and do you lube or clear powder coat them?

I was looking at buying some mixed lead from Roto metals or just buy the products from them and just mix it myself to get started as lead is hit and miss locally.

10MM is a good choice and is enough cartridge for anything in North America, except maybe bison.

I use around 17lbs of coww and add 1 pound of monotype. I'm not sure what to call it other than a mongrel alloy. I think it close to 4% antimony and 1% of tin. I do powder coat them with a dark grey that is not represented in the picture. I also quench them straight from the oven after 30 mins @425, don't know if that's actually doing anything, but it does allow me to handle an size them right away.

10mm……for a semi-auto.
Something bigger in a Revolver.

[Ghost23]

I just had 200 rounds of 10mm loaded with 180 xtp at 1300fps. Probably get a bit more fps out of my 7"barrel. Can't wait to hunt with it this season!

I have about 500 speer spp cases and due to the price of lpp's, I'll be using these for a while to save the others for 45 colt. Which isn't a bad thing. I used the south American primers for this load.

Very consistent, maybe .4-.5gr more will match the longshot load.

[DMC707]

I voted for the 10mm (and have voted with my wallet a few times over) ---- would even stick with a standard 5" barrel over a longslide -- handles better (for me and YMMV)

[elmacgyver0]

None of the above.
Not because they are not good, just because I don't have them.

[david s]

Voted with my wallet also, I tried to like the Glock 20 but failed so went with the 10mm in a 1911 platform. The 200 grain at 1200 fps load supposedly will wear out the 1911 eventually so it's a pair and a spare set up. A couple of Kimbers and a Dan Wesson. The three should see me out any way. Still not sure the 10mm will beat or even equal a 41-44 or 45 Colt, but my arthritic hands say this is about all they'll stand for. It's always nice to have options.

[murf205]

As far as keeping it simple, I gotta' vote for the 10mm My son bought a Colt Delta Elite and I ordered a Lee 170 gr TC mold and a 40 cal push through sized die. Powder coated with a dab of Blue Dot and they wad up in about 2 1/2" at 30 yds with my old worn out eyes. Nuttin' to it! You'll love it.

[chunkin lead]

10mm is my choice. I like my Kimber 10mm.

[Tracy]

If I were going to hunt with an autoloader it would be a .45 Super. I have a G21 that I converted to .45 Super and I would either use that or build a 1911. .45 Super is capable of more power than a 10mm is capable of, and I am very comfortable with the ability of a .452", 255 grain bullet with a large meplat, traveling at 1000-1100 fps to get the job done. It's capable of more than that too, but that's about what I load mine to.

In reality though, I prefer to use one of my .44 Mag, .45 Colt or .454 Casull revolvers for hunting.

[R-71]

10 MM, Most gun shops will have a box or two available which might make the difference if your ammo is lost or misplaced while on a hunt. I'd probably go with a glock 40 for a strictly hunting gun to get the most out of the cartridge.

[jonp]

I voted 10mm but the upside of the 460 Rowland is that you already have a firearm in all likelihood that just needs a simple conversion so if you have one you are comfortable with it does make sense to go that route.

[Sandspider500]

That's a strong brew. I wonder how many voted 10mm only because they have one.

[Boerrancher]

I voted the 10mm because I own one but I also have a P220 converted to 45 Super. The 45 super pushes a 185 gr JHP at a hair over 1309 FPS (actual chronographed speed) and the 10 mm pushes a 1312 FPS (actual chronographed speed). Those numbers were the average of 10 shots each. There is not a dimes worth of difference between the two. The 45 Super may hold the advantage over the 10 mm with heavier bullets but but as we all know in a handgun and bullets weighing 160 gr and up speed is the name of the game for killing, but for killing what?

I am more concerned about reliability and accuracy than anything else. A 460 Rowland is nice, but if you can’t manage the recoil, and to be honest most can’t, or it jams up it is useless. I’ve personally been in enough gun fights to know and understand that the best gun to have in any dangerous situation is a gun that you can shoot accurately, and it works every time you pull the trigger. You’re better off in a dangerous situation with a Ruger MK II 22 LR, if you can shoot it accurately, than you are with a 44 mag that you can’t hit a human center mass with every time at 25 yds due to the recoil. Same applies if you are carrying it as a bear gun. If you can shoot the eye out of a squirrel at 25 yds with the 22 but can’t keep them all in a 12 inch circle at 25 yds with a 44 mag, you better off carrying the 22 as your backup for a bear attack.

I’ve had lots of folks think they were pistol shooters until they took my combat pistol course which applies to bears as well, and especially when they were put on the shooting simulator with their firearm under the stress of an actual attack. I am not a great pistol shooter. Never claimed to be, but I understand the reality of danger very well and people not having the right gun, or the proper training and conditioning to deal with a violent attack be it from the 2 or 4 legged variety.
