Got a new Dan Wesson RZ 10

[DeanC]

so I will wait patiently for SS and a few others to chime in.

You probably can even just use 40 brass and load long.

I would love to hear a veteran reloader's take on this. I would assume that the two cases are designed for entirely different pressure spectrums, not to mention other physical differences between chambers and could present some interesting dangers if experimented with.

Then again I don't know, not having reloaded for either of them, so I will wait patiently for SS and a few others to chime in.

Sounds fishy to me. I was under the impression that most SA cartridges headspace off the case mouth. Short .40 case in a 10mm chamber sounds iffy as there'd be a gap between the case mouth and where it should headspace.

Think I'd rather take a 10mm case and load light, than vice versa.

But, never tried it, not sure I'd want to try it, will wait patiently with popcorn and blast shield at the ready.

Isn't the 10mm case like a 1/4" longer than the .40? That's way too much difference to be swapping brass in an auto - and I hardly know the first thing about reloading.

Yup. That where many my concerns stemmed from.

You guys can hide behind my blast shield too if you want. Plenty of room.

Nah, I will cherish it like the front row at Gallagher.

[EJSG19]

Solid reference Strad.

I'll stop thread-fu'ing before this point goes un-discussed.

While you are waiting for SS, here is a good read on part of the subject: The dangers of shooting .40 S&W in a 10mm pistol.

...here hold my beer............

[Seismic Sam]

If you are serious about shooting start reloading. You can reload 10mm for around the same price as 45ACP, maybe less. You probably can even just use 40 brass and load long.

You sir, have just posted an opinion that could get somebody killed, and we're not talking possibly here. In addition, this opinion has to qualify as both the most dangerous and most ignorant I have ever read on the internet. Do you know if the 40 and 10mm operate at the same pressures?? Uhh, gee, two nearly identical caliber cases, and one drives bullets 300 FPS fater than the other one. Well dumbazz, they do not operate at the same pressure, and if you had ever read a reloading manual that lists the SAAMI pressures you would know that. In addition, how do you think you can get an extra 300 FPS out of a cartridge withOUT running the pressure up?? Got an answer for that, Mr. Expert?? The SAAMI pressure for the 40 is 35,000 PSI, and the 10mm is 37,500 PSI. Yeah it doesn't look like a big difference, but another fact which I'm sure you are totally ignorant of is the number of KABOOMS that have ocurred with handloaded 40 ammo that have occurred in guns with barrels that do not completely support the case, and the most notable example is the Glock. You go over the limit for a 40 even a LITTLE bit, and the base of the case will blow open and that 40,000 PSI pressure will blow open the gun and probably phuque up you hand and possibly other parts like your face in an instant. So, a slightly overloaded 40 can blow a Glock to bits, and you are advocating running a 40 case loaded to 10mm pressures as acceptable?? Do you by any chance know a good lawyer, because you may need one after floating this totally ignorant opinion on the internet, and as you may or may not know, stuff you put up on the internet doesn't necessarily go away if you delete the mesasage. If your post gets copied to another board or a newbie reads it here and tries it, you are FULLY liable for what you have posted, and like I said, this little tidbit of yours could easily get somebody killed. As a matter of fact, I will bet anyone $100 that a 10mm factory spec load packed into a 40 case will blow with the FIRST shot in any gun that has a barrel that does not fully support the base of the case.

Quite frankly, I would hope one of the mods on this board permanently bans your azz for posting this, because it's truly THAT dangerous and criminally negligent to say what you have said.

[Seismic Sam]

What do you think Sam: if you load 10mm up to spec in that gun, would you need one of those recoil dampening thingamabobs in that 1911 to keep from battering it to pieces?

And to answer the intelligent question, no you do not need a Sprinco recoil reducer in a 1911 provided you have the right spring strength, which is 23 lbs. for a 10mm 1911. If you are shooting only 200@1200 loads I would put one in for good measure with a gun this expensive, but 23 lbs. is what's recommended for the Colt Delta Elite. (The Delta's were sold with some funky double spring with plastic base plug, but the first thing you do if you get a used Delta is throw that away and get a 23 lb. Wolff spring with a FULL LENGTH 1 piece recoil rod.

[DeanC]

Epic.

[bofe954]

Ban me if you want, I'll get over it. In general this site is the same two, three people arguing anyway.

10mm is no more expensive to reload than 45ACP.

You guys are right. Loading 40 to 1.18-1.22 is common, and you can load 10mm to the same pressure as 40 S+W if you want. I was confusing loading to a longer OAL with headspacing though, which isn't right. He shouldn't try and run 40, (even loaded long and to 40 pressure) in a 10.

He could get a 40 barrel, there are a lot of options. Many more than just whining to the guy about how expensive the ammo is for the new pistol he just bought.

Apparently you aren't getting the message, you ignorant little waste of oxygen and bandwidth. What YOU advocated was loading a 40 case to 10mm pressures, and made absolutely no qualifying statements like the ones above. The headspace issue is the least of the problems that your uneducated brain failed to grasp, although it could allow the entire head of the case to blow off rather than just blow out the lower side. You just laid it out on a public forum that you can load a 40 to 10mm pressures, which means that you weren't even thinking about pressure levels, much less headspace. So all you really knew about this whole issue was that the 40 case and the 10mm case are close to the same, and from there came to the conclusion that you could swap out the two. Wow, are you a handloading expert, or what??

Like I said, you're legally liable whether yoo want to beleive it or not for posting that opinion, and if some gullible newbie reads it (and we get about 1 a month in here) and blows himself up, you're looking at a personal injury lawyer oozing slime as he slithers up to your front door, and slapping you with a high 5 or low 6 figure lawsuit. Whether you you have the intellectual capacity or motivation to want to believe that is of no consequence to me, because it's your naive ass that is hanging out in the wind and waiting to get tapped. What you posted was far WORSE than advocating holding a gun with your finger on the trigger, or carrying a gun cocked with the safety off, or even pointing an empty gun at one of your friends as a joke. All of those, as bad as they may be, might only lead to an increased level of risk of getting somebody hurt or killed. The information you posted was so criminally ignorant that it would almost certainly lead to someone getting hurt or killed the first time they did it. You are a complete embarssment and huge liability to the shooting community, and are essentially doing the work of the anti's for them by offering the kind of advice you did. With people like you around running their mouth off, the argument that some American citizens are too stupid to own and operate firearms has some obvious validity.
