It's not. If properly loaded, and the loader (commercial or individual) pays proper attention to details such as neck diameter and neck tension, setback in the 40 is no more likely than with any other friction fit, taper crimp round.Exactly how is the .40 more prone to setback? News to me!
...was told by a friend back east to NOT use reloaded stuff in the glock.
I have been recently hitting up the more mainstream areas(big box stores) and have noticed that ammo is mostly gone. 223,9,45 are have become an endangered. If any ammo is available, it's 40. I shoot a lot of 40 and one store today had 100's of boxes of fmj.
I know 9 and 45 are popular but I didn't think it was that big of a gap.
Am I the only 40 shooter out there? Why is it seem to be the only ammo available in large quantities?
Glocks do not have a fully supported chamber. .40 has a bad habit of booming in them due to that fact.
+1 Very well said.Rubbish. Unsupported chambers bulge the brass a bit making reloading a bit more of a headache, but they're not kabooming due to it. Reality is that some people screw up reloads. ANY gun - support chamber or no - will blow up if you try to shoot a double-charged case or other goofed load through it.
You don't want to shoot cast-bullets through a factory Glock barrel (be it reload or factory ammo) unless you know what to expect and follow a strict cleaning regime, but other than that its fine. The vast majority of Glock shooters that I know (including myself) reload for their Glocks.
If 40sw is good enough for the FBI, it's good enough for me.
Are you basing that on some publication or knowledgeable source? I would like to know of such a source, mainly to settle other discussions. Based on range brass pickup activities, it appear that 9mm is 75%, .45 ACP 20% and then all other (40, 357sig, 5.7,10). Of course this is based on one range and not a good sampling from other areas.is .40 sold in higher volume than .45ACP yet ?
I'm seriously asking, I don't know....
It seems that .40 is darn near 9x19 in volume these days.
Feel free to flog me if i'm wrong....
