AzShooter Posted September 4, 2015 Share Posted September 4, 2015 Well the day stated out pretty good as I went to test my loads with a number of different bullets. When I tried my 3.2 grains of V V 320 with a 147 grain bullet on the first shot I locked the cylinder up. After inspection I found that the cylinder had blown up. Now it goes back to Smith & Wesson for repairs. I was just getting to like this gun. Link to comment Share on other sites More sharing options...

alecmc Posted September 4, 2015 Share Posted September 4, 2015 For those of you worried about coming to California because of it's gun laws. Just look at the results of the major matches held here. There are more Open and LTD shooters than L10. Uhm....ok....? ... Thanks?...I think Link to comment Share on other sites More sharing options...
JohnRodriguez Posted September 5, 2015 Share Posted September 5, 2015 (edited) I think that it is a instant felony to be caught in Kalifornia with a high cap mag if you are not a state resident. it is one of the reasons I have a commander length single stack for traveling into Kali. Thanks for inviting us to break the law though sorry to here about this Steve. I went outside to check were a 6.4 gr of vv320 is and it is about 1/16" from the top of a 9mm case. with a 147 gr zero and 3.2 gr of vv320, you can seat the bullet .300" (1.105 OAL) before it starts to compress the powder.

MrBorland Posted September 5, 2015 Share Posted September 5, 2015 Glad you're ok, but something doesn't sound right. Sounds like a pretty standard load IF you really loaded 3.2 over a 147, the COAL was right, and the gun was in good shape to begin with. Link to comment Share on other sites More sharing options...
peterthefish Posted September 5, 2015 Share Posted September 5, 2015 I know a guy who blew up a 627 cylinder. Just the cylinder, not the top strap. He was running a TG load in Short Colt that would have been hot under a 115 9mm under a 158 GR Berrys. Calculated the pressure on that one at 60K+ PSI - I'm assuming you made similar pressure somehow. Link to comment Share on other sites More sharing options...
revoman Posted September 5, 2015 Share Posted September 5, 2015 3.2 N320,160 2 Alpha Bullets coated, seated 1.160. Now these are short colt loads and no pressure problem. I have a friend who runs 3.7 N320 and Berry 158's in short colt and no pressure problems. Sorry about your revolver. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted September 5, 2015 Share Posted September 5, 2015 I'm guessing that the last shot before the 1st shot of N320 was a squib, resulting in a bullet locked in the barrel??? Are you using sufficient light to see the powder in every cartridge case before you put the bullet in? Link to comment Share on other sites More sharing options...
AzShooter Posted September 5, 2015 Author Share Posted September 5, 2015 (edited) Here is the cylinder. Hopefully the picture comes out o.k. Didn't sound like a double charge. Next two bullets lodge in the cylinder with split brass. Smith wants me to send it back with the remainder of the loaded bullets.

onebadeye Posted September 5, 2015 Share Posted September 5, 2015 I load 3.3 with a 147 bayou at 1.135 for my g34 and never had issues. Link to comment Share on other sites More sharing options...
NoSteel Posted September 5, 2015 Share Posted September 5, 2015 The load as stated with that pic just doesn't make sense..... I run 3.4gr of N320 in my 929 with 147gr RN Blue bullet @1.14 with no issues at all.. Possible the cylinder was in it of time??? I'm confused.....

Toolguy Posted September 5, 2015 Share Posted September 5, 2015 Maybe that cylinder didn't get heat treated? Link to comment Share on other sites More sharing options...
thermobollocks Posted September 5, 2015 Share Posted September 5, 2015 Cripes, seems like a 9mm cylinder would eat it way before that if it were a heat treatment issue. Link to comment Share on other sites More sharing options...

If it's in time enough to hit the primer its in time enough for the bullet to align the cylinder as it jumps to the FC. Squib or Double charge.

JohnRodriguez Posted September 5, 2015 Share Posted September 5, 2015 (edited) A 6.4 gr fills the case and squib will typically vent out the cylinder gap, I know, done it 3 times with my 45 over the years Edited September 5, 2015 by JohnRodriguez Link to comment Share on other sites More sharing options...
1911Prof Posted September 5, 2015 Share Posted September 5, 2015 How would a squib blow out a cylinder unless the previous bullet was still lodged in the barrel and if that were the case wouldn't that be pretty obvious? I'm new to revolver and this doesn't make sense to me. Link to comment Share on other sites More sharing options...

pskys2 Posted September 5, 2015 Share Posted September 5, 2015 Why do you think S&W want to see the loaded rounds? They expect to see something like a double charge. Don't get discouraged, many have been down this road. Just glad you're ok. Link to comment Share on other sites More sharing options...
