TheOtherErik Posted October 28, 2002 Share Posted October 28, 2002 Any one have some starting load suggestions for N320 in .40? My box stock STI CA Edge feeds well with a OAL of 1.130. I think it would be self induced voodoo if I changed the OAL. I think most people using N320 are running about 1.20 OAL with about 5.x grains. Where do you think I should start with a 1.30 OAL and is it going to be safe? Erik- Link to comment Share on other sites More sharing options...
TheOtherErik Posted October 29, 2002 Author Share Posted October 29, 2002 oops....BTW I'll be using 180 gr montana gold cmj Link to comment Share on other sites More sharing options...
Flexmoney Posted October 29, 2002 Share Posted October 29, 2002 I found this by a poster on Glock Talk... ...VV N320 (4.7g, MG 180g, 1.125 OAL)...for major... That should be in the ball-park...work up to it safely. Link to comment Share on other sites More sharing options...
ErikW Posted October 29, 2002 Share Posted October 29, 2002 If you've got a gun that can run long-loaded, you might as well load to 1.20". Especially if you are going to use a fast powder like N320 or Clays. You might also find it shoots softer. Link to comment Share on other sites More sharing options...
TheOtherErik Posted October 29, 2002 Author Share Posted October 29, 2002 <If you've got a gun that can run long-loaded, you might as well load to 1.20". > Yeah, but my gun runs so well with my current OAL, I'd amost hate to change it. I guess it won't hurt to try. Link to comment Share on other sites More sharing options...
A33435 Posted October 29, 2002 Share Posted October 29, 2002 I've tried N320, 4.8 N320, Federal SP200 primer, 177 grains Frontier bullet, aol 28.65 mm. Shoot from my G35 with standard barrel PF 188 DVC Adrie Link to comment Share on other sites More sharing options...
Flexmoney Posted October 30, 2002 Share Posted October 30, 2002 I am with Erik Warren...you are better off (safer) loading long if your gun will allow it (and your gun should). Link to comment Share on other sites More sharing options...
TheOtherErik Posted October 30, 2002 Author Share Posted October 30, 2002 Ok so how long is too long and how do I tell if it is too long. Most people talk to are any running any where form 1.150 to 1.200. So what...just pick a OAL at random and go from there? Or do I start on the short end and work my way up? I know this may sound like a dumb question but ive allway been a bit leary deveating form published specs. Link to comment Share on other sites More sharing options...
EricW Posted October 30, 2002 Share Posted October 30, 2002 Pick 1.20 and you'll be right where you need to be. Link to comment Share on other sites More sharing options...
ErikW Posted October 30, 2002 Share Posted October 30, 2002 Some people go waaaay out to 1.24". Stick to 1.20." You want to stick to published specs and you are using N320?! Dude, there ain't no published VV loads with the heavier bullets and their faster powders. N340 is as slow as they go. The published specs go out the window at this length. You use considerably more powder. Flex's short load isn't even close. Link to comment Share on other sites More sharing options...
TheOtherErik Posted October 30, 2002 Author Share Posted October 30, 2002 OK you guys have convinced me... So I looked on jeff mass' loading page and a few entrys with n320 with a 180g bullet at about 1.20OAL call for about 5.0-5.3g of powder... does that sound about right to you guys. Or is your experience a little diffrent. Link to comment Share on other sites More sharing options...
DBChaffin Posted October 30, 2002 Share Posted October 30, 2002 That sounds about right to me. Just FWIW, I am loading a Zero 180 gr. JHP at 1.185-1.190 with somewhere right around 5.0 grains for 171-173 PF in my SVI. Good luck to you. Link to comment Share on other sites More sharing options...
ErikW Posted October 30, 2002 Share Posted October 30, 2002 Actually, I need a little more to get past 170 PF, but my guns are slow. David Benzick made 166 PF or something at Area 1 with about that much. Too close for me. Link to comment Share on other sites More sharing options...
Singlestack Posted October 31, 2002 Share Posted October 31, 2002 My SVI need a little more also. It was inconsistant at 5.3. When I got it up to a 172pf, I only had a single digit deveation. I load at 1.20 oal. Link to comment Share on other sites More sharing options...
John Heiter Posted February 22, 2003 Share Posted February 22, 2003 I tried going 1.2 in my .40 but ran into feed problems with the Precision 185 gr. truncated cones I was shooting. Dropped back to 1.155 and have no problems. 4.4 of n320 gets me a 172pf in a 5" Briley. Link to comment Share on other sites More sharing options...
ORCA Posted February 23, 2003 Share Posted February 23, 2003 Using a 180 Montana Gold with a OAL of 1.2 I use 5.3 grains of VV320 to get a power factor of 172. With a 155 I use 6.2 grains of VV320 at a OAL of 1.20 to achieve a power factor of 171. The guys are right a OAL of 1.2 really does feed a lot better than a standard length round.

warpspeed Posted February 24, 2003 Share Posted February 24, 2003 TOE, I have a STI CA Edge too and I know what you mean when you say it likes the OAL on the short side. I can feed empty cases for crying out loud! I do not shoot IPSC all that often but I really like a 180 gr Zero JHP over 5.0 gr N320 with a 1.150 OAL. I started out with 4.9 and it was too close for comfort to the 165 threshold. bumped it up 0.1 for a little buffer. 11 lb spring w/ one shock buff and it cycles and tracks nicely, for me.

Skywalker Posted February 24, 2003 Share Posted February 24, 2003 Erik, this link is to my own reloading data. If you wish to browse through more data, have a look at my club's website (english section for foreigners): www.teamoffire.it. I shoot an SVI Competition in Standard division and have experimented quite a lot with VV N-320 as you will see. My O.A.L. for 180 grs lead or copper plated bullet is 1.170", but I found out this particular load is not very lenght-sensitive in my gun. Hope you will find something that fits your request.
