I am getting ready to load up some 200gr LSWC with N320 Vihtavouri powder. I was thinking of 5.0gr per load. Any one else use this powder?

I use a standard load of 5.5g VVN320 under a 230g. Montana Gold hardball round. I shoot that load in ALL of my .45's. It's mid-level in power and gives me enough recoil to keep keen on follow-up placement. It's accurate and chronos around 850fps from a 5" gun.

I prefer to keep my reloads at a realistic power level. I'm sure it's fun to pop caps into paper with nary a bit of recoil, but I take another approach. I try to construct my practice loads to approximate carry ammo to a point. I believe that shot to shot control is very important and I don't want to get complacent with lighter loads. I use a combination of humanoid and steel targets.

This is MY procedure and I certainly wouldn't expect it to work for everyone.

I have used VV320 with very good results. Most of my off duty shooting is done at a local indoor range and I load for accuracy and mild recoil. Here's the load that has met both of those factors for me:

4.6gr
230 FMJ Montana Gold
Starline Brass
Winchester Primer
OAL 1.240

This load cycles all of my 1911's with 16lb. recoil springs and is very accurate.

I've been using 5.0-5.3 grains under Berry's 200 grain plated slugs.

N320 coats my feedramp with alomst a varnish that is very hard to get off. Never seen anything like it.

N320 is my favorite poweder. For 200 grain lead, I use 5.4-5.5 grains. I find it is exceptionally accurate and this is my IDPA load. (It makes their 165 power factor but is not very far beyond it.)

I use 200 grain round nose flat point lead cowboy bullets, so you should get similar velocites with SWCs.

This is from Wilson Combat:

4.5gr Vihtavuori N310
200gr H&G #68 L-SWC
Winchester LP Primer
1.250 OAL
.469 Tapercrimp
850fps

Good Luck

My usual IPSC/IDPA load is a 230TC over 5.1 N320 (190pf). For yucks, I put some Speer 200 SWCs over the same charge, and the gun was short-stroking. I needed to go to 5.3 to get the gun to cycle reliably. N320 is now the only powder I use in my .45's.

I finally got the 10mm together. Does anybody have any loads for the 10 with N320? I have found some with N330 and N340.

Right now, I am only using N310 in .45.

230gr West Coast RN
4.3gr VV N310
OAL = 1.245
WLP
PF = 175 to 180

5.3 gr. of N320 with 200gr. West Coast Total Jacketed bullets in 5" Wilson barrels result in 775-800 fps.

5.3 gr. of N320 with 200gr. lead SWC bullets in 5" Wilson barrels result in 850-900 fps.

I shot N320 for a while; 5.2 grains with a 200 gr SWC, either cast or plated, did ok. A friend tried it with 185 grain JHPs (5.9 grains, as I recall) and got occasional off rounds. Some just sounded strange - he would stop and look as though it might have been a squib, but it never was - some gave short recoil malfs. This was prevalent enough that he shot ball at the IDPA Nats because he did not have time to redevelop loads with another powder. I would not use it with bullets lighter than 200 gr. Actually, I don't use it at all any more, back to 700X for a common powder in 12 ga and almost all non-magnum pistol ammo.
