vhitavouri N310 for 38 SPCL 148 HBWC

Post by Wobbley on 8/10/2015, 6:28 pm

Anybody use this powder for bullseye 38 HBWC loads?  Gun is a S&W 52.

think you'll find WST to be the best stuff around for the 38 and HBWC

2.9 gr

I have that too.  Thanks for the info.  But I am looking for some loads to try and N310 is on the list to test.

Back in the late 80s and 90s the RPD pistol team tested every 38 compatible powder known to man in an effort to gain an edge on the tough PPC competition during those years..
WST was the easy winner.. Not only accurate, but consistently accurate.. No unexplained flyers. Certain lot#s of 231 was also exceptional. 231 leaves an undesirable residue of unburnt granules, and not all lot #s shot the same..
Presently, my lady shooter is using Bullseye at shortline only..for her 52

WST for a HBSWC seated flush,  I would go with 2.7. -higher you might get some pressure signs.

just googling around a bit,  not a lot of info on 310 and the 38.. seems it's almost to fast burning to be safe and consistent.

even loaddata had nothing on N310

A couple years ago I tried N310 for my M52 with Zero 148 gr HBWC's and could not get an accurate load as compared to Bullseye.  N310 is a fast burning powder and apparently pressures build up quickly.  Some of my loads resulted in bullet separation, that is, the hollow base skirt separated from the front of the bullet.  Lower power loads of N310 just could not hold better than 3" group at 50 yards.  I had similar results using Clays and now stick with the classic 2.8 gr Bullseye for the M52.  If someone would make a faster twist barrel for the M52 then maybe there would be a better load for the long line.

Lapua's website does not list N310 for .38 spl but does for .357 magnum.
I would use the WST if I had it.
I have over 8#'s of Bullseye so that is what I use at 2.8 gr for the 148gr HBWC in my M52-1.
4.6gr in the .45 shooting 185gr jacketed.
Do use VV N340 for the 9mm.

Thanks guys.  Vhitavouri in their 4th edition of their data pamphlet listed the following for 148 gr Hornady DEWC
2.0 gr 610 fps 13000 psi
2.3 gr 700 fps 15000 psi
2.5 gr 740 fps 18000 psi (+P) data.

So it looks like I'll leave the 310 for the 45.

Wobbley is right..The pressure is  very high in relation to the velocity..
We tried 310 about 20 years ago in the PPC guns for the Dept.. Groups were nothing to brag about.. That was then..not sure about 310 now...
Our best grouping powders were 231 and WST with WST being by far the best.. I have to chuckle about the "Classic" 2.7 Bullseye.. Never could get that to shoot good groups with the 148 HBWC... But as I said, that was then, not sure about now...

I am not good enough to tell the difference, so I stick with the classic loads of 2.8 gr of BE under a 148gr Remington HBWC out of the M52 and 4.6 gr of BE under a 185gr JHP for the Clark Sr. longslide .45  Laughing

Besides, the 8+ pounds of BE will most likely last me till my end  Smile.

I do have 4# of VV-N340 that I will have to test in the M52 that I use for 9mm.

So long as the bullet velocity is the same the gun should be fine.  The vast majority of the recoil impulse is from the bullet.  IIRC, the Unique equivalent load was around 3.5 gr.  It was dirtier than the Bullseye load when I tried it in a Python I once owned.

Hornady lists 3.5 as the top end. I loaded some at 3.2 to try tomorrow. Hope it shoots well. I have about 18# of unique and I dont care for it in my 45.
