VV 3N37 vs. N350 In 9mm - Advantages and Disadvantages

slickpuppy · October 30, 2001, 07:48 PM

I was working up some loads with 3n37 and 124 grain flat points and in the VV manual noticed that the charge weight was the same as N350. It appeared velocities were darned close as well.

Many of you are proponents of 3N37 and I was wondering why you would choose that over N350 in a 9mm?

What are the advantages and disadvantages between the two powders in 9mm?

Thanks

3N37 seems ideally suited to the .355"-bore size; N350 seems to offer more versatility as to bore diameter.

As for IPSC loads I use both powders in my 9X23, the N350 produces more gas at the end of the barrel making the comp work more better. As for working up loads useing the same charge weight for both powders the N350 will give me about 25 to 30 FPS more then the 3N37 will per given charge weight. The 3N37 powder leaves a little cornmeal residue in my barrel. I would use 3N37 in shorter barrels and N350 in longer barrels.

WESHOOT2:

You still have WAP? I'm almost out. Winchester did the same dirty deed to my Dad years ago when they discontinued 295. (It came back as 296...)

Regret the discontinuance less after confirming my experimetal results that WAP ain't so great in .357 Mag. Great in small semiauto cases.

Now if we coul only get Power Pistol in a low-flash version!

I will never run out of WAP (I use it for furniture).

I regret it terribly; without question the finest medium-to-heavy semi-auto .355"-bore powder (9x19, 9x21, 9x23, 38 Super, etc.) as far as the critical balance betwwen FUNCTION, flash, accuracy and velocity.
Add its cool-burn characteristics and you've got it all!

Ditto Power Pistol, but PP has a slighter 'slower' feel about it, and seems more versatile. It shines in different bores sizes, but the flash excludes it from most defense duties. The bigger the bore (and also certain specific loadings) the less flash.......great in 9x19, 38 Super, 40, and 10mm.

I have it on good rumor that Ramshot's Silhouette is ballistically WAP.
We'll see.

3n37 is the most accurate powder i have found for my taurus 99.i use 5.7 under a 124gr fmj round nose.i dont know the speed.i believe you will like it.
