115 gr. Winchester RN Data Needed

[roostershooter]

I picked up 5k 115 gr. Winchester RN bullets yesterday on the cheap.

I would like a good, accurate, tested load for this bullet using Power Pistol, N320, N330, or N340. I picked up 8 pounds of PP and 4 pounds of each of the VihtaVouri powders listed.

Any suggestions?

What Power Factor are you shooting for, Major or Minor?

Are these the flat base or hollow based 115 grainers?

If they are the hollow base I've had good results with them in .38 super steel challenge type loads, but they don't seem to like major out of the guns I've tried them in. Knew a couple of folks who really liked them in major, though...so, YMMV. I have some load data for super, but not with any of the powders you listed.

I'm going for Target PF

Seriously, I don't really care about the power factor. I assume that these are hollow based bullets (exposed lead base) that I will be using for paper punching and slapping steel. Practice is my main priority for this bullet.

With the powders you have, I'd stick with the PowerPistol or the N-320. The other VihtaVouri powders are too slow for this application, IMHO. And the price difference between the two would tip the scale in favor of PowerPistol.

6.2 of PowerPistol should be an accurate load that runs around 1200 fps in most standard-length pistols. If it won't cycle your slide (I don't know which pistol you're using), then you have about 1/2 grain of "fudge factor" before the max load.

As far as "hollow-base" vs. "flat-base": Almost all FMJ bullets have exposed lead in the base. With the most popular manufacturing process (swaging), there has to be some exposed lead, whether in the base or in the tip. The "hollow" or "flat" refers to the base's profile. If it's a hollow base, you'll see a large indentation there.
