300BlkTalk

Hahaha - yeah, the front range weather has been a bit erratic. My commute to Denver from Fort Collins has been somewhat exciting occassionally. Look forward to seeing your data when you get it.

Thanks!

Interesting data. Nice resource. Seems to mirror my (limited) data RE VV N110. Any data with 300MP on the Sierra 125 SMKs? or Amax 208s?
Also was any of this run with a supressor?

Thanks!

It also looks like you are using mixed 223/556/300blk brass. These may have differing case capacity and hardness resulting in your somewhat mixed signs of overpressure that are very clear in some cases and less so on others. Try and sort your brass for more consistent results.

From memory regarding the speed... Sierra 125gr OTM with 17.0 grs of VV N110 gave about 2020 fps with a 16" barrel. 17.0 gr was a case full, partially up the neck. Had to shake each round to settle the powder. Seemed accurate and clean. Have more loaded to test - I mounted a better scope on the...

Just started working with them. Seem to be very accurate. Base of the bullet is right at the shoulder/neck when loaded to mag length. Seem to feed flawlessly with standard GI mag.

I always thought the "conventional wisdom" was to use standard primers with extruded powders and magnum primers with ball powders. Goole that subject and you will get a lot of affirmative responses. Something to do with ball powders being slightly more difficult to ignite, and getting bett...

So, any followup on the N110 loads? I can just barely stuff 17.0 grains under the 125 Sierra...loaded to 2.250" OAL.
