Berger 6mm 105 Hybrids & Vita N-140

[Nelly]

Any one have any success using Vita N-140 and Berger 6mm 105 Hybrids ? I'll be shooting out of a BAT action & 28" Krieger Barrel. Just looking for some decent recipes, not shooting more than 200yds at this time. Thanks..

From what cartridge?

No success. But not because of the N-140.

It'll work, depending on your choice of cartridge: 6XC, 6-6.5x47, 6BR yes; 6-284, 243, 6mmREM maybe not such a good idea.

I used it for 6XC though there are other propellants that work better. N-140 can be a tad edgy at higher temps.

A friend of mine shoots a 6mmBR with N140 and Hybrids. His load is 28.8grs. It is very accurate, however, it is moving only about 2700f.p.s. (in that vicinity).. Your posting states you are only shooting to 200 yards, that should be plenty of ummpph for that distance. Accuracy should always be your main concern.

I went to bed thinking I should have added "Start at 29 grains & work up; seat 'em 0.030" off the lands, see what happens."

Shootdots, & spclark, That's the info I'm looking for. I'll start at 28grs & work up. Do any of you know a C.O.A.L without doing the Comparator Ogive measurement. I already have a 0.030 measurement for the lot of Berger 105's that I'm shooting now but it's with Varget ?

N-140 should work as well as Varget in the 6BR. Unless you just have a large inventory of 140 why would you choose it over other 6BR favorites? Around here 30.2 Target with 105 VLD is the best shooting load for many of our shooters. The Hybrid just doesn't shoot as well as the VLD unless you utilize a 7.5 twist. At least that is my finding.

I'll add they both seem to shoot equally well for me in 6XC but I use either a 1:7.8 (original Bartlein) or 1:7.5 (newer Brux).

I use n140, Norma brass and 105hybrids. Plenty of march wins with the combo. Norma has less capacity then lapua, I would start at 29gr.

I don't know the base-to-ogive length. I believe he is 15 thousandths off the lands..

Thanks everyone, I'll put some together this week and do some tests next Thurs.

I was a long time user of Norma 203B & RE-15 for my Dasher. During the “shortages” I picked up N140, although the others powders worked fine, the N140 surpassed them in accuracy out to 1K. Average velocity is 2945 FPS with WS2 coated bullets, .010 off.

I have noticed with N140, when temps get above 90*, the barrel gets hot quickly, and the groups opened up.

On my (eastern) side of the Atlantic, more people use N150 in the 6BR with 105-108s in benchrest standard outfits than N140. I do know people though who prefer the 'quicker' grade and say they get better results.
