Viht N135

Attachments

in the 30 BR N135 is too slow to achieve velocity that H4198 will produce. It is more a powder adapted for the 30x47 length rounds. In a 6mm BR it does work and folks use it. Not sure about Dasher/Grinch as I have no experience with them.
 
Just touched off 9 rounds fireforming 6 br to dasher using 105 gr bullets and 30 gr of 135. No pressure and .25 group for three shots. No crno data, the mice ate the wiring. Just bought a labradar.
 
I've never used it personally but say loading data that came with a 308 FT-R rifle my friend bought. There was considerable data using N135 with both 185 Juggs and 200-20x bullets. I would never had believed it had I not known the winning history of the rifle.

Vv135 in 2 straight 6brs was the ticket for me with 80 and 88 gr Bergers. Shot small at 100 and small at 500. I sold the one to a fellow who used the same load and broke his clubs 600 yd record the first match he shot.
 
It's very close to N140. It was developed specifically for 7.62 Nato 143-150gn FMJBT loadings to give optimum case-fill, consistent port pressures. and standard PMax values / velocities.

In the UK, N140 and N150 are regarded as superior in 308 with heavier bullets, both too in straight 6BR with 105-108s. The late Glenn Zediker and others reported wide use with the 80gn SMK in the early days of 223 AR-15 Hi-Power SR use, but it was ditched for N140 after that became available as N135 was a fraction too fast burning and therefore prone to produce over-pressures in some lots and/or conditions.

I'd have thought that would apply to the Dasher, but who knows until you try it?

Have you got a Berger book if so I think it has a listing for 90gr in it maybe not with n135 though it should do good start out low and work up
