anyone use n-133 in a 6BR

[landman]

I just had a gun re-barreled to 6mm BR Lapua. My gunsmith suggested that I use n-133, however I can't seem to find any load data for a 6mm BR Lapua, using v-133. I am shooting a 24" Hart barrel with a 1 in 12" twist. My bullet selection is a 65gr. V-max and a 75gr. V-max. Maybe the v-135 is best for this set up I'm not sure. Has anyone tested the v-133. Any help with this would be greatly appreciated.

May GOD'S Peace be with all of you.

Try 30.5g to 31.0g of N135 with a 52g FB bullet, N133 is too fast. You may be suprised how the little 52g bullets shoot.

landman: N133 is one of my best powders in the 6BRs. Shilen heavy contour,.940" muzzle), 24", using 30 grs with the Berger 68 Match seated to touch, 205, Lapua, .265" chamber neck, .263" loaded round neck, 1-14 twist. Won a 300 yd. G'Hog match with that load combo last weekend. 10 shot group measured 1.221", shot off a portable shooting bench. My fault that I overcompensated for a slight wind from the right, or the score would have been higher. First 4 shots were in 1 hole in the 9 ring, 1 click left, followed by 4 xs' and 2 10s', for the winning score of 96-4x. 10 ring 1" in diameter. In one of my other 6BRs', am using 85 gr. HPFB,, faster twist) and it likes 30 grs. of N135. So, I'm using N133 for the lighter weight, slow twist, and N135 for the mid-weight and faster twist. 6BR remains my #1 favorite, all others take a back seat.

Kodiak99317,
Thanks for the response. I heard it may be to fast but I wanted to see who else may have used it and what their conclusions where. Thanks for the load data using n-135.
God's Peace
