Have you tried any H4350? It seems like it would be a great powder for that case.

Yes Sir. H-4350 is a good candidate for this bullet along with Varget. Have worked with both up front and numbers looked good. My builder "ODCR" suggest VV-N540 so wanted to give it a shot. Seems like the E S & S D is better with VV-N540 and with better M V #s. Will not rule either of the other powders out but for now will stick with the VV-N540 with swapping over to the Berger 135 gr. LRHT. Base to Ogive on these are far more consistent (10 bullets @ .0005 variances ) than the Sierra 131 gr. M K I am abandoning due to poor quality. I have not ever seen the variances in any Sierra bullet as I have found with these.

WOW!!! What a difference a bullet can make. I was doing O K with the Sierras but I just did not feel it was giving my rifle it's best. Worked with the Berger 135 gr. LRHT bullet today with powder check and seat depth. Checked it at 100 yds. a few mins ago and I think my rifle is a happy camper. I may turn the tuner a tad but I'm not sure it needs a thing.

Bill, that looks great.

Does the recoil impulse seem any more than a 6mm going about the same speed?

Not really. Very managable.
