What kind of velocities can you get with the Dasher/75 Vmax combo. The rifle is a LRPV with a 26" 12 twist barrel. I am looking for a good 3-600yd PDog load. Hoping for 3500fps or so.

I have a 23" long 8-twist 6mm Dasher that I have been shooting the 75-grain V-Max bullets with IMR 8208XBR powder. My sweet spot as I call it, very tight groups with single digit stand deviations is 3300fps, I have ran it up to 3400fps without any signs of pressure however, my groups and SD started to increase.
So with that being said, 3500fps plus with a 26" barrel shouldn't be a problem.

I'm getting 3345 FPS with the 70 GR. Nosler BT using IMR 8208 XBR with single digit SD in a 22" barrel. That combination in a 10" twist is very accurate in my standard 6mm BR. I would thing the Dasher should do much better.
Just to give you another indication of what to expect.

How much power have you used?

H335 with the 75g V max will get you some very good velocity with accuracy in the extreme, with Rem 7 1/2.
I will have to look at my data, but it was in the realm of 3550 at the node(70g Sierra blitz king's node is 3650), mine is a 12T with .030 freebore, 26" or so.
H335 is easy on barrels, H4895 and 8208 are NOT easy on barrels, I can not stress this enough.
Another option is the .020-.030 freebore 6x47 Lapua where the 70g bullets are right at home at 3700 in a 26" barrel.
