It does look good. Anything over 3100 with a 140 is bonus

Dr Mike -
Run the 140's through QL with the 6.5 WSM (Rock) using R33 and see what it says. I found a nice load with R25 last Sunday, but only bought 1 lb of it for load work. It might be interesting to try R33 to see what happens before I invest in an 5 lb jug of the two.

Thank you sir!
I have eyeballed RL33 a bit, and there is extra speed there as well. Just not sure I wanna rework another load with RL25 shooting so well in my rifle. I think I'll be able to step away from the bench if I invest in a 5lb jug of RL25.. My cheap side will kick in and keep me away.
Plus, as long as nothing changes, RL25 and my 264WM are really awesome. Tickling 3200 with both the 140 BT and AB, AND, they shoot to exact same POI. It is a great combo. It is actually a ton of fun putting rounds on target out to 600, just paste the circle and press the trigger. Makes it really nice.

Very Nice I was wondering what about Noslers 120 BT & 130 AB? I am useing IMR 4350 with 120 BT Max load what would I gain ? Model 70 XTR with a 24 inch barrel is my Rifle. Is Reloader 33 temp sensitive ?

The only thing I've found it likes is 60gr of H4831 with a 140gr AccuBond or Berger. I tried for a long time to find a load and finally settled on this one. The seating depth is wrong according to Berger, but I found the AccuBond load and left the die set the same. The AccuBond load is running 3000fps and the Berger 2950fps.
