Just for shits and grins I loaded up some 190s over IMR4064 in a Hornady case and boy was it a surprise! I normally use H4350 or RL22 but I had some 4064 sitting on the bench and thought what the hell! I started at 46.0 and that's what I used for sighting in. These loads are so much slower than my others the drop was way off from my zero. The first three rounds are on the lower left square and the other two is what I zeroed with. I shot the loads using the OCW method and I don't think any are too much outside the OCW but obviously the 46.3 charge was dead nuts on. It clocked 2585 FPS from a 22.5 inch Rock M24 1/10 and the numbers were extremely consistent, ES 10 SD 5. The sun came out and my chrony started acting funny so I could not get any accurate numbers except for three more from the different charges. The fastest ended up in the 47.0 with one reading at 2637 fps. The recoil was so soft I could shoot these all day long but it really turns the '06 into a .308 at these velocities.
The shots in #7 was from another rifle...
