Finely got the time to get back out and re-test a couple loads. Weather hasn't been that great either but got a break and tried to make the most of it.
Re-barreld an old puma rifle and tested it for functon on the 1st outing. The 2nd outing I took some lee-160tl bullets out that were cast at the same time. Some were pc'd and others were lubed in a lyman 450/lbt blue the a coat of 45/45/10 added. The pc'd bullets held their own and the traditionally lubed bullets fell apart in the 36gr/2500+fps range. The groups looked more like a pattern. And the velocities were lower (around 50fps) then the pc'd bullets with the same powder/load.

Put a 2nd coat of 45/45/10 on some bullets from the same lot/batch and went out and retested. This time the lubed bullets got the same velocity as their pc'd counterparts.

While either group is nothing to write home about, the 2600fps load did manage to do a 2" 10-shot group.

I actually could care less about groups/accuracy at this point. The 1st/2nd & now 3rd outing's are giving me excellent feedback. Need to bed another 1" of bbl, put high rise rings on and use a real rear bag to get rid of the horizontal stringing.
I shot 10 fouler shots in a clean bbl to season the bbl for those 2 10-shot groups pictured above. The clean bbl looked like this, shinny.

The whole length of the bbl had an excellent light wash/coating in it. That 45/45/10 is impressive.

I couldn't be happier to see the 45/45/10, traditional lubed bullets come around and equal their pc'd counterparts. I need to get the rifle dialed in so I can do head to head testing with the same bullets/powders. I like pc'ing bullets but I also like the traditional lubes also. When I finish burning up the lbt blue I probably switch over to the 2500. The 45/45/10 is going to get a workout and I did buy some of the jp floor wax but never did get around to making any.
The lee/pc'd combo looked real good with a 38gr/2700+fps load. Going to have to try the traditional lubed lee's with the same 38gr load.
