6Dasher primer testing

[BenPerfected]

Today, I am getting good results with 32.4gn of Varget, CCI 450 primers and Berger 105 Hybrids & .018 jump. As I proceed down the endless accuracy journey , I was thinking about just trying a quick primer change/swap in this same load to see if there could be more. Has anyone tried this with any success? What primer would be similar to the CCI 450?

I was coming up on the end of a lot of powder so I wanted to get a muzzle velocity test of my load so I know where to shoot for on the new lot. Below is the test I shot, my accuracy load was 36.0 grains of H4350 and the F205m primer.
Once I got what I needed I decided to load 5 with the 450m and see what difference there be across the MS. I decided to stay with the Federals for the velocity I don't feel the ES was enough to worry with.

James,
Your primer test with the H4350 looks like they provide similar FPS results. My thought is to shoot just a few rounds to see what happens to accuracy. Did you see any POI are accuracy change at the target?

I was only shooting out to 100 yards and no impact change all went into same hole
