Chap thanks for sharing. I was looking at .458 barnes myself and with a good supply of CR sabots/h4198 I may just have to give them a go. As you have seen 4198 has potential with the 300gr buts requires you to search for the right pressure to find it's sweet spot. You maybe able to shrink those groups my bumping up a tad, my rifle liked 68-69gr under 300grs. The recoil will be up though, when developing I actually didn't notice the push but once I started fine tuning and shooting it a lot my sweet spot of 68-69grs started to beocme more noticable

. That was with the terrible tupperware stock though, the laminate is easier on the shoulder from a to z IME. We'll see how the newstock translates recoil...if i ever get it!!![:@]
I totally agree with your feelings about chasing accuracy, had my fillplus my time right now is short in supply.I amsuffering from Savage burn out actually. Misfire's I have had were with powders 4227 and RL7 (dirtypowder and didn't realize howmuch carbon build up was in the vent). Primer CCI mag 209s had half a dozen that neverstarted the fire, all I needed to toss them in the dumpster.So far nomisfire's from bullet/sabot or compression of load.
