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.
Right, I intend to try 67g, 68g and 69g next weekend. I think I will stop there, I have heard of people shooting 73! That must be a heck of a recoil with that powder. Actually if I don't get better at 67g, 68 or 69, then I will shoot the 66g, since that is acceptable accuracy for me, it looks like right at 2", maybe a bit less, but 2" is fine with me, for hunting. I do like shooting the milder powder, it is really all I need for most of my places to hunt back east here. I am only playing with the Barnes Origonals for my Colorado hunt for elk, and I will use the 300g Barnes Origonals with a CR sabot. Not sure if I will use the 4198 or the 5744, I need to shoot the 4198 a lot before I am totally comfortable withit. Actually today was the first day I can say I shot that powder and it performed like it was suppose to with a sabot from my gun. Before today I was getting misfires with it, but I do know the reason now.
I need to drill out my breech plug, since I shot 20 times today. I find about 25-30 times is all I dare to go with it, once the hole gets really really small, I don't get reliable ignition. All in all I like he .458 bullets mated with the CR .452 sabot, sees to work good in a Savage. I predict that it will also work great in Blackhorn, since this is close to a smokeless powder in both design and fouling that it leaves in the bore. Chap
