Heavy bullet loads for .243 Ackley

[BEEMAN]

Rifleman. How's the on game performance with the 103 ELD-X? Built a 6 Dasher hunting gun. Was going to shoot the 105 Berger but it won't shoot those accurately.

Anyone have a good accurate load for the .243 Ackley with 87gn V Max , 90gn Berger BT or 95gn Berger VLD ? Want 0.5 MOA or better for 5 shots and not having any luck so far .
Best I have is 0.6 MOA at 200 yds with 87 V Max and 48.5 WXR .
Prefer H4831SC or RL 22 / WXR powders as have them on hand .
My rifle has 9 inch twist and not sure that it will handle the heavier VLD's . Interested if anyone has tried .
How critical is seating VLD's into the lands for accuracy ? Would like to use my Rem. 700 magazine if possible .

I was running Lapua brass with the HRNDY ELD-M 108 grain pills over 47.0 grains of H4831SC during the winter months, sub .5 MOA @ 100 yards and 44.5 grains during the summer months with the same results. 47.0 was to hot of a load for the hotter months, which resulted in over pressure at the primer pockets

I've recently switched the the Peterson SRP .243 brass and started load development last weekend. Best group was sub .5 MOA with 43.6 grains of H4831SC. Now I just need to tweak with bullet seating depth and neck tension to try and lower my ES & SD.

I shoot the older 105 Amax in mine, my friend shoots the 103s. I know he used it last year on antelope and did just fine. He's used it on quite a few coyotes and seems to be fairly explosive like the Amax I shoot. I don't know that he's used it on much larger than antelope though.
