I have used Berger 130 AR's and 130 VLD H with great results. Have also used 140 &142 Sierra Match Kings on paper. All 4 bullets shoot 3/8 or better if I do my job. Use H4350 cci 450's & Lapua brass. I prefer the 130's for the extra speed even though I dial the scope.

try flat based bullets, I get better groups with flat based like Partitions or H165 sp than with boat tails

I have and use the Hornady AOL gauge as part of my reloading. Have yet to find a bullet that touched the lands and will still fit in my Mark V mag and/or will have .308 of the bullet in the neck. I get useful information from all my none Wby cartridges, for the 300 there is no way touch the...

Hi, I also have a 300WBY (made in Japan) when I do load development I either start a 3.700 max length that fits in magazine or whatever loading manual suggests. Once I find a promising load I retest the load at different AOL's using .030 differences between 3.560 and 3.700 to see if anything is...

I think I will try some IMR7828 if I can find some. I also shoot single feed 3 or 4 shot groups with complete cool down between groups. Was out his morning with much the same results, nothing I would write home about.

Hi WildBill, I just got a 300 WBY re-barreledwith brake and I am having the exact same problems you are having. 2 touching or almost touching and a flyer. I have tried 165 Nos bonded, 212 eldx's 178eldx's and 180 Nos pp partitions. I got the 180 partitions to shoot ok but only at a aol of 3.600...
