Hello Dary.
Should have mentioned, this one is an R360. The bolt handle is the only lug on this one, but for such a limited cartridge I an sure that it is within its limitations. The load that I tried was a 198@ 1800 (or whatever the load of 4350 actually clocked) but I may move back to 1500 with 3031.
Either way, it is shooting about 12" high currently and instead of changing the sights actually give it the load that was intended for it.
