Started at mag length and 20 g of varget,hey that was good.20.5 was a knothole.2 guys with braked 300's showed up next to me so I packed it up and went home,went back to the range later in the week,shot 5 at 100,10 at 200 under an inch.Never even bothered with anymore developement and used the rest of the loads for foulers.That was easy!
