I just shot mine today with 59.5 grains of RL15 and 66 grains of AA2000MR. No issues and JD338 as my witness. My rifle is a newer Ruger M77 Hawkeye with a Shilen SS barrel. It’s Shilen’s top shelf barrel with a match grade chamber and 1:14” twist. These loads are stout but the spend cases show zero visible signs of pressure. They look as good as spent factory loads. Recoil is much like a stout 06 or well behaved 300 mag. Both these are accurate loads not just stout loads. I only use Hornady and Nosler brass or reformed quality 06 brass. Remington brass has given me a real headache. Remington brass has hung up in the chamber with book start loads. This is from factory 200 corelokt ammunition and I’ve heard rumors of poor quality brass used in factory ammunition. It’s found a new home in the giggly weeds.
