I have an R597 HB bought last April. Very accurate. Ammo picky. Likes CCI Minimag, CCI Blazer, Win M22, Fed 525. Win 525/55 is a hit and miss. Hated Win Wildcat. No plans of trying out Rems. 30 round mag is hit and miss with LRHO. Loading 20-22 rds seems to be acceptable. Metal 10-rounder is OK but a little tight to load beyond 8-rds. Aftermarket parts are hard to come by except for the stock, VQ hammer and extractor. I installed an Archangel 556 kit, Bushnell 3-9 X 40 scope, bipod and it looked better. Cleaning is a breeze. Total teardown is not required when using Rem action cleaner. Spray, let dry and use dry lube generously. With plated ammo, barrel fouling is not an issue. I had around 500 rds in my rifle, one barrel cleaning with barely noticeable fouling. And the best thing, available almost cost-to-coast compared to a Ruger. I am not a Ruger basher. In fact I am thinking of getting a takedown version. Both are decent guns. Both needs work to run better.
Safe Shooting!
