MagMarc- I also have a R77 Hawkeye SS 358Win & haven't found it to be any better than ~2MOA, at best. I haven't played w/ the bedding at all other than observing the fore-end is not free floated. I've tried a few 200gr Hornady PSP w/ H4895, Varget, RE15, & IMR3031 but no better than 2-3MOA.With RE15 I got up to 49gr, probably about 2400fps (chrono was having problems) and no signs of any high pressure (Win brass, Fed 210) or great accuracy. However, my actual hunting bullets have been limited to Barnes 180 & 200gr TTSX and have tried many powders (TAC, Xterminator, AR Comp,& Benchmark) but better than 2MOA has been elusive. I also have a Ruger American (20" barrel) 358Win which has done much better w/ the 180gr TTSX & H4198, about 3/4 MOA @ 2700fps, using 43.5-45gr.I saw this load in the first Barnes Manual for the original 180gr X bullet, not the TSX/TTSX. I would definitely use the RAR w/ this load for pig or deer w/ confidence. Good Luck! -Mark & Belle
