Ran mine up to max 460 S&W loads (40 grains of H110)with a powder coated, gas checked 300 grain bullet. No signs of casing pressures all the way to the top. My tightest group was with 35.5 grains of H110 with an average Muzzel velocity of 2070 fps. I shot a 1.5" group with 38 grains as well. Anything above 38 grains and the accuracy degraded. I can tell you once you get above 36.5 grains, even with the brake, the gun starts smacking you pretty hard. Kicks more than my 300 RUM above the 38 grain plus level. Check some my old posts on this forum with group sizes I posted. Ruger uses the same action on their 60,000 psi 300 WSM. The problem is the rest of the gun can't handle the recoil. I had two optics slide, one was wrecked, the scope rail keeps comming loose every dozen shots, the actions screws back out, the trigger housing holes hogged out from vibrations, and now the bolt release catch pin falls out because it's too loose. I acraglass bedded my picantinny rail last week and lock tited the base screws along with spraying 3M adhesive inside the scope rings. I also over torqued my warne rings to 35 in pounds this time since 25 in pounds doesn't work. I also tried leupold PRW rings with rosin...scope slid in 6 shots. Had one magazine brake and another drop out ever 3 to 4 shots. I just got mine back from Ruger the second time and was told by Ruger the gun wasn't made for target shooting...its a hunting rifle. What's that tell you? It can't hold up to repeated use and they probably figure the aver joe hunter is going to put 4 boxes of ammo through in their lifetime. Ruger basically told me a cheap,disposable, throw away gun in so many words. I'd tell you try a savage first. About ready to sell mine and buy a Remington short action rifle and have it rebarreled so I will be confident I will have an action that can handle the round and won't fall apart. The ruger is probably a great gun if you shoot nothing but sub sonics through it. I started a post called 450BM rattling apart a few days ago...might help.
