I purchased a 300 win mag Predator, and when I went to pick it up at the LGS, I asked about a Standard American in 450 Bushmaster they’ve had for some months. They knocked off quite a bit on the price….. and I went home with both. I’m dinging around getting them set up to go to the range, the 450 Standard has a better trigger, and smoother action, figures…. I put a McCarbo trigger spring in the 300 Predator, and that made a huge positive difference, I’ve got one for the 450 also. I’ve been working the action of the 300 Predator while watching tv, it’s lubed up kind of heavy, and I just work the action and pull the trigger, as it’s lifting the bolt that’s the rough spot. I’m not new to bolt action rifles, but it’s been decades upon decades since I’ve been shooting frogs and Muskrats down by the creek as a youngster. I’m not a hunter, I just don’t like killing things anymore, just me, so these are range toys. I’m new to reloading, and this whole new world of shooting opening up for me. Thanks for listening.
