It is also one of mine. My most accurate rifle is a 20 year old Browning .30-06 A-Bolt with a BOSS and Leupold scope. I can bench rest groups under 1 inch at 300 yards. (Don't ask me to do that standing, LOL) Every deer that I have shot with it has immediately dropped, literally they didn't even take a step.
One of these days I want to get hold of a Remington 700 long action .300 Win Mag and build a M24 clone ... Just in case I want to reach out and touch someone.
I have from time to time thought about building a big bore rifle with long range accuracy. My first thought was a Ruger No. 1, but have heard a lot of horror stories about barrels.
I already have a model 71 348 Winchester. That is a thumper. Kicks like a mule, but 250 grains at 2300 fps really has the knockdown. I recently found some new brass for it and some Hornady 200 gr. FTX Leverevolution bullets for it. Have not loaded them yet but am looking forward to shooting that.
