I shot at the OKC gun club rifle bay once that has the concrete benches. The top skin is sheet metal and they sprayed insulation underneath. Above each bench there is no insulation in a circle. I was told that was because of brakes jetting the gas upwards and blowing it out. Some jet the gas sideways and some up evidently although I've never seen one that jets the gas up other than small ports to mitigate muzzle rise. Brakes are very effective in what they are designed for, but detrimental to maintaining normal hearing.
I picked up my first 300WM a few months ago and will be deer hunting with it this season some. The recoil is definitely there but gotta have plenty of knockdown for these mammoth SE OK whitetail. Lol I’ve never shot a 6.5 Creedmore but I’m diggin’ the 300.
Man, those are 2 totally different rounds. If you are deer hunting in Oklahoma the 6.5 should work just about anywhere. There are places out West if your willing to shoot a long distance you may prefer the larger 300.
I bought the Ruger all weather SS 77 in 300 win about 15 years ago. It’s been west several times for Elk and Mule deer, but I have shot many a whitetail with it. That gun loves the 180 Barnes all copper bullets and does fine with the 150’s for Whitetail. It’s my go to rifle now days and the recoil in the 77 is not any worse then the old 30/06. Only time I really notice it is a long day sighing in the new scope. My 300 win will most likely be handed down to my son, it’s a keeper. my son prefers the 6.5 CM we built and both rifles will be going to Montana again this year.
I watched a clip a few weeks ago by some gun writer that compared the .270 Win. and 6.5 Creedmoor. According to him both were pretty equal out to about 600 yds. after that the .270 had less drop. Usually less drop way out means more knock down power but, not always.
I don’t think I would ever shoot over 400 with a dead steady rest at a deer but it would be fun at paper or steel
