Mr. Rawles:
The recent PTR-91 post by F.B. mentioned damage to a windscreen by ejected brass. I sometimes shot both rifles and pistols from moving vehicles during training exercises. The purpose of this vehicle based shooting was primarily to teach the futility of such. What a wonderful way to ventilate an innocent tax payer. Sometimes my passenger would shoot while we were on an Emergency Vehicle Operator Course (EVOC). Driving was even more challenging when dodging hot brass. (Yes, the passenger was shooting through either side window – rifle only, not pistol for these were judged too hard to control in a moving vehicle when shooting past the driver). Most of the vehicles soon developed shot out windscreens and ventilated doorposts.
Shooting from a stationary vehicle is a horrible option tactically because the shooter is constrained within the vehicle. Although the inside of a vehicle may offer concealment, only an armored vehicle should be considered cover. Long range tactical shooting can be frustrated by rocking of the vehicle by wind (especially in Chicago and the Texas Panhandle) or even by unanticipated passenger motion.
The sound of unsuppressed rifle and pistol fire inside a closed vehicle can only be described as tremendous, even with both ear cup style hearing protection and dynamic ear canal protection. This is a good enough reason to avoid such situations. Notwithstanding, bolt action and bottom ejecting short barrel rifles (such as the FN P90) offer tremendous advantages when shooting inside a vehicle over almost any other long barreled side ejecting autoloader.
The same post mentioned reloading dented cases produced by the PTR-91. It was mentioned that such cases could undented by reloading and shooting in a different style rifle (undoubtedly true). Old age has made me exceedingly slow and cautious about some things. Dents reduce case capacity which may greatly increase chamber pressure in unanticipated ways. Hence my recommendation not to reload damaged brass. This is a pre-Schumer risk I don’t choose to underwrite.
Whenever shooting and/or spotting for a shooter I wear military goggle style eye protection and dynamic ear protection.
Just some thoughts, – Panhandle Rancher
