Hello Airgun Nation. I’m new to the modern air gun technology. In fact the only air gun I currently own is a 50 year old Sheridan Blue Streak (5mm). All time favorite. Still use it today. So much nostalgia when I take aim at a pesky yard rodent.
I joined this sight to keep learning and researching as I want to get into the pcp hobby. So much to learn so many decisions to make
My general questions is related to big bores. It appears most (all perhaps) manufacturers have gun down the road of using bigger calibers and heavy bullets to get increasing fpe (.357, .457, .50, .72 etc.). Having some knowledge of using .30 cal subsonic rifle ammunition (.308 and 300 black out), I would like to know why we don’t see .30 cal +200 gr. rifle slugs being thrown out at 800 to 900 fps from modern pcp rifles. It does not seem to be physics as similar energy is being achieved with the larger caliber pcp’s. The .30 cal subsonic round has proven itself in a conventional rifle ( with the right barrel twist) I would think that could be applied to a pcp. Obviously this idea is of interest to me because of my familiarity with reloading and shooting 30 cal subsonic. Appreciate the comments.
