you are very correct they do not know, and we should not let that cat completly out the bag till airgun tech surpasses firearms. we need full access to their calibers meaning we need our airgun manufacturers to design and make barrels that can easily shoot the reload bullets they make, secondly and along with it our barrel rifling needs to be less and the bore needs be correct, a .357 needs to be able to handle a .358 rifle slug not just the .357 pistol slugs or the.356 slugs most of us are forced to use.
i mean i cant use barrys bullets electroplated .357cal but the .356 woerks just makes alot of noise going through the barrel.
this is a whole topic change so i will leave it there,, but i made a thread, THE FUTURE OF AIRGUNS .. its my thread and it says it all basically our tech needs to get better than theirs starting with their bullets velocity increase next by rifling redesign, and then we go big , someone in the industry needs make the pcp air pumps nano sized and able to fit into the guns. yeah i know it seems like a dream but say look at compressors 10 years ago and now, my gx l3 runs on lithium batteries and is less than 20lbs and will fit in a backpack. my mom has a tiny compressor in her trunk for the tires , it can go to 300psi and weigs less than 5lbs, we can make it as small as we need so my challenger standard big bore .357 just spit out a 220gr hollowpoint at 853pfi for a energy of 355and a half fpe plus whateveer the hollowpoint does , wow. thats more than most of the .457air rifles out there.
