Hi Guys: First time posting a question to the forum. Recently bought a used M&P in .45 acp in excellent shape. I was rooting thru the ammo room ( Im a reloader) and found a box of Super Vels (like new) They are about 35 yrs old and in excellent shape. OK to send some thru the tube? Anybody know how the old Super Vels stack up against the newer SD stuff out there like Zombies? Thanks for your help, mutt
