Calling any Coggie owners here who may have a .450 3 1/4” Nitro. Need to know: is your gun the 440gr or the 480gr proofing? If 440gr, any chance of sharing your load data? I’ve been using a load the original owner gave me - 89gr AR2213SC, 1gr Dacron and 440gr bullet. Chrono’d at 2100fps. (*disclaimer, what works for me may not work for you.*) but I’ve heard troubling stories about Dacron so an somewhat concerned by its use. Also what’s the go with Trailboss? I’ve heard mixed opinions - some say it’s fine others say steer clear? I’ve tried it with 350gr cast bullets and it seems fine.. but I’d like more experienced advice. Cheers, Troy.
