I'd like to humbly inquire who here has a "modern" centerfire rifle with a barrel length of over 32 inches or more. Please tell what caliber/cartridge and bullet weight you are using. Any more details would be welcome too, i.e., like chrono results. I'd just like to get a better feel for the ultra long barrel stuff from folks who do it. My suspicion is that certain cartridges would really benefit. At this point I'm only interested in the ballistics aspect, but if you also carry your long-barreled monster over the countryside, tell me how fun that is.
