One of my rifles is a custom Swedish Mauser that I converted to .45cal. It's got a 18" .452 bore pipe on it with a .45ACP chamber. Using .460 Rowland brass cut to .888" I can make some seriously snot rockety loads. The bolt is factory bent and it's got a Timney trigger on it with a Williams rear peep sight. I had originally put the front sight from a Swede carbine on it but that decided to join the going downrange club one day and besides never fit right in the first place. My coach brought me some old take-off military front and rear sights and I found one that not only swage fit the barrel really well but is also tall enough to do the job. This rifle is a punkin' slinger of the highest order. BC on .452" 230gn bullets is not far above zero. Last weekend I had taken it with some assorted loads of wildly differing power levels and was hitting 200m chicken silhouettes pretty well. Well enough that I'm sure I can take it pig hunting and be able to swat something out to 200m but also that's light and handy and puts the stomp down. With my top end loads I'm getting just over 2000fps with 200gn pills. That's AR-15 power levels. Bullet selection is a pain but nosler custom comps at 185gn seem to hold up really well as do a few of Bear Creek's hard cast moly coated lead pills. Yep, that's a 1911 mag sticking out. The barrel sticking through the trigger guard is a .458" for a different project. The cartridge I call .45Cinderblock in its full house loading. It'll eat .45ACP and .45Super too. I run my peak pressures really high. Flat primers are the rule. With .45acp cases I get 2 firings at full peak power before the primer pockets loosen up. With Rowland brass I don't really have loose primer problems so far after up to 10 loadings. The first set of loads I pulled out and shot last weekend were pretty loud compared to normal .45acp and were clearly loaded in .45acp mililtary brass so my coach notices, looks closer at and says, "What the hell is in those?" So I look at the box, read and reply, "Box says 9grains of Unique in this row and 12 in this row with 200 grain hollow base round nose Bear Creek moly coated lead." And he, a seasoned handloader of .45acp, quietly steps back about 10 feet while I shoot the rest of them. He seemed surprised that I hadn't had a KB on a case head letting go. Then I pulled out and shot a few of the full house loads. They're much louder with a lot more recoil. He was additionally surprised. Will I tell you my load data for the stout stuff? Not publicly but by PM sure.
