Congrats cpt dan, you found a good one [got a couple myself] [actually too many] but is it a real .45 lc or a drilled /rebated .455 webley caliber? If it’s a real long Colt you did super. If it’s been altered youl need to find some .454 or .455 dia lead bullets to load in your long colt brass for it to shoot the best, .452s are a tad too small. Here’s my last Colt New Service 7.5 inch bbl chambered in .38-40. A real good shooter. Always wanted one with the long bbl. By the way, trigger pulls on these old Colts can be tough but you can swap out the mainspring with an official police or python mainspring. Makes a big difference. Enjoy.
