I wished I had found this thread 2 months ago as I have purchased a Sabatti in 450/400 and only had it for three weeks (the usual paper work PTA etc.). Have put a few rounds through it, both factory and reloads and I am having trouble getting it to print both barrels on an A4 page at 25 meters. The crowns seem to be good , certainly nothing like the photos in this thread, however the "V" on the rear site isn't cut in the centre and hasn't been finished properly and has a large file mark on one side. I am hoping that with a little more time spent reloading and developing loads, I can get this thing to shot somewhere on the same page. Having had this experience I am wondering if I should have bought something else. This is my first double, it looks good just need to get it to shoot!!
