I've been shooting 300gr bloodlines (.50 cal sabot .458 bullet) for three years now and have always gotten under 3" groups with open sights at 100yds, 1 1/2" when I'm shooting well. It was shooting this well a month ago when I shot it. It's a .50 cal knight disk extreme with the western bolt. I'm loading 100gr 777ffg loose with musket caps.Well I went out today and eight out of ten shots keyholed, and the shots were everywhere making about a two foot group! The two shots that were clean through paper were about 2" apart a tad low but in the bull. This was on a tight full set of sandbags. I stopped shooting so I didn't waste anything. I clean my gun every six shots. Every bullet was seated well and the gun was going off like a mod firearm, zero lock time that I could notice. The stock is tight, the end of the barrel looks clean and undamaged. I'm not sure what else to look for. I'm going to try another load I've had luck with to see if its the gun or the load. Anyone have any thoughts as to what's going on? Thanks.
Thanks guys for trying to help!I dont think its bullet weight either because the same weight XTP's shoot very well. I really liked the bloodlines and they shot great for 2 years, I have no idea what changed. next year ill start from scratch and try to figure it out.
