Alright...I've seemed to confuse the hell out of myself. I asked my father to measure the OD of the pilot and that's the number he gave. I knew he was confused when I asked him to do that for me. Also, I have the steel pilots not the carbide ones. I have the whole set of expanding irons and pilots. The only issue is that they only go to 338 caliber. I have a email into K&M to ask what their suggestion is. I did see on sniper-hide that someone else had the same problem as myself. They told him he needed the larger Turner...the one for the 50 bmg. Apparently that Turner will accommodate the 375 pilot. I want to hear that from K&M directly.
Tom, do you have a 375 pilot your using from K&M? And if so, did you need the larger neck Turner to do so?
