Just a random question. I got a Wilson combat barrel and came with a headspaced bolt but no firing pin but I have a spare Toolcraft BCG and was going to swap out the bolts to match the WC barrel. The Toolcraft has a smaller diameter firing pin hole but from the eye the WC bolt appears bigger like a standard firing pin will work. When I measure the diameter of the bolt holes they are about the same so it’s throwing me off if the WC bolt needs a smaller diameter pin but maybe I’m measuring it wrong. Seeing what you all thought if I needed to ordered a standard firing pin (I don’t have one on me) or will the smaller firing pin work for both? Sorry prob a dumb question.

Pin gauge to measure. Your calipers cannot measure the diameter correctly.
If I had a dollar for every time I’ve see people on the hide incorrectly measuring with calipers, I wouldn’t be rich but I could take us all for a nice sit down meal at Applebee’s. 🤣

But yes, pin gauges is the would be the preferred tool. 0.0635±.0010 is the TDP spec if I remember correctly.
