Bullets too long?
So I shot of the first of my 22-250 handloads the other day. Of all things I was expecting and watching for...something caught me off guard. I wish I had pictures but I'm gonna have to try and describe what's happening. (60 partitions are being used)
I did the little deal where you take a dummy round barely seat the bullet and then chamber the cartridge to get an ideal of your max overall length is. I did this and it can out alot longer than I was expecting so tried it again with another dummy long-round, same thing. I certainly didn't feel comfortable leaving bullets ANYWHERE near there so I looked as some factory ammo and set the bullets about 1/4 of the difference between factory and my crazy chamber-dummies longer. (does that make any sense?) I'm working w/o a micrometer right now so I can't just throw you guys a number.
Anyways, my groups were fine and no pressure signs I knew of BUT I think my round is still too long though I can't see how. In the 700 action there's a round button that contacts the case's base at about 7 o'clock and this is shearing off tiny amounts from my cases. Can this be anything besides OAL being too long? The ammo feeds fine but at the end of the "stroke" when you have to rotate the bolt there is a slightly noticeable increase in the needed pressure. The cases were once fired. Is the 22-250 a caliber you must trim between every loading?
