[QUOTE="Moman, post: 346697, member: 10494"] JE, thanks for the reply. I'll have to admit, I was pretty excited when I measured the first couple fireformed pieces. It's got a real nice chamber in it, a little much freebore, but I figured it would. I have always been a partial FL sizer, usually going about .001-.002. Today I played around with my sizing die and set it to push the shoulders back .001 to 4.465 and they feed into the chamber quite a bit better. I feel a little better having a bit of room for a hunting rifle. I didn't expect that much spring back, I'll see what they come out at with the new shoulder sizing. Anyway, the gun really shows some promise. I did a good break in and thoroughly cleaned between each round for the first ten. Very small amount of copper fouling and the first three shot .5 Worked on three shot groups yesterday and it opened up a bit to .75 but should come around. Trying some 200 AB's tomorrow. [/QUOTE]
