Are you sure the reamer is what its suppose to be? Maybe some measurements are in order.So I started cleaning my barrel and I decided hey I haven't measured my necks in fired case for awhile. I'm getting for most cases .3405 and putting a bullet in a fired cases I have to really twist and push down. So maybe I do have a carbon ring or a very tight neck.
I think someone else mentioned using Alex's method so i cant take that creditI put my other barrel on that is throated for the berger 245s oal is 3.750. 30 inch bartlein n565 I know it's slow but been shooting lights out. The few bullets that are off a little are mostly from me. Adjusting to the recoil of the 245s vs 220s in a supressor was different and the barrel isn't as heavy. Good news is I finally figured out my issue. Embarrassing but it was a sizing issue because my so called .02 shoulder bump wasn't .02. My SAC headspace tool doesn't go down to shoulder and was throwing my numbers off. I thought I did Alex Wheeler method but I guess I didn't and messed that up. So my brass number at 2.0445 has a slight drag tap with finger to close easy with plunger out of bolt. I sized it to 2.044 and it closed on its self from there I took .02 off and got my true shoulder bump and have tested it with good results. I wasn't getting any shoulder bump so the brass had nowhere to grow. It was a foolish mistake but learned a lot with these tools DONT TRUST them do it Alex way and it's fool proof. I thank for all the advice. @Ledd Slinger you asked if I used the method and thought I did but I messed up thank you for info and advice.
That’s impressive! Close to the charge weight where N570 shoots really good with the 220 and 230 as well245LR

Destroying targets 24x24 at 2600 yards. Absolutely dominating. 245 being push that fast BC goes up even higher, not looking back at my 33XC this thing is laser!
Twist barrel? Jumping or jam?245LR

Does anyone have a Go-Gauge for Alex's publicly released reamer print that I can rent or buy? JGS has a reamer ready for me, but the corresponding Go-Gauge is 3 months out. Thanks for your consideration.

Thank you, PM sent.The proper way to chamber this is with a crush fit on virgin brass. I know how short to hold them with my gauge but you dont need a gauge.
