For consistency you should use the same caliper when making adjustments and measurements. IMO

I think that was an attempt at humor?
My advice is to go buy some factory ammo that says "270 Winchester" on the outside of the box. It's the only way out of this!
Ok, moving on. The only measurement I'm going to use is the pic you sent with your digital Caliper. I don't feel safe going back and forth with different calipers.
Take your CBTO measurement of 2.805 and deduct .020. This gives you a CBTO of 2.785. Make a dummy round at this length and check to see if it fits your mag well and then check if it cycles. If it does you can start here. If it doesn't back off another .020 to 2.765 and repeat. Report back your findings if you want to continue.

I was having problem getting the display to show the numbers that why I switched.
See post #200. Start there and make a dummy round like I mentioned. Does it cycle and fit in your magwell? if it doesn't, You can then adjust your die to seat bullet deeper .020 if needed. All measurements using CBTO and your digital caliper. Report back. I think you're going to find you can start working a load up in the mid 40 powder charges. Just because you may have a lot less powder isn't a bad thing. Guys are running the 170 Berger's with mid 40 and low 50 charges.
What caused my problem is I thought I could use lead bullet load data. Less powder and longer OL and I should be good to go. Thank you all for the help.
Did you get it to cycle and fit your magwell. If so, start with low powder charges and work up. Patience, doing things consistent, is of the utmost importance when reloading. Go slow, most mistakes are made when we rush and get frustrated. Suggestion- Only use one Caliper and buy a good quality one, I prefer digital. Always double check your math as it's very easy to make a mistake. Good luck!
PS- let's us know the muzzle velocity you get on that new "coronagraph"! Just messing with ya.
Yes it will fit my mag. Winter has come back to up state NY so it may be a few days, yes I am living behind enemy lines.
