How have the 110s performed on game, any experience?

I've shot lots of 6mms, 6saum to 6br. I run 7.5 in everything, but 7.75 in the Saum. I do have a seekins havak 6cm that's an 8tw. 7.5 does everything well, however I am in montana with decent elevation and DA. Shot everything from 90-115 in the 7.5 and all has been well. The most important thing...

I don't like ti but think they are okay to hold higher pressure with 473 based cases. I do have a bat bumblebee and a vampire. They hold pressure as well or better than my steel 700 clones. They also have a steel sleeve in the nose that acts as the tenon and lug abutment, so that's all steel...

It's only high pressure if you make it high pressure, otherwise it has the same saami standards as everyone else. Do yourself a favor and buy an anti-x, Pierce shadow, or pure precision skltn.

Alpha generally does well with their reamers fitting their brass. I have a few alpha reamers, ones a 22gt, their freebore diameter is 225 I that, which is adequate. I'm unsure of their neck diameter. They have generally all been 0045-005 over loaded rounds. If you reach out to alpha, they'd liky...

56gr Rl23 is a starter for 108gr bullets, 59GR H1000, and 62gr N570

If you plan to neck down lapua brass, 257 is too tight. You'll have to turn. I had 2 barrels that dimension. You'll want 225 freebore diameter, and 120 is about right for 80 eldm and Bergers. But 88gr eldm have a LONG bearing. A freebore of 0.190-200 is more appropriate for them.

Have Norma LA mags?

EMC2015 is absolutely spot on here. My chamber designed around adg brass necked down is same spec as he posted. 552 at 0.200 line is essential, and a tight sizing die, tightest I've found is the BC Micron die. Matchmaster close behind. My freebore is 2445 diameter and a mile long as it was...

I see what you're saying, my 6cm shoots well that top node but isn't far from pressure. I have a 24" 6saum, and 109gr bullets get up around 3480 close to pressure with H1000. Rl26 and N565, closer 3550. I run the nose ring cut dtac at 3330 currently with N570, but had it up to 3450fps upon...

Take it this is a barrel nut build since you set headspace. What action? Please post reamer specs. I have a few 22br barrels, run lapua no turn like a champ. Could be a dimensional thing, or not. Peterson/Norma is softer brass. You had to neck everything down initial, what process did you...

Alex has already built a few 25PRC and they've been great accuracy wise. I'd run long freebore and put it on a medium action or one the new bat shorts than can use the 3.150 unknown dbm. I have done 25 Saum, 25sst and currently getting a 25prc done. The Saum/sst were on the same config proof...

22gt will run from an ar15 with light bullets, not with heavier stuff. The BR Variants are what you'd want. However a 473 bolt on an ar15 is trouble waiting, hell even grendel bolts don't hold pressure well. I do have a 22grendel ar15 upper, 25.5gr varg with 77tmk goes 3150 from the 22" 7tw...

Howd the 6mm work out? I know a few guys running standard 6prc and I shoot a 6saum.

Sync the new device to the garmin xero, and disconnect. Shoot a small 3 shot session, and reconnect/sync the new device. All data should transfer over. I've had no issue running the Xero on two Android devices.
