I’m interested in a follow up on this barrels performance. I’m currently trying to decide which route to go for my next build. A PBB 16” 1:8 twist is one I’m considering. This velocity seems really slow, even for a 16”. My current gun is has a 18” barrel and I shot a box of this ammo through it when it was new and was getting about 3100fps.
I expect to see the velocity increase once I get some more rounds through the barrel and also once I start shooting fired brass. Also, I could definitely push a bit harder with the powder but I'd rather not as it will see a wide range of temperatures and a lot of snow/wet conditions.

Got my new barrel from @Unknown Munitions up and running. It’s a 24” ace tikka prefit, tikka lite contour, throated for 88s. Solid turn around time as well from UM, fit and finish look good, bore scoped and everything looked nice and clean on the chamber job and the barrel itself 👍🏻

Barrel shoots well. Initially tried RL26 which produced some blazing speeds but sustained accuracy was not there.

Seems to shoot both 80eld and 88eld well. Two larger groups with the 80s were tiny but with a flier of uncertain cause (maybe me maybe not)…ballistically they are equal the 80gr at 3300 and 88 at 3150fps approx,

Final load is going to be 88eld in alpha LRP with fed 215s, 40.5gr n555 at 3175ish FPS (need to verify velocity tomorrow).

Did you measure your throat with a comparator?
What OAL are you loading the 88’s at?

My upcoming 18” build from them is the same barrel and will be throated for 88’s as well, so curious how that turned out.
