I had a Tikka M55 SS that a dealer with a bore scope told me was in need on rebarrelling.Does it shoot straight?
If so, why change anything?
A borescope will almost certainly tell you that you need to spend a lot of money, but your zeroing targets may well tell you otherwise!
Try the ppu 80 or 90 gr my old .243 liked themLincolnshire, it's currently 22" I believe. I use it for fox mainly but also roe. Fox I use 58gr vmax, and 90gr Sako for roe although I have to keep it closer with the heavier bullets as I've not found one it really likes.
Sorry just seen this. That crown looks OK from the photo but I think I can see some rough spots near the top and bottom. Can you feel anything unusual when running a fingernail around it? You could try DIY lapping with a ball bearing and some lapping paste. Personally Id do this, then deep clean, then re-foul the barrel with your current ammo, then try a few other types of ammo. All this costs is the price of ammo and all practice is helpful.It's hard to get a decent photo, rifling is noticeably thinner the last 1-2", also if I was to guess I'd say the pitting is the last 2-3"
Hell, if you saw the state of my 6.5x55 barrel from 1986 you’d wonder if it could group to a size of a4 paper with the pitting! Like a drainpipeI think I'm gonna have a clear out and get a pre-owned barrel put on it for now.
I stripped it down last night and had a proper look down it and it's got very light pitting at both ends of the barrel and the od spot in the middle so I'm only prolonging the inevitable.

I shortened my 243 sako 75 many moons ago wouldn’t recommend it I’ve since had it rebarreled with a 1in 7 twist at 23 inch.Hello all again, well i got hold of a chrono and here's the results for the 243 some shockers here! the ft/lbs data came from strelok the chrony is a gamma master chrony which was set up approx 16 feet away from the muzzle-
