I have had my UL Mark V for 12 years now in 3oowby. For the first few years I always had problems finding a load and had a lot of flyers. The only way I could get good grouping was loading very light loads of 18ogrn. Down around the 2900ft/sec range. Total junk for a wby. After the 4th year of owning it, i removed the pressure point and bedded the action. Wow, what a difference! Removing the pressure point turned it into a sub moa shooter.
I have been shooting 18ogrn TSX @ 3150ft/sec for the last 6 years now and get .5moa grouping all day long. I now shoot out to 800m with confidence. With the light barrel, i still watch the heat build up, but that should be a gimme with any UL rifle.
