General Rule for awhile now has been the Xpert is terrible stuff as others have already stated.
IME - the Winchester X22LR is the one - accross the board - in any gun, action type or platform , and accuracy - though it depends works the best "overall" [ meaning if you don't know the gun , grab these]. The CCI equivilent does the same.
Win PowerPoint is the .40 gr eq of the X22lr, Dynapoints and T 22 work. The CCI equiv do the same . Winchester is more readlily avail for me.
Remington has a ammo plant about an hour from me as the crow flies. I've never had good luck with any Remington ammo - except target loads for shotguns. Remington does not make their rimfire ammo btw - I have had terrible results with any type of Rem Rimfire.
The Fed # 550 bulk pack - is probably the best bulk loading out there.
The Marlin 60 - I like. I don't have problems with them, find them to be more accurate than the 10/22. My gun buddy has tweaked triggers and such ...not near as much work ,time or trouble ....runs circles around the 10/22 all tricked and $1k invested in.
I like to use the bone stock ones, I tune in the iron sights and jsut shoot the darn thing. I cleaned the factory lube and stuff , ran a patch down the bore. I then treated the bore with RIG - as I have always done. I have never cleaned the bbl since. I do use a pipe cleaner or q tip for the chamber - if I think about it. I use a pipe cleaner on extraction and stuff , I may even remember to put a drop or two of Keenbore Formula 3 oil ....other than that- I just shoot the darn thing with the same ammo it has always had. Still running, still hitting what aimed at - I have no idea how many rds. We have run 2 bricks in a day through it ....kids wanted to shoot - we let them.
A customer brought in 3 Marlin 60s in for their ANNUAL cleaning , his and the two boys. They purchase by the cases the X22lr and the PP .
I understand saving money to shoot. I don't understand why folks spend money on a nice gun - and use inferior ammo. Be it a $99 MOdel 60 or $4k tricked out race gun. Once one finds the load that runs and shoots the best for task, buy as much as can of that lot if possible. Once I find a load - I never shop around, try another loading, or make a decison based on price.
I pay the monies for the X22lr , the gun also happens to like the Fed #550 ....if it didn't I wouldn't buy it ...I'd buy less ammo quanity for more ammo quality. Just me of course.
