I've got a 60's HW35 in .177 that needs help.
Most of it I can address myself, but the bore is "loose".
If 4.53 pellets don't get it back in the game, I'd consider going up to .20 (or even .22) but I don't know of anyone who would rebore to the right land and groove sizes.
Any suggestions?
Thanks all!

Not a process you will find being done ...
If Crosman CPHP's are not large enough ?, Try some H&N 5.54 or 5.55 FTT's

Generally speaking, it's not economical to rebore and re-rifle. It takes specialized gun drills, oil pumps (for the gun drill bits), big lathes, and rifling machines. Far cheaper to replace the barrel.

Thanks guys.
I would definitely want to keep the original, so I'll post on the pellet exchange for some extra large sorted pellets.
Great old rifle, so I'm willing to do quite a bit to help it out. The idea of "upgrading" to .20 was interesting too, but I'd really rather keep it a .177.
Hopefully, the right pellets will show their worth.

What length barrel? I found a 177 carbine length HW35 barrel in the UK. https://www.airgunspares.com/hw35barrel177hw35barrel-177.html (https://www.airgunspares.com/hw35barrel177hw35barrel-177.html)
Yeah, it's 140 pounds, but it could work. Maybe there's something cheaper out there?

That's interesting Bruce, and thank you.
Mine dates to '66 by serial#, not sure of there were any changes along the way...

You would pay a bazillion dollars to have a shop do what you want for just one piece.
