A few years ago, I bought a 1980's vintage 110LH in 308 with the intention of swapping barrels. I made the mistake of shooting it, and thus used it for a couple years deer hunting.

Over time, I acquired a new 24" 358 barrel and a take-off 22" 243. About 3 weeks ago, I decided to actually swap barrels. After much anxiety, it took me about 15 minutes with a Wheeler barrel vise, an ebay nut wrench, the wood blocks and some rosin. I now have a 358 bolt rifle in left hand, unobtanium on my budget. Whe I get old and feeble, it will be a 243.

Love it when a plan comes together.
