I haven’t been visiting the handguns side of THR much lately, but I’m sad I’ve overlooked this thread for a few months.
For revolvers, a 357mag is the easy button, I’m partial to Rugers, but readily acknowledge they will need sear work done to feel the way they should for proper king range work.
I personally do most of my long range wheelgunning with a rebuilt original 6 shot Ruger Redhawk 357magnum, reamed to 357/44 B&D (44mag case necked down to .357” bullets). Laying on the gas, or H110 rather, I can get a drawn 180grn Speer rifle bullet up to 1900fps in the 7.5” barrel, and getting out to 250-300yrds from a support is bread and butter. Leupold VX-3 2-8x on top most of the time, but occasionally a riflescope.
For sublime enjoyment, a Ruger 10/22 Charger is hard to beat. 6” falling plates in 10-15 seconds at 50yrds is literally child’s play, and hitting 3” wide prairie dogs at 200yrds is the game. It holds about 8” at 325yrds with cheap, bulk box ammo. Notably better with Eley Club.
Shown here a couple years ago with a Nikon Buckmaster 3-18x on top, since replaced, shooting 8” and 10” gongs at 325yrds.
A few weeks ago on Easter Sunday, my 7yr old son warmed up for longer range work with relays on the 6” falling plate rack at 50yrds - clearing in under 15sec par time. Now sporting a SiCo Warlock and a Bushnell DMR II 3.5-21x rifle scope. He spent the rest of the day practicing wind holds at 200 and 300yrds on 3” wide prairie dogs, 5” square, and 66% IPSC’s (12x18”) in 20-24mph wind.
