I shoot quite a few deer and pigs with a .243 Winchester. My boy uses it quite often as well.

Deer are typically under 250 yards.
Pigs are usually at night and under 250 yards as well.
Go-To load is H4350 and a 105gr Hornady A-Max out of a custom 20” Rem700 and Krieger barrel w/1-8T.
Also use same load out of a 31” barreled rifle.

From my CVA Scout Pistol w/ 1-10” twist 14” barrel, I’ve used the 85gr Sierra HPBT-Game King to good effect.

The .243 has proven to be an excellent low recoil game getter with excellent terminal ballistics. I’ve been very pleased with the the results. One of my favorite cartridges.
