In my humble opinion, too much time is spent worrying about expansion.
Your load shoots within an inch at 100 yards? That's fantastic for a meat gun.
Your load will do the job nicely.
Know your trajectory.
Know your range.
Put the bullet through the shoulder/spine "T" junction on any critter inside 150 yards and they'll drop in their track, and I promise you'll never find the bullet.
My 165-175 grain Seaco/RanchDog/Lyman bullets are cast soft (9 BHN) heat treated hard (22-28 BHN on LBT tester), gas checked and lubed with whatever, loaded over 25-26 grains Reloader 7, and shot from ancient Marlins with open sights, or newer micro grooved 336s.
All fully penetrate 200+ poung pigs though the shoulder, though grissle plate, shoulder blades, and spine bones.
With this shot placement, I've never recovered a bullet, never had to shoot twice, and never had to chase or track a critter.
You have done your homewwork and testing. No go proove it to yourself.
Once the first trigger is pulled and the critter is pounded with authority, your confidence will replace the worry about performance.
GIT after it! Go shoot a pig!
