Shotgun slugs work, work well. They're just different.
If my state goes full on HP rifle I'll probably run the .35 Rem untrimmed.
My shot situations are under 200 yards.
I might even go lesser, try .256 Win from a TC Custom shop rifle.
But that'd be up close, antlerless.
I'm not so much a cartridge guy as platform dude.
I like cool guns.
Have had 3 auto '06, a couple of pumps, 7mm and .300 mag, 7mm O8 and over a half dozen .243's. Plus theres been a few other varmint rifles around.
Three lever guns, am no .30-30 fan. That old crappy .307 really probably soured me on all of them. It was a beautiful gun.
Oh yeah...........accuracy.
My 742 Carbine (minty older model)...........shot my first shot cold bore to 1" high at 100 yds. Every time..........let it cool, shoot...........1" high. No left to right issue. Wonderful.
Well maybe not. If you shot 5 shots the first from cold bore was 1" high, the next 4 were in a 1.5" group............not bad.
But they were 7 or 8" lower than the first. Yup, bbl heat up, gas block welded to underside. Barrel would warp.
Now there might be some validation for old timers running see through rings on these old 742's. Like Mini 14...........when the bbl warps if using iron sights, your sighting system moves with the warp.
But if you run a scope, it won't.
So a first shot w scope, and followup with irons might put shots in same general area. Of course the see through rings and crappy cheekplacement cmight induce enough error to be worse than if you just kept blasting through the scope. Dunno.
The true solution was to use scope and know the change and adjust for it.
7 or 8" at 100 yards is substantial IMHO. Enough I sold the pristine rig (now I knew why it was in such good shape).
Odd, I got two beater 742 regular models and they did not shift with bbl heat up.
I wouldn't mind a Model 6 (pimped 7600) carbine in '06............free float bbl, pump rifle doesn't bother me.
Had a Marlin in .44 mag...........eh, I like a Ruger auto in that cartridge better. Doesn't shoot as good as my Marlin did.........but a fingergroove Ruger like new is just too cool. I got one deer with it. I'd call that gun a 4" at 100 yards. My Marlin did 2".
Perfectly content to use the less accurate rig within its limits.
Because I have multiple rifles to choose from.
Use whatever makes it fun
Slug guns fall within that
Esp if you grew up in a shotgun state and had success. Good times. I thoroughly enjoyed going old school back in '06. Might do it again, never know.
