groups
The first centerfire rifle I shot was a Remington Model 14 pump, chambered in .30 Remington, with iron sights of course. That would have been 1970, and I was 12. The .30 Rem is now obsolete and not mass produced, though I hear you can find some from specialty loading outfits. It produces ballistics in the range of the 30-30 Win. We did not shoot groups. Dad would tack a torn open, empty cartridge box up to the 50 yd backers at the local sportsman club, and I would shoot a couple of shots, if I hit the box, we were good to hunt. We shot a lot of .22 year round though for practice, but not groups. Dad was not going to waste deer rounds on paper......he was raised in the Great Depression ya'know!!!!!!!!!
The next season, my grandfather willed his M88 Winchester to me, and Dad put a 4x Bushnell Banner on it as a Christmas gift. Now I had something. By 16, I'd read enough stuff and could drive to the club on my own, and could buy my own ammo too. Group shooting yielded that the M88 shot 150 gr slugs far better than 180's (1-12" twist for .308 in those days) and began breaking tradition by not shooting .30 cal 180 gr RN like everybody else in the clan. But they shot tighter, and kicked less and I was smug and happy.
Dad still thought it was a waste of money and good shells.
