7 mags, 300 mags and more obscure cartridges. Around hunting season Wally World has Remington 150 gr, 165 gr or 180 gr CoreLoct ammo for about $16 a box, and those loads are suitable for any game in the US.
Hope you're good thackney.
I seem to find Core-Lokt $18~19. While it is cheaper than the more powerful mags, I find it typically a bit more than the non-magnum calibers often used.
I did choose the 30-06 for my first center-fire rifle due to the wide range of abilities in the available ammo.
I like buying the Golden Bear for entertainment at the range. It gives an attention getting bark and is still visibly flaming coming out of the barrel if you watch it.
Be well, God Bless
