My first rifle at age 18 was a .270, Remington 700 ADL. That was 39 years ago. It is still in perfect condition and drives tacks.
My first rifle at around 6 was a Remington 512 in .22. At 15 I picked up a Glenfield 30-30 at FedMart for $58.00. The next year a Remington 700ADL in 243 from Foleys for $99.00 some 47 yrs ago. As I’m always tinkering, I first rebarreled the 700 in 308( several different bbls). It’s currently sporting a 6.5x47 Lapua bbl.
I gave my BDL to my SIL. My 7600 shoots touching holes with my reloads. I have a Tikka Intercontinental I used to shoot Metallic Silhouettes with with a Leupold 4-10. I used to load down the closer targets to .243 speed. Full load .270 is a beast. I gave some thought to shooting the Intercontinental in Long Range Hi Power F class but never did.
