Funny you should say that, my first real rifle was a Ruger M77MKII stainless .270win; and I tried every bullet I could get my hands on and some shot better than others but all under 1.5moa and most under 1moa and Accubonds and Interlocks would cloverleaf.
I learned a lesson when I ordered 200 140gr SST bullets thinking “these will be accurate!” Wrong! The SST was the only bullet that rifle hated and no matter what powder or seating depth it would not shoot under 3” and thankfully was able to trade them for 140gr BTSP Interlocks.
