Your 130 gr. bullet load is quite similar to mine at 3000 ft per sec. But I have developed a new "secret" load at 3200 off the barrel crown that has shown outstanding down range results with a 130 gr. Nosler Ballistic-Tip. Maybe I'll share. Maybe I won't? But it's only fair "I should get someone else's secret load in return. Don't you all think?"
Nice, I'm glad that you're achieving great groups at that velocity!
Do to the platform I'm using, it's an heirloom Browning Safari Grade, I'm not exceeding the velocity recommendations in the sierra manual. If I ever get a newer .270, that will change.
