I've owned two .270's, both Mannlicher-Schoenauer fullstock carbines with 20" barrels. I had two loads, one used the 130-grain Nosler Partition bullet with 55.5 grains of IMR 4350, and the other used the 150 grain Nosler Partition with 53.5 grains IMR 4350. I zeroed these rifles to hit +4"@ 100 yards. They then hit +4" @ 200 yards, and 4" @ 300 yards, and BOTH BULLET WEIGHTS shot to essentially the same POI at 100 and 200 yards. (A known propensity of the .270 Win., and the .375 H&H as well.)

The last .270 M/S was one I bought in 1964. After mounting a Lyman Alll-American 4X fixed-power scope on it and zeroing it in 1964, every year after that I'd fire ONE ROUND each fall to check the rifle's zero before hunting with that rifle. I sold it in 1987, and when I sold it, it was still shooting to the exact same POI it was zeroed for in 1964! In all those years, it NEVER CHANGED zero - what a dummy I was for parting with that rifle!!!
