Honestly, I neither love or hate the 270 Win. I have owned rifles in 270 Win, but did not acquire my first until 1999, or take game with one until the same year with that firearm, a left hand Rem 700 LSS. It produced sub-MOA accuracy with Federal Premium 140 gr ammunition, with both the Ballistic Tip and Trophy Bonded Bear Claw bullets. I took mountain goat, mule deer, caribou, and moose with that rifle before selling to an acquaintance looking for his first hunting rifle, and so I could fund another rifle.
It is a great cartridge design that has fulfilled its potential and provided decades of reliable service for generations of hunters.
I was somewhat soured by the constant arguing of my father and uncle over whose rifle was better; my father's 30-06 (another cartridge that has also provided decades of reliable service), or my uncle's 270 Win. (I have owned 30-06s too over the years, and actually took my first moose with one in 1989.)
When it came time for me to buy my own first rifle, I chose the 280 Rem in 1992 instead and have grown to be a fan of this tweener that has been down played by many, yet has earned its own fans amongst knowledgeable hunters, shooters, and riflemen. I have owned a few rifles so chambered over the years, and now finally have a semi-custom LH Rem 700 XCR that has both the original synthetic stock, and another LSS stock, both of which have been glass and pillar bedded so that POI does not change when stocks are swapped for fair vs poor weather hunts or hunts of easy vs rough terrain. The rifle will produce .500" accuracy with Federal Premium 140 gr AccuBond ammo, which has accounted for elk so far, and I will be developing a load for the 150 gr AccuBonds and Ballistic Tips for it.
While both work well, I have just not developed a fondness for either the 270 or the 30-06. And can say the same for the 308 Win, another great cartridge that has performing well for many, for decades. All of the rifles in these 3 cartridges have either been sold, or rebarreled to other more interesting cartridges to me, over the years, where I enjoyed the rifle platform, and chose to keep the rifles for other cartridges of the same action/case length. I will say that of the rifles in 270 Win, I have enjoyed the hunts that I had and the game that I took with this cartridge. It performed well, and did what was expected of them.
My daughter chose a rifle in 270 Win (Rem 700 Titanium Gen 1) when given the opportunity to shoot several different rifles chambered in various cartridges from 260 Rem to 358 Win (which she shot her first big game animal with (mule deer). She produced 1" groups with Federal Fusion 130 gr ammo, and liked the weight and handling characteristics of the rifle, and its manageable recoil, as compared to the other rifles and cartridges tried. She has taken moose, mule deer, caribou and stones sheep with it since then.
Other 270 caliber rifles I have owned and enjoyed over the years include those chambered to the 270 WSM and Weatherby. The smallest group I have ever shot with a centerfire rifle was with a Winchester Model 70 XTR in 270 Wby with a handload shooting the 90 gr Sierra HPBT at 0.181". I have taken coyotes, mule deer, moose, and my first elk with the 270 Wby and will always have a soft spot for this cartridge. The fastest cartridge I have ever shot was a 110 gr Barnes TTSX load at approx. 4000 fps from a Browning B-78 rechambered to 270 Wby with its 28" barrel (Chrony failed for last two handloads up to max, with no pressure signs, after reading over 3900 fps with 1 gr below max). It too, produced groups that were sub-MOA.
Today, I still own and enjoy my LH Browning X Bolt All Weather in 270 WSM. It shoots the Federal Premium 140 gr Trophy Bonded Tip ammo at 3156 fps, and produces 3 shot groups at 100 yards of 0.396". It will also shoot Nosler's 140 gr AccuBond ammo at 3073 fps and produce 3 shot groups of .565" at 100 yards. Not too bad for a caliber that is not necessarily known for its accuracy! With a Leupold VX-III 4.5-14x40 B&C scope mounted in Talley one piece rings and bases, and a full magazine, weighs 8 lbs 1 oz. It carries, handles, and balances well when shouldered, and has accounted for a caribou so far.
