Sudesh,
This is my Ruger M77 in .280 Remington. It was one of the first rifles that I ever bought and is still my favorite. It would regularly clover leaf at 100 yds with handloaded ammo. The area that I'm in now doesn't allow rifles during deer season so I haven't done any serious range work with it for a while (or reloaded for it lately). I was in college when I bought it and all I could afford then was a 3 X 9 Bushnell scope. However, the scope has worked out well enough that I never changed it. It is one of the older Rugers with a tang safety and fully adjustable trigger (crisp!). A Ruger at that time could be kind of hit or miss but I got lucky with this one. They used to buy their barrels from many different sources and consequently one could get a sweet shooter or something that performed abysmally. Ruger now makes their own barrels and quality is more consistent from what I hear.
.280 Remington, which was also called 7mm Express at one time, is nothing more than a 7mm bullet in a .30-06 casing. It does have its shoulder moved up so it will not chamber in a 30-06. When Remington introduced the.280, it loaded the cartridges down a little, so they would not pose a hazard when fired in the model 742 autoloaders out there. In a good bolt gun, the .280 can be loaded to perform significantly better. Even my milder handloads (using 139 grain Hornady BTSP) used to give me about 3000+ fps. The advantage of the .280 over the .270 is the wider range of bullets that can be used (from 110 gr. to 175 gr.). So your loads can be tailored for a wide variety of game. However, you will get a lot of arguments about that

.
As you can see it has a heavy barrel, which helps in the accuracy department. The overall weight of the gun and barrel is relatively high for a hunting rifle but that really tames the recoil. My daughter who is about 5ft 2in has fired it without any problems. There is pressure applied to the barrel at the fore-end so I don't use the sling for shooting. The sling is just used for carrying so I never bothered with anything but a cheap one.
The cartridge shown is a 140 grain Federal Fusion.
