You're trying to get me to do something that sounds like work?Grumpy wrote:You have a .280 Rem ?
VERY under-rated cartridge and one I`ve never shot because it is a rare chambering here.
How about starting a new thread giving your impressions of the cartridge from a user perspective.
You want me to get out the chrono and load up a bunch of cartridges and actually write a report?
Oh! The effrontery!
Well, I had planned to do a post on the rifle someday and I was going to say something about the cartridge at the time.
Just haven't got around to it. I'll get to it ..sometime, I guess.
In the meantime; a few comments:
Pros:
1. Uses 7mm bullets; of which there are a very wide variety available.
2. 7mm bullets are also more aerodynamically efficient than .30 cal bullets of the same weight and shape.
3. In a good bolt action rifle, this cartridge can be loaded up, close to 7mm Mag specs.
2. The casings can be made out of .30-06 brass (in a pinch.. not that I would want to.)
3. SAAMI max pressure is 60,000 psi
4. It can be loaded with lighter bullets than a .30-06 (without a sabot) and with heavier bullets than a .270. This is one of its niches.
5. It shoots flat, flat, flat with lighter bullets.
Cons:
1. You need a long action rifle to accommodate this cartridge.
2. Over the counter ammo is not as readily available as .30-06 or .270
My favorite load is a Hornady Interlock 139 gr. BTSP making 3000 fps at the muzzle. A light recoil, flat trajectory and that bullet is lethal on Whitetail (approx 2800 ft. lbs at the muzzle and 1500 ft. lbs at 400 yds).
Range estimation? Who cares?
Sighted in to zero at 200 yards, you can hold on the top third of a deer's silhouette out to just shy of 400 yards.
With this zero setting, the bullet never rises more than 1.5 inches above the line of sight.
Any further than 400 yards (or even less today, as I get older) and I will probably have a hard time telling if its a deer or a cow.
I've shot up to 165 grain bullets in it but there are heavier bullets available.

Reloading for the .280
I actually find this a very forgiving cartridge to load for. I have been reloading for this rifle with a Lee Loader kit. The kit does well enough that I never bothered to get regular dies for it when I did get a press.
Hey, this is just one of my hobbies. Besides that, at my age, hunting has lost a lot of its charm, especially during a Northern Minnesota November. Here it is Shotgun only for deer.
Using the Lee Loader.
It is possible to make very accurate ammo, even out in the field, with this simple kit.
I was a poor college kid when I started reloading for this rifle. I couldn't afford a press back then. In fact, during my last semester in College, I was so broke that I sent my guns home with my then girlfriend so I wouldn't be tempted to sell them.
I bought this simple kit in 1984. This ingenious kit allows you to use a hammer (Yes, it can safely be used with a nylon faced hammer!) and the "Lee Loader" die to deprime, resize the case, re-prime, seat the bullet and finally crimp the bullet in place after adding the powder with the dipper. With a little practice, It is possible to throw a very consistent charge with the dipper. Unfortunately, it is no longer made in .280.
When I first got the rifle, I assembled a longer than normal cartridge and blackened the bullet with a marker. I then closed the bolt on it. After pulling it out, I used the die to set the bullet a little deeper in the case. I kept doing this till the rifling no longer marked my bullet. This gave me a final length that set the bullet very close to the rifling without touching it. The die has fine threads and can be adjusted with a great deal of precision. I do not use the dipper anymore. An electric scale allows me to experiment with a wider variety of charges than the dipper allows. This kit is meant for a bolt action rifle as it neck sizes only.
Measuring the powder is what takes the longest time. If you use the dipper, you can whack out (pun intended) the cartridges quite fast.

Lee Loader instruction sheet
The rifle is an old Ruger M77 with the tang safety. Back then Ruger rifles came with a fully adjustable trigger.
This particular rifle has a 24" heavy Varmint contour barrel which is unusual for this caliber.
It took months of scrimping and saving to purchase it, used, for the princely sum of $250 (in 1984).
The scope is just a cheap Simmons 3 x 9. It was all I could afford back then.
However, every time I test it, I find that it hasn't shifted zero since it was first set up all those years ago. Why change something that works?
Yes sir, the .270 and the .280 are close, performancewise.TwoRivers wrote:From a handloading user perspective, .280 Remington, .284 WCF, 7x64, .270 WCF...four peas in a pod.
You don't want to say that out loud though, in some parts of this country you could get scalped for that kind of blasphemy.
Each cartridge has its adherents and their faith in the efficacy of their chosen cartridge rises to the level of religious fervor.
One anecdote tells about how even the Elk know that it's useless to resist when faced with a .280.
It's about this Elk Hunter who, every year, just goes to the foot of the mountain and yells at the the top of his voice that he has his .280 with him.
In a little while, some packages come rolling down the mountain, already quartered and packed....
He pats his rifle, picks up his meat and goes home.
