I started my hunting and reloading career with a 270, a very inexpensive winchester fwt model 70 XTR - push feed. It was not extremely accurate with factory loads so I took up reloading and discovered that the chamber was factory cut a little large and that the shiny ring at the case head was so severe that I only got 2 or 3 reloads from cases before I had to discard them. With new brass, I learned to fireform them with a long seated bullet. But I also discovered that this rifle would shoot reduced or low velocity loads very well, like consistent 3/8" 5 shot groups. So I loaded a bunch of 2750 FPS 130 Grain bullets and killed everything I shot at. But, in the mid 80's after reading about the 284 Win and it's attributes in a short action, I picked up one in a Browning A-bolt. The factory barrel was outstanding and it was very light weight. Groups averaged under 1/2" and with target bullets 1/4" was achievable. And it liked to the max loads. At about 6000 rounds thru it, the accuracy tapered off and I got it rebarreled with a shilen match and accuracy returned to original. The smith that did the work however, mentioned that the rings were not tight when he was doing the work, so its possible the rifle did not need a new barrel! Now this barrel has over 5000 rounds thru it and accuracy has tapered off. The safe now contains 3 - 284's, a couple of 7-08's and a pair or 280 AI's. My transitiion to the 284 caliber was originally due to the vast variety of types of bullets and weights of bullets. At that time, mono's were just becoming available. Now, I've found that lightweight mono's driven at faster speeds perform very well and penetrate as well or better that the old heavy cup and lead core bullets and shoot much flatter. So that said, I believed with the development of the present day mono's the 270 will just about match the performance of the 284 caliber rounds and component availability is getting better all the time.
I am trying find their max COAL for magazine to see if enough for seating monos out.
Valuable infos there
