[QUOTE="cabelasken, post: 2279746, member: 117774"] About 40 years ago the first rifle I purchased for myself was a 270. It was a nothing fancy model 70 XTR push feed. After a year of trying to develop loads for it I discovered that it preferred light loads or anything under 2750 FPS with 130 grain bullets. I also discovered that the chamber was cut a little over spec and if I did the typical resize, brass life was only 3 or 4 firings. So, I backed off the resize to just touching the shoulders and got a little better case life. So with once or twice fired brass, neck sized only, and loaded "down" to 2750 I got 1/4" 3 shot groups and 3/8" 5 shot groups. The only thing I changed on that rifle was installing a Chet Brown fiberglass stock and carefully bedding it to 2" in front of the recoil lug. I honed and adjusted the trigger assembly so it was extremely smooth and broke at exactly 3 lbs. It killed every game animal I used it on out to about 350 yds with one shot. But after 10 years, I decided to change over to a Browning a-bolt in 284 win which loved hot loads.I have now gone thru over 10,000 rounds and two barrels on it and now in need of another barrel! Now there are many more guns in the safes and all have a purpose. I love em all!!! [/QUOTE]
