Reloader 23 works very well for me in both a Remington 700, and a beautiful model 70 Supergrade, both in 270 Win. Its a temperature stable powder that has proven to provide very good velocity and accuracy in my rifles. I used to use Reloader 22 until I did some temperature testing and discovered that it suffered from some rather extreme velocity spreads at different temperatures. I repeated these tests using 23, and found that it virtually eliminated the problem. I also use this powder in my 6.5 x 55, and 300 Weatherby rifles with very good results.
