Re: RELOADER 25 DATA=Please Help
I tried RL25 in my .300WinMag with the 190gn SMK's and WLRM back on 02/22/2009. I loaded 75.0 thru 77.5gn in half grain increments, 3-shot groups. The best I got was .510", average of 3021fps. The outside temp was 40*.
Never did find a good load for my .300 with RL25, but used it in my 6.5-284 Norma to shoot some impressive (< 2.0") groups at 500yds, with 120gn Nosler Ballistic TIps.
I tried H1000 in my .300 for the first time in Aug of 2010. I used the 190gn SMK and CCI 250 primers. 79.0 thru 80.5gn (1/2gn inc.). Best accuracy was 79.0gn (.142"), velocity was 3078fps (avg). Just an FYI, 80.5gn shot a .4185" at just over 3200fps. Think chrono was acting up for the latter load. Sun was fading fast. This powder has worked well with the 180gn Ballistic Tip, 180gn MK and 185gn Berger.
I also got good accuracy from 75.5gn of RL22. This proved good with the 180gn MK and BalTip both.
Hope this helps. JohnnyK.
