Re: RELOADER 25 DATA=Please Help

for a 300 win 75-76 grains is correct for rl22 and a 180, so I'd say you can hit 80 or so of rl25 easily and more with a long throat. I use rl22 with 165 hornady's in my browning at 78 grains with a 215, and it is great with 10 shot moa 100 yard groups as fast as you can aim.
rl25 hasn't changed much since introduction; the same loads with powder with the "new" logo on the powder were still working with my old 7 stw with new powder at the same pressure/vel. this last year before I traded it this spring. Wish I had that pipe back.

You could buy a hogdon manual or the sierra as they seem to have more listings for other powders.

RL-22 has been the go to powder for me in the 300 win. I may start with a diff powder, but I end up on RL22.

Thanks Guys,

I have both Hogdgons and Sierra manuals but looking for similar data for RL-25

I have used H1000 with 165G interlocks with good sucess

I may try RL-22 or H1000 with the 180's

and I will start well below the max with RL-25 to see what works.

Thanks again,

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.

Has anyone come up with a formula for 210 Sierra match Kings with reloader 25?
