Alliant shows 91.5 grs RL25 as max with the 200 grain Swift A-Frame (3020 fps)

Hodgdon shows 92.5 grains H1000 as max with a 200 grain Nosler Accubond (2975 fps). H1000 is a tad faster burning than RL25 so in theory you could exceed this charge if using RL25, but start low and work up slowly. Use a chronograph if you can, they sure help. Look for about 3050-3100 fps with a 26" barrel and 200 grain bullet for a safe max load with the slow burning powders

twist rate was a 1:10

starting load
RL 25- 79.0 grns = 2768 fps
max load
RL 25- 88.0 grns = 2981 fps with a load density of 90%

the fastest max load is magnum powder with 97.0 grns = 3051 fps load density of 92% and
also US869 with 104.0 grns = 3051 load density of 97%
