RL-19, as much as your gun will take.............usually about 2950'ish.
For 250's, RL-22, again as much as your gun will take for about 2700'ish.
Can’t help you much with the 210’s....but getting 2950 with 225 TTSX’s in my wife’s .338 ( Win. Model 70, 24” barrel). memtb
That's gotta be warm............2950 with the 210 is not a wimpy load.
