Thread: sub loads, accuracy, sd goals etc

So, im loading some sub sonic rounds , 280gr peregrines into my 338Federal, I am using 15.4gr of n110 which gives me 1100fps almost bang on and once the projectile is seated, the old "shake the case" test sounds like its pretty close to full capacity.

What sort of "groups" and SD, is expected for a subsonic load, im guessing due to these only really being efficient out to 150m, im assuming about an inch @ 50M is tolerable? and again, assuming SDS arent goign to be amazing, but as long as they are at the lower end of the sound barrier then it should be good ?

Wanting to head shoot deer with the thermal gun and subs 50-150m - So just trying to work out whats good for sub loads.

additionally, Im having trouble with my frankford thrower throwing n110 being such a fine powder - anyone found a fix for this lol possibly enlarging the hole in the pickup tube ?
