Thread: 300blk Loading Tips

I know there is a fair bit of info on the forum already (I've been searching through all the threads) but most of the reloading info is spread through multiple threads.

I've bought a Howa Mini action 300blk and wanting to set up a few different loads, unlike most cartridges there is an insane variety in projectiles, powders, seating depths, and rifles the 300blk is used in so there seems like no obvious load to try as a first step.

I'm planning on using 2205 and will obviously work up my own load but is there a seating depth/COAL that is a good idea to try?
Usually I'd try mag length or .020 off the lands but depending in the projectile these two measurements will vary widely.

I've got some 190gr Subx bullets I want to try and will get some 125gr TMKs. I also want a cheap subsonic load I can use for long range plinking, probably with 150gr bullets.

Any info you guys can share will be greatly appreciated.
