Ok so I know there is alot that can effect things, trying to put the pieces together.

Bullet weight, twist, barrel length, powder burn rate and so on. Have 2 constants, primers and brass.

Here is what I have done.

10.5" pistol carbine gas (less concerned about this one as I haven't really worked loads, just tested loads worked up in carbine)
16" carbine mid gas

Both 1:7 twist IIRC

H335, carbine loves 24-24.5 with 62gr BT

2230, seems lighter loads are going over better for same bullet. Just started playing with this powder today as h335 is gone and got my hands on a lot of 2230.

Trying to break down the basics of how burn rates effected by twist rates, effected by barrel length and so on. Trying to tune loads so they aren't far off from each other down range (or move to specific powder etc for each specific gun, barrel etc).

Thanks
