I have just begun reloading and loaded my first loads for my 18" barrelled 7mm-08. I bought about 200 140gr 7mm projectiles off trade me with about 120 of them being hornady interlocks and the rest nosler bt's, so the noslers were the first I tried. To find the amount of powder to use I started at the min load of 38gr, then did a 39gr and stopped at 40gr where the pressure looked good but I didn't want to push it further.
I loaded these 4 seated at an oal of 2.75 inches with 40gr of Ar2206h. I used my neck sized once fired hornady brass.
These were the results at 100yards resting on my bag and jacket the same way I would shoot when taking a long shot hunting.
I pulled the last shot but other than that I was pretty happy, I don't think I will bother with ladder testing since I can't shoot much better than that.
Now I just need to zero them for 200m and by doing this I will roughly calculate the velocity.
