Load developement for my "Johnny Cash" spare parts 308, input appreciated!
As you all have read before I build some crazy combos, one of my latest is a 308, its a combo of a take off model 10 FCP-K 24" 10 twist on a model 110 7mm mag action, with a bolt face and mag assembly from a stevens 200 30-06, its in a B&C duramaxx olive with black web stock glassed under a Badger Ordinance .320 recoil lug with a modified Rifle basix trigger. It has a 1 piece base and just installed a new weaver V24 mildot with quad lock rings, it had a 6-18x40 buckmaster with weaver tactical rings in the tests I'm about to mention.
So the first load was 155 smk palmas over 49.5grns RE15 in win cases with br2 primers at 2.845 oal .506" 5 shot at 100.
Second was 168 speer bthp match over 46grns varget all else same .428" 5 shot at 100.
Third was 168 NBTs over 46.5grns varget at 2.865" oal all else same .348" 5 shot at 100.
So now all my brass is fire formed and this time they are just neck sized, case necks polished, 20-25lbs neck tension using hornady 178 amp vlds at 2.916" oal jammed .008" in the lands with 47grns varget and br2s, so what do you all think my pieced together toy will do this time? I'm hoping for a .099" 5 shot but I'm sure that's a whole lot of wishfull thinking, lol!

To be 100% honest the stock, trigger, and recoil lug was all that was purchased new, the 7mm action has had 4 different barrels on it and I have no idea how many rounds, the magazine assembly and bolt face from the 30-06 probably had around 2000 rounds in it but all the other things mentioned were leftovers or bought used. I load ammo for people and sometimes like to prove a point, this time I just wanted to see how well I can get leftover "junk" to shoot. It may turn out to be the best shooter I got!
