Quick update: I’m approximately as frustrated as I was two months ago.
The gun / ammo is just erratic still. 8-12” wandering groups across now 8 different load recipes using TAC. Have traveled approximate a 2.5 grain range of recipes. Velocities tend to be pretty erratic, lot of times varying 50fps or more over a 5 shot string. Velocity now between 2350 and 2520 has been tried. All using Hornady 200gr SP bullets.
For my typical reloading that seems to be a lot of variation. Had a couple recipes that vary less but the accuracy is still erratic. Have tried C.O.A.L from 2.630 to 2.650. My Speer book says I can go up to 2.680.
Forend removed for all testing, resting gun on receiver only.
I’ve taken to shooting from a Lead Sled. Using a Skinner barrel mounted peep sight and taller front sight. Not the best for sight radius and precision but I’m ruling out a bad optic at least.
I’ve had the buttstock issue a couple times so I’m used to keeping that snug.
I’ve checked and cleaned copper fouling now a couple times. New bore etc.
Maybe TAC powder is my problem? Friend of mine recommends H322 instead. I also have IMR 4895 on hand.
Hate to give up on TAC but I’m tired of chasing my tail.
