Ok, so Ive reloaded .308 Winchester for a little while now and have found that my rifle, Remington 700 SS 5R MilSpec, seems to really like around 43.0-43.5grs of IMR4064 with Winchester WLR Primers and Sierra MatchKing 175gr HPBT with Lapua Brass. (Fyi: I havent really loaded hotter than 43.5 because I dont want to get these loads too hot and again, it seems to work, but thats the hottest ive gotten to.)
Now that Ive gotten happy with the accuracy of this load with just using the book reloading specs, I want to tailor a round specific for my rifle. Following are the measurements I have from my chamber...
2.052 Max Chamber OAL
2.918 Max OAL (Touching Lands)
My thoughts are to stretch my brass from firing it to around 2.045 and have my tim length to 2.035 instead of the book length of 2.005.
Also, I played with OAL of loaded ammo to be seated just off the lands by about 0.010-0.015 to allow for variances in Sierra MK projectiles which brings brings me to an OAL of 2.905.
I plan on loading this with my current recipe that has proved to perform very well from my rifle so far.. Hopefully, It will get better with the new seating depth.
Can someone here who loads .308 Winchester give me their opinions on these numbers and also give me some advice on loading specific ammo for my rifle? Thank You.
