Hey, welcome to the forum!
I'm running Nosler brass, Fed 215 primers and 78gr's of RE25 in my Rem 700 SenederoII based custom rifle
with 28" barrel.
My rifle is a tweaked Rem 700 SenderoII with PT&G S/S bottom metal, match barrel mated to a pinned Tubb recoil lug, Jewel trigger and original HS stock re-worked and bedded by myself. The action has been blueprinted and trued, and I have also fitted a PT&G spiral ground bolt and shroud.
