Welcome tk 300,I'm a 300mag fan myself I'M sure we have all kinds stuff you would like to here,so come on in.
Just started load development on mine today. Barrel break in, & first fireing are as follows:
RL-17, /180Accubond .015 off lands/ Fed.215 primer,/Nosler brass, / Long Action Model 70 Win/Custom with 26" Hart 10 twist.
63gr barely sub moa 5 shot group
64gr-Barely sub moa 5 shot group
65gr- gun hated it. 1 1/4+moa 5 shot group
65.5gr- 3/4 moa 5 shit group__slight tension on bolt lift__
66gr (MAX LOAD) -3/4 moa 5 shot group__slightly more tension on bolt lift, but not stiff. No cratered primers, no shiny marks on brass etc.__ but it was time to throw in the Rowell. I was close. Sometimes you can just tell, ya know.
RL-19 is next, followed by H-4350Extreem for the 180's
And IMR-7828ssc for the 200gr Accubonds.
