Re: 338 Lapua Mag loads? Reloder33? 250g Berger?300g SMK
I tried RL-33 in a 26" barrel with the 300 SMK and did not notice any significant increase in MV over Retumbo. I'm certain a longer barrel will.
Read thru this thread for RL-33 data and trend regarding seating depth if you have not already done so.
