RL 17 and 150 TTSX. Accidentally primed some brass with 215 instead of 210's and decided to try RL 17 with this bullet as I had only so so luck with H4350. 55 and 57 gr loads six shot went into 3/4 inch, 59 opened up and 60 gr went right back into 1/2 inch. Rather be lucky than good any old day. Rifle is pre 64 fwt in mickey w/ 6X42 Leo.
Any others using RL 17 with 150,s?
