Apparently my .17 Mach 4 doesn't like HDY .17 cal, 25 gr V-Max bullets! I have tried loading them with W-748, H335 & H4198 powders with H335 having the best group (1.5"@ 200yd). This rifle with 25 gr Berger or Starke bullets in front of W-748 powder shoots groups @ 200 yds that can be covered with a dime!! I have RL-7, BL-C2, IMR 8208 BTX, and Varget powders that I haven't tried and I DO NOT HAVE IMR 4198, H322, Vv130 or AA2400 as I am out and they are unavailable. I'm using a seating of 1.770" and Rem 7.5 and Fed 205M primers.
Before I continue to burn up more powder and waste more primers maybe one of you can suggest a fix, as I believe these bullets will perform with the right combo. Thanks in advance.
