I’d have to check but I’m pretty sure I’m shooting 32gr Vmax with that exact charge. Bugholes.18.5 gr 4198.
varmintshooter posted this load a few years ago and it turned out to be my best load with the 39's. Easily shoots in the 2's and 3's.I think 18.6 H4198 w/ 32's but with an 11 twist you might want to try 39 or 40 grainers with 17.8 gr H4198. They will do a little better in the wind.
