newbie and others...where did you end up settling with H4895 and the 108s? I have some loaded up to try tomorrow...starting at 30.1 and working up to 30.8. I didn't even try to go higher than that at this point based on the experiences you posted. I also plan to try some Varget too.
For the 108s - I settled on 30.8gr H4895 for my setup (2938fps). Your setup might be different. I didn't do any further load development with the 108s because I received my order of VT 103s.
