I have been lurking for a few months soaking up everyone's insight, and decided to build a 23" Lilja Grendel with 4-16 Vortex FFP. Its a great set-up getting hole on top of hole pretty consistently @ 100yds with Hornaday Factory 123 SST/AMAX. I just ran my first ladders with CFE223 & ARCOMP and I am somewhat surprised that ARCOMP ran much tighter groups & so much slower the CFE. I see a lot of people getting good groups with CFE. Data below (sorry for the overload). My question is this, given the lower velocity and the intention of reaching out to 1,000yd+ at some point, should I continue to work with CFE and try to dial in groups or stick with ARCOMP at lower velocity. Thoughts, opinions?
