I've been shooting the 105 Amax from a factory SPS 700 at 1750ft from 25-80 deg. I'm now over book by .5 grns w H1000. Shooting really well now. I'd say I just got them spinning fast enough to stabilize.....but JBs last article says the "ragged edge" on fps isn't going to make or break the combo. And he just posted right above me.
Anyhow the 105 Amax and 105 BTHP are working at 1700ft in a factory SPS Varmint.
