Hunting Zero ? - Bassfish1952 - 01-08-2024
Many of my friends use 1" at 100yds and call it good and say Deer vitals are 8" circle so hit inside it you're good. At one time shooting a .270 or a 30-06 and most shots at 100yds or less I did too. Now the place I will be hunting offers shots out to 225 and a few out to my personal limit of 300 yds
I knew about MPBR but didn't give it much thought for hunting
Now shooting a 6mm. 103/90gr at around 2800-2950 My thoughts have changed bullet placement seems more important so I'm looking at a MPBR using a 3" circle and a cheat sheet from 230yds out to 300yds.
What do you guys use and or do you dial it in for each shot ?
Thanks

I haven't done enough with the 6arc to really have any meaningful real world experience, but I would suggest that you look at the Hornady ballistic calculator and start fudging your zero around a bit. Be sure to measure and set correctly the sight height. You may want to try to find a zero distance number that gets you approx +/- 3" MPBR from 0- 300. Then again you may want to try to stay flatter in the 100-200 range and hold up at 300.
The gas gun 556/223 does well with a 36yd zero. Some info on that out there on the web
Also I don't know that bullet placement is really any more or less important based on a shift down in caliber. I'll probably stick with my 260 bolt gun for deer, but if I do run either my 6arc or 223 AR's I'd want to be pitching Nosler Accubond bullets.

We'll see if this comes across with copy/paste. This is the 87 Vmax and a 50 yd near zero, but the 90 ELDX or 90 accubond should be very similar. The ELDX should be flatter yet.
Velocity is pretty quick as I have a 22" barrel.
