View Full Version : sighting in

Hey Guys!

I have two questions

When you sight in a rifle (using a scope of course) for long range shooting
do you zero at 100 yds or further.

Would 40mm obj lens be good enough for long range shooting, or should i go with 50mm.

Thanks in advance

I zero most of my hunting rifles at 200 yards. I do load development for both my competition and hunting rifles at 200 yards then dial up for whatever range I am shooting, be it 300, 600 or 1000yds then they get left wherever they were adjusted to at the last competition. If I shoot a different yardage at the next competition I adjust then. I use 6x24x42mm on my competition guns and 4x16x42mm on most of my hunting guns. I do believe a 50 or 56mm objective would be better though , I would prefer a little more magnification and have my eye on the Sightron 8x32x56LR scope, I however am a tightwad.:D

Most of my friends and I set up our rifles for a 1000 YD zero. Using Burris Signature rings, usually the "Z" style, we mount them to be XX inches high at 100 yards, usually in the mid 20" range. The actual distance "high" at 100 yards is dictated by an exterior ballistics program. Using a 20-25 moa base and swapping ring inserts, we try to do this when the vertical adjustment of the scope is in the middle of it's adjustments. That also allows you the most windage adjustment available with the scope. Works good for us.
With the Leupold and NF target scopes, this usually means that you can't actually get point of impact to point of aim at 100 yards. No problem, put a target low on the board and the groups will be a couple feet high.

The only thing a bigger objective will get you is more light. I would use a 30mm tube vs. a 1 inch tube. The bigger tube gives you more adjustment for elevation/wind.

I zero all of my guns (both BR and hunting) at 300. For big game, it's baisicly point and shoot out to about 350 yds. That is when (on my guns) the bullet is 4" low and dropping. This is when you start to need to start to use holdover/dial up. I am never more than 4" high either. Most computer programs will figure the max point blank range for you if you feed it all the info it needs.

It's just a habit of mine from the pre-BR days of LR hunting. I just carried it over to the BR game. I always dial back down after a match, and start over from there.
