375 zero distance

Frederik · Feb 2, 2020

There are a lot of factors to consider like stated above the 375 is really a good all rounder and if you know it can do some fancy longer shooting. But even with the correct zero and distance reading if your nor familiar with your rifle that is not going to help.
If you know you are going to an area where longer shots are required load a lighter bullet 260 or 270gr.
But play with your rifle and physically see what it does on the range not just what a ballistic app tells you.
The scope you want to put on might limit you expecially on longer ranges but on the other hand if it looks too far on that scope you know you are a long way off.

Agreed regarding ballistics apps/trajectory tables. I know a guy who zeros at 25 yards because his ballistics table tells him exactly where it’s gonna hit out to 300 yards. He misses sometimes.

If only it worked that way in the real world. Too many other factors involved to go with that plan.

Mine is 200 yard zero with 300 grain Accubonds. It ends up less than 2 inches high at 100. I'll add that I wouldn't take a shot much past 200 with my .375. Last animal I took with it was a cow elk at about 150 yards. She didn't take a step.

For what it's worth, I'm also doubtful I'd take a shot much past 275 yards even with my .300 Win Mag. That's about my limit.

Here is an interesting article by Chuck Hawks about Maximum Point Blank Range which is a concept fairly new to me. The idea is to keep the bullet in a +/- 3" path so a person can just aim right on without holdover and still hit vitals. For the 375 HH (300 sp at 2550), 2.8" at 100 yds will keep the bullet +/- 3" from zero out to 250 yds. Personally, I have mine zeroed at 100 and I'm happy with that.

Jack O'Connor advocated way back in the day sighting in two to three inches high at one hundred yards depending upon caliber to eliminate the need for holdover on most shots at reasonable hunting distances. There is very little new under sun.

Yes sir. I had an art professor once tell me, "Come up with a completely new pattern and we'll make millions!"

3" high at 100 for a 257 wby might be too much.
the bullet will keep going up and go too high before starting to come down again.

That's why old Jack said two - three inches depending on caliber seventy years ago.

Ran this on Kestrel with my load. 100 TTSX at 3670. 3" high at 100 yards, 3.3" high at 140 yards and than starts coming down. 2.80 high at 300 and dead on at 410 yards. I forgot too look where it would 3" low. 450?
I have mine 1.75 high at 100, dead on at 300 yards.

what we have now is things like jbm ballistic calculations for nothing.
you can plug in +/- whatever you want, and it will tell you how high to be at 100, how low at 350, and many other things at a glance.

I don't like to go over about 1 1/2" at 100. Much over that and you might shoot right over the back of smaller pg.

Rule 303 · Feb 8, 2020

The 375H&H with a 270 grain bullet is fairly much the same trajectory as a 30-06. In other words it has a very usable trajectory to 300mts. I have mine zeroed at 200mt, like most of my rifles. With a 300grian bullet it is still in the heart of a Red deer at 100mts and needs about 9" of hold over at 300mts.

When all said and done choose what ever zero you want then test at 25, 50, 75 and other major distances (say every 50 mts) out to 300mts. Know your rifle.

rule 303,
your post raises a good feature ot the 375 h&h.
with a 270 gn spitzer type bullet zeroed at 200 or a bit further, a 300 gn bullet will often be dead on at 100 for the same sight setting.
this can offer great versatility.

I like your thought, the target I posted on page one when I switched from zero at 100 yd to 200 yd I also switched from 300 gr to 270 gr

Do you think if I went back out and shot the 300 gr bullets my rifle would be zeroed at 100 yds with them?

MarkB · Feb 8, 2020

With every gun and caliber I have always sighted for maximum point blank range, including the 375 on all previous hunts. But now sighted in for dead center for this summer's safari. Want to know that bullet will go thru that small opening when lion presents if needed, and the small target on my croc makes me nervous. Both need a bullseye hit I think. Sight in should be dependant on hunt I believe.

Cant see any reason for a 400 yd shot with a 375, I prefer to hunt game. Cringe when I see the TV guys camped on a mnt top shooting PG across the valley with a truckload of sniper gear. Why? I think they are missing a huge part of safari. But that's just my feeling.

bhfs300,,
cannot comment on that cartridge, but would be worth a suck it and see.
then you will know 1 way or another.

A piece of advice for the novices reading this (which those of you posting are not).

There is no substitute for practice. A 100 yard zero or 2-3” high at 100 gives you an idea of where the bullet should be at 300. Real life can be quite different. Wind, body position, lack of calm, Altitude, and other factors can make that 1 MOA rifle much less accurate. If your home range ends at 100, find another place to shoot at greater distances. That practice will be eye opening.

and remember, "one group doth not an accurate rifle make".

I've enjoyed reading every response.
But as I suspected the bottom line is get out and shoot and see what works best for my intended load and application.
