If you have only iron sights I would personally sight in for 100 yds, as the Lott has 250 yard capability in a pinch. If the sights are for backup or close and dirty then 50 yards or possibly 25. Good shoot’n.

None of the above...1" high at 50 yds...

Dead on at 100 yards would be good and I wouldn't be surprised to find that it turns out to be 1 inch high at fifty.
Take care,
Dave

Yep, seems like we have been over this before. Marakai posted a ballistic chart/graph.

As Ray and Dave say, 1" high at 50 yards, and that will be very close to dead on at about 20 yards and 125 yards.

So I voted for 100 yards, which would be about 1/2" high at 50 yards, and dead on at 25 yards and 100 yards. You are basically shooting a trajectory in the ball park of a .22 mag rimfire to .22 Hornet, and you have two intersection points of the bullet's parabola as it rises through the line of sight (25 yards) and then falls back down through it (100 yards), assuming 1" iron sight height above center of bore, velocity = 2250 fps, and BC = 0.3, roughly speaking.

Thank you all,

I'm a bit hesitant on any of the advice Ray gives, as it may be for converted wheel locks and black powder. But with others in agreement, it must be for a modern weapon and smokeless.

Ray is it true that you edited the reloaders guide to slings and atl's?

Seriously though, I tried to find the trajectory chart that RIP mentioned, but nothing comes up in the search.

RIP could you please point me in the right direction? I'm going to have to try some 150-250 yard shots, maybe I can use this on close whistle pigs.

Thanks again guys, you're the best!

What Dave said...
you'll find midrange trajectory is about 1 inch..

or you can use a 2" bull, use a 6 o'clock hold, and zero

you'll find these are functionally the same thing to about 200 yards...

and your sights should be regulated for this



RIP, aint a lott is more in the hot loaded 22 hornet class, right?

I don't know I like all my big game rifles to be 2"high at 100 yards and it usually means zero at 200 yards. Also dead on at 25 yards means 2" high at 100 yards in many instances.

Mine's set for dead-on at 50. That's all I'd use the open sights for-- and only then after scope failure. If you don't use a scope I would sight it in for longer range.

Jeffe,
Ja, closer to a .22 Hornet.

PC,
You would be talking about flatter shooting rifles with .30-06-like trajectories.

Minkman,
I can't find it either, but use AccuLoad or some other software or good ballistic table and you won't have to depend on a bunch of imprecise baboons such as us.

Here is a list of trajectory points for 500 grain RNSP at 2250 fps MV by 25 yard increment out to 325 yards for whistle pig with iron sights 1.0 inch above center bore line:

0 yds: -1.0"
25 yds: 0.0"
50 yds: +0.5"
75 yds: +0.5"
100 yds: 0.0"
125 yds: -1.1"
150 yds: -2.7"
175 yds: -5.0"
200 yds: -8.0"
225 yds: -11.7"
250 yds: -16.1"
275 yds: -21.5"
300 yds: -27.7"
325 yds: -34.9"

If I used a scope with 1.75" visual axis above boreline, same load, I would have (to the nearest 0.1"):

0 yds: -1.8"
25 yds: +0.1"
50 yds: +1.6"
75 yds: +2.5"
100 yds: +3.0"
125 yds: +2.8"
150 yds: +2.1"
175 yds: +0.7"
200 yds: -1.3"
225 yds: -4.1"
250 yds: -7.6"
275 yds: -12.0"
300 yds: -17.4"
325 yds: -23.6"
