Elm fork 100yd range question

I'm planning on going soon to shoot my new 30-06 and had a question. Has anyone taken their .22LR on the 100yd range with a centerfire rifle to plink with while the rifle is cooling off? Also, I know they have a 3x scope minimum, and the .30-06 has a 3-9, but the .22 has a 2-7 and was curious if they would care.

I've only gone for pistol, so I'm in the dark here.

:tiphat:

According to the last time I was there (http://texaschlforum.com/viewtopic.php?f=10&t=57024), .22LR is only allowed on the 50yrd range.

The scope won't be a problem, but they might restrict the .22 to one of the 50 yard lanes over on the left side (facing down range) of the firing line.

Thanks all! I guess I'll have to take the .30-06 to the 50yd range, which probably isn't a terrible idea since I'm not particularly experienced with centerfire rifles.

It looks like you have to start on the 25yd range to sight it in before you can go to a 50yd. Interesting....

Hi all, new to the forum. If you bring your rifle to the range officer at the 100 yrd range, he'll actually bore sight it for you for free. While I'm not a big fan of how they charge you up there(separate charges for pistol bay, rifle, tac bay, etc.), their range officers are very friendly and helpful.

A lot of the issues they have at Elm Fork isn't just their policies.....it is what is on the other side of the range. The Golf course is somewhat of a problem for them if a bullet wanders towards anyone hitting the little while balls. Hey at least under new ownership they got rid of the tubes you used to have to shoot through...I hate those things. Move a scoped rifle a hair and you get a close up of a bug!

I guess instead of yelling "fore", you yell "45".

I've only been there once, but I don't recall a golf course in the area. Maybe I came in from the wrong direction. How far downrange is it?

I don't question that anything Andy says is anything other than an absolute fact. I don't get the trajectory of .22rf at 100 as being the culprit.

My previous understanding for .22 rf was that, from a rifle, if the point of impacr was one inch lower than point of aim at 16 yards, its trajectory would again, be one inch low at 60 yds. Thats pretty much 1" point blank range from 16 to 60.

If true, it'd be kinda hard to grasp the rainbow trajectory as the reason why .22rfs aren't allowed on the 100 yard range. There may very well be sound reasons for the exclustion. It don't seem likely that trajectory is one of them.

What am I missing?

Thanks,

salty

I don't know anything about the size/angle of Elm Fork's range, here are the likely trajectory ranges they are dealing with:

40 grain bullet going 1260 fps (high velocity) - variation of 5.25 inches over 100 yards:

Subsonic load - variation of 7.5 inches over 100 yards:

If this is true (and I don't doubt that it is), why can I go to GPSR and nail bulls-eyes all day long with my Marlin 60 and NOT have to point the barrel way up in the sky (exaggeration, I know)? FYI, I typically use Armscor subsonic loads.

Have you tried shooting it at a bunch of different ranges to see where it is hitting all along it's trajectory? It's just math/physics. There are plenty of ballistics calculators on the web for you to calculate exactly where the bullet is at any distance.

I suggest you plug in your numbers to one of the many online calculators (JBM has several good ones) and then try shooting a round at every 5 yards, then see if the two don't match.
