i have my gun sighted in for 350 yards. how much tougher is it really to shoot 150 more to 500 yards in good conditions. hitting 2.5 inch bull every time at 350. ???????? how much harder will it be. savage model 12 f/tr chambered in 7mm rem. mag.
350 to 500 yards
- Thread starter model 12 toby
- Start date
No one is going to be able to tell you much without the wieght of the bullet, BC and MV.
3000 feet per second, 162 grain, .625 ballistic coefficient
im not even looking for specifics really just how much tougher is it? under normal circumstances am my going to be able to hit a 10 inch plate over and over again by just adjusting my scope?

Short answer is yes.
If you are shooting a MOA or less at 100 then 500 with a 7 mag shouldn't really be an issue. It will take some trigger time on your part.

got gun sighted in very well for 350 yards. 2.5 inch bull almost every time. what would that equate to at 500? want to go hunting out west some day hopefully. is it going to be tough to hit vitals on an antelope?

I thought much the same.
When I try/tried 500, I noted much greater influences on the rifles/cartridge's external ballistics due to weather ( WX ).
A 20-30*F warm-up over the course of a one-day shoot, had tremendous impact on the bullet's flight.
"Come-ups", or even MORE important... forgetting to make necessary scope adjustments to comp for WX effects
were/are significant impacting factors in one's precision shooting success..
"Cold-bore" shots taken at a shoot where no fouling shots are offered; are problematic.
500yd egg shoots are a great example of what mischief might befall the typical shooter; and you will see the full panoply
"brain farts" played out there.
These are only some factors that have influenced the popularity of propellents; such as Hodgdon's " Extreme " line of powders.
Best of luck in your endeavors.

you have some good advice - my 2cent worth - if you are hitting a 350 objective as stated, the loads are capable of 500 yd reasonable accurcy - plenty of energy left for kill
the problem is wind /mirage effect at the additional distance are greater per yard than the first 350, the bullet is slowing
thus you need to use all your skills to getthe results you want, this means the objective of a clean kill are upto you and your skill

Redneck math....
Double your group size and double the distance, is 5" at 700 yards. Highly unlikely on a consistant basis.
You're averaging just under 3/4" at 100 yards, which equates to under 3 3/4" at 500. Also highly unlikely in a hunting environment, unless you can tote your bench. Keeping your groups under twice that at 500 would be an acomplishment.

lets modify it / an say your 2.5" @ 350 ~500yrds would equate to 3.75" [.75 X 5]

your drop is related to speed ...... 3000fps at muzzle so U say.

I think what your asking is for accuracy related to how well your gun shoots at 350. When i work loads up for my rifles that i build for 600 yds. at 300yds . i want them to be less than 1" with me shooting not that this is the best they will do .it is the best i can do consistantly. Achieving that i know
i can shoot anywhere from 1.500" to 3.000" groups . With a good shooter behind the trigger the lower end is well within reach . at 2.5 inches at 350 may work out to just under 6.500" . but you won't know for sure till you try . The Rifler

sounds like it could be bout a 50% chance of hitting at 500 on a consistent basis on a ground hog??????? just need to give my scope an adjustment and give her a whirl. shot one today. couldn't get a good shot from very far though. i was all over the hill side. was another hill beyond that but didn't walk to it. ground hog was probably wondering what the hell was zig zagging all over the hill side. got to 296. wasn't too hard a shot. made quite the mess.

No business trying a shot on a live animal that you are not 100% sure you can make, I don't care how accurate the rifle is!
My $0.02
My $0.02
should get it sighted in for 500 first then huh?
500 yards is a fur piece downrange containing many variables. 600 yards adds to the ludicrisness of so-called HUNTING range. Stick to your 350 yard proficency. I'm still stuck at 300 yards accuracywise. Doesn't matter what bullet or velocity, so much as windage varibles and gravity control. Once a bullet enters this envelope of varibles, ambient temperature, altitude, preciseness of powder charge all enter the picture. A paper target does not care where it is hit, yet an animal will care. Be a true sportsman, and learn how to stalk. Cliffy

You need to practice at 500 yards under field conditions! If you can make the shot 100% of the time from a cold bore, then you're ready.
you're not providing very much information on your ability or equipment,like "rangefinder"? and yes,"field conditions"
Shooting a factory rifle at 500yds is much harder than shooting 350yds.The bullet is really just starting to drop @325yds and being 6.3" high at 200yds and 19" low at 500 is a pretty big margin for error on a 10" standing(if you're lucky) groundhog if you dont have a good rangefinder thats for sure! there is a pretty slim chance of making consistent hits without knowing the range?
Dialing your turrets(dope) that have been proven to hit on ranges to 500yds are a must and knowing the range will put you on the right track.
0-300yds isn't really that hard
300-500 is where you learn to take the next huge leap to
500-800yds then its that much harder to go to 1K in my opinion.
with a 100yd zero you will have 3' of drop minus wind.Practice setting up clay pigeons randomly out to 500yds and see how you do,and by all means,let us know.My bet is you will come back and say,"I missed alot" they are @4.5" tgt and what you will need for a groundhog.

Sounds like you have some serious work to do.
You definitely need some trigger time.
Your biggest issue is you need to do a drop chart.
Take some time and work up a good load for your rifle then do a drop chart. Shoot at different ranges and record the results so you know where the impact will be. After you get your chart done you can cross it over to a program or use something like JBM calcs http://www.jbmballistics.com/cgi-bin/jbmtraj-5.0.cgi
don't spend a bunch of time on the bench once you have the load worked up and the drop chart done.
Get out and shoot off a bipod or however you hunt. Lots of practice and those 500 yard shots will be much easier.

clay pigeons? excellent idea. wont have to retrieve them. one walk out. no walk back. i could put several out. get out the range finder and get to work at all ranges. might give up ground hog hunting and switch to that. ;D
thanks everyone for all the advice. i got a lot of work today if i could ever just find the time.

Awesome,you do have a rangefinder.Have you gone to JBM Calculations link that was posted above to learn how to use that? If you need help,please ask,I would recomend using the bullet pulldown at the top and looking for the exact bullet you use in "Litz" using a 100(i personally use) or 200yd zero.It should match pretty close to the actual drop of your bullet,you may need to tweek scope height or velocity a little bit for it to match your "actual" drop.A bi-pod or a bench(when the grass and corn grows) will help.
glad you like the clay tgt idea,they are cheap and the farmer won't mind at all as opposed to smashing cans or bottles in their field
They also make a great drinking cup for my hunting partner and Groundhog finder,Bear (my black lab).When you start hitting them that far away,they become hard to find,as also stated above,they are often found over the next rolling hill.You think you are in te right spot,but you're not.
