How far will the trajectory drop

wboggsHow far will the trajectory drop
How far will the trajectory drop on a 36 grain, lead round nose hollow point, 1280 FPS at the muzzle, 1010 FPS at 1,000 yards my question is how much drop at 300 yards? The box says it drops 1.8” at 100 yards sighted at 50 yards.
I haven’t even tried yet because I’m still collecting information but I’m determined to shoot a .22 rifle at 300 yards and respectfully hit a target.

Antelope Sniper109.9 inches at 300 yards
3267.2 inches low at 1000 yards. That's 90 yards, or 312 MOA. In addition every one mph of wind would push your bullet 4 feet.
It's kind of a tough shot, but if you did hit the target, with 12.6 FPE you might still punch a hole in the paper so long as it doesn't have a thick piece of card board behind it.

wboggsHoly crap...
So if I hit a 22" x 22" piece of paper I should celebrate?
I did purchase one of those calculaters for figuring this out.

Yea, kind of like this:

Antelope SniperHmmm, so how would I do it?
You would need a 30mm scoe with Maximum adjustment that about 70 MOA, and a 20 MOA sloped rail. Mil-dot or TMR reticle, on a Leupold MK 4 mil-dot scope its 6 mils to the dupled. With the scope on minimum power, that's and additional 72 MOA of holdover for a grand total of 162 MOA of holdover/adjustment under perfect conditions....that get you on targer (in theory) somewhere around 700 yards. At 1000 yards, you would still be 150 MOA low, so even with all that adjustment, you would still need to hold an additional 125 feet above your target. So you would also need a shear dusty cliff face behind your target, and a really good spotter with some excellent glass.
If you pull it off, be sure and post it to youtube for us!

wboggsAntelope Sniper you are a downer man!!!! I'm determined but I doubt I'll have a video of the first hit. Amazing as you're making this attempt to be, if I do hit it, I will video it another time. Pictures of the first target though and I'll be honest.

Antelope SniperSorry man, not trying to be a downer just trying to set you up for success. 1000 yards is a long ways, and I can tell you it's hard even with a real gun. I've hit target with a .22 out to 300 yards, but after that the physics become alot more difficult. There is a 12 foot difference in impacts just between 300 and 400 yards.
Start at 100 yards, and work your way out, see what you can do. Even if you are only able to hit the target at half that distance, it will still be an impressive shot worth of youtube.

wboggsI was just kidding…
I agree and I’ll be damn proud to hit the paper and I’m going to try it; I’m always up for a challenge.
I recently joined a second gun club and they have a 300 yard Range so I have to; it’s calling me. Problem is I go from 50 to 100 then right out to 300 yards; that’s why I need this information. Maybe I’ll get a stick of some sort to measure out the sight picture to overcome gravity.
This leaves me with a question though; why does the box say the ammunition has a mile range? That must be in outer space or something; or just lawyers.
31 July 2010, 05:08
Antelope SniperWell, if you pointed the rifle up 30 degrees and pulled the trigger, the bullet would travel 17.7 seconds before impacting the ground 1687.7 yards away with 4.9 ft lbs of energy. So the bullet won't actually make it the full mile at sea level, but pretty close. In the end you are correct thinking it is mostly for the lawyers, and a nice way to remind everyone they should always use a good backstop, even with the .22 LR.

wboggsAre you an actual trained sniper? You sure know your balistics.
31 July 2010, 06:57
Antelope SniperAlthough I severed in the military, I an not a trained sniper. I was awarded the name after I killed an antelope at 1000 yards (an no it wasn't with a .22 LR). Where I grew up there was alot of open country. The really big bucks know it, and would hang out in placed that required long shots. I come from a family of bench rest shooters, but on all the long distance stuff I'm self taught. Alot of reading, alot of gunpowder, and now I share what I can with others. Distance hunting is a great sport. Once you learn it, it will totally change the way you see the land and the way you hunt.

wboggsInteresting...I'm not a hunter but I like making difficult target shots.

Antelope SniperHuntings not for everyone, but I'm glad you enjoy our shooting sports.

wboggsHey Antelope, one more question.
I just watched a TV program about sniping and a guy shot a 700 yard (aprox) shot and had to take into consideration the effect of the spin of the bullet and aim high and to the left; is this something I will have to deal with, with my 300 yard .22 shot?
Bore specks 1:16" RH twist which would mean I shoot high and to the left; correct?
Didn’t make the shot yet; it's been too hot and if it's cooler, it was windy.
16 August 2010, 01:26
Antelope SniperWhat you are refering to is called spin drift. In a right hand twist barrel, it will cause your bullet to drift to the right. Spin drift is difficult to calculate. May ballistics programs will not include it, so the most practical way to figure it out to go shooting. I have certain rifles that I zero 1/2" to the right at 100 yards, which fully allows for the spin drift at 500 yards.
Zero for left to right at 25 yards, then see if you can tell the difference at 100 yards. If you can, you can use the info to guestimate what the sping drift may be at 300 yards. If I had to guess, I'd say maybe 2 inches at 300 yards, but on that, I could be totally off.

Well Hell if I'm within 2" we're going to have that party, remember?
Thanks for the info, I'll keep you posted after the shoot.

YEP!!!
Let me know when you make it to the range!

wboggsWell I think I’ve done about as well as I’m going to do at this 300 yard endeavor. Yesterday was a very nice day with little wind. I started at 100 yards with the Ruger 10/22, then 200 yards both wend well, then 300 yards. I used Aguila, Match Rifle, 40 grain .22 long rifle ammunition which I hear is one of the top performers. I hung a 22” square target backed by an 80” ish by 65” ish piece of cardboard and with a cross breeze that wasn’t moving leaves I got 5 out of 10 shots within a foot if the 22” square target. I didn’t sight for the 300 yard shot as I thought that would be foolish with how far the drop in trajectory was so I scientifically guessed. It was a full day planned at the range firing several guns in several situations so the packing for the trip was nothing short of a week’s vacation so naturally I forgot my camera in trade for all the guns and targets I suppose so believe me or not, I have no reason to tell a tale.
I am satisfied enough to put this challenge to bed, though I wish I was saying even just 3 of 10 within the 22” target, half the shots within a foot of the square is close enough for a 300 yard .22 LR shot for me. Since a 1 mile an hour cross wind will put me 4 feet off center shooting with a breeze I had to compensate for, hitting that close…I suppose the only thing I could do better is either hope for no wind at all which is all but impossible or fire the shot in a vacuum. There was one hole in the target that didn’t fit the 30 caliber bullets my buddy was shooting at the same target but it’s would be a stretch to call it a .22 bullet hole so I’m not taking that one as a hit though nothing else could have done that but maybe a ricochet from the ground in front of the target since all my hits were low.
Taaaaa Daaaaaaa……LOL

Congratulations Boggs. Nice shooting. Going from 200 to 300 yards is a big jump with a .22 lr. Just be careful, if you catch the long range bug it can be expensive!

Oh believe me, I started down that road about the time I started contemplating the .22 300 yard challenge and started looking at Savage, bull barreled varmint .223’s and the ultimate for this the 22/250 cannon and scopes with monstrous price tags but looked back at the last few months of purchasing 5 guns and the cost of all the nit picking equipment to pamper long distance brass, dies and all the other “must have” man stuff and quickly realized that when I had a job this wouldn’t be a big deal but on Social Security this is huge. So I put that one to bed and went back to splitting cards and driving nails with a .45 ACP and steel targets with the Ruger .357. I would drive myself nuts and bankrupt chasing single whole groups at 300 yards since that’s the only thing I see as success for me; I’m a compulsive shooting perfectionist. A man has to know when to quit and I’m learning. It was fun though.
