Soda Cans 700 Yds-Pepsi Challenge Record

[rsterne]

Using the JBM Ballistics Calculator, and using a BC of 0.15 and 1000 fps, scope at bore height, and sighted in at 700 yards shows the bullet 20.4" above the line of sight at 10 yards, which is 195 MOA (just 3.25* elevation for the boreline), which is the maximum angle.... The bullet rises 443.5" above the line of sight at 370-380 yards downrange, which works out to 37 ft....

That's not as bad as I expected.  Now I'm wondering what the record for an AG is?

[rsterne]

ChairGun has a Widget that calculates maximum range.... Using that same BC of 0.15 and an MV of 1000 fps, it says the maximum range is 2264 yards when fired at 34* Elevation, and it would reach an altitude of about 1900' at the apex.... The flight time would be about 21.5 sec, and it would have a terminal velocity of about 310 fps.... If fired straight up, it would reach an altitude of about 4700'.... about 35 seconds flight time, and the only a fractionally higher terminal velocity....

thanks but I must be having a SENIOR MOMENT, as I can't comprehend this part of your statement above-- ""Well Sir, You have a bit track left there"

Sorry if You understand my comment wrong...As You see my native language is not English so let me try again: I meant to say that You are using shooting  range which goes to 1000 yards and I think You will shoot that .257 from 1000 Yard to ram or cola can some day. I truly hope so

rintafile.........You're English is fine........I just didn't quite understand what you meant by those few words....Understand now and thanks for clearing it up so i could..I know the bullet will go the 1000 yds but not sure if i could hit anything smaller than a bus, but will go as far as equipment will let me.....Thanks for the good wishes..............Carl

[rifle50]

700 yds!?!?!  That is crazy far!  I don't think I could even see the cans at 24X on my scope.  That is just awesome.  And thanks for leaving the ranging shots in the video and not editing them out.

I dub thee "Soda Sniper"!

So now 2 liter bottles at 1,400 yards right? 

Thank You and You're  welcome.......I can see cans at the 8x but when i have elevation dialed i use 10-12 power....No 1400 yds, unless apt buildings are target     Thanks for the comments...........Carl

[rifle50]

Never mind.  I don't feel right raining on your parade.  Go for it, bro.

Thank You, MicErs..............Very nice of you to ammend the post and i will do likewise..........Carl

Truth is what made me do that is that I was thinking about what kinds of shooting was done at a 1000 yards in the Black Powder days.  It then flashed through my feeble mind that you are shooting at the same velocities, give or take a smidge, with better boolits, so...

It would be interesting to know your maximum ordinate on that flight path.

=)

Looks as if BOB gives a great answer here..........Thanks............Carl

I would like to know AG Record TOO??  The guys from Europe and here too i see most only interested in HOW MANY FPE can be generated? No one seems to be interested in EXTREME RANGE ACCURACY!  RoachCreek claimed Soda Can shot of 615 yds and claimed longest AG SHOT....I in 9 months of researching RANGE have found what i put forth here...........BLUETHUNDER on this forum claims on a 45x45 in target hit 8 of 10 shots at 700 yds with .308 caliber i believe. I have shot several times at 700 yds on RAM and the current post of Soda Cans.....I claim that as a RECORD FOR AG?? No other data seems to be public?  I have also shot 3 times at 800 yds with 3 different bullets and weights, on a RAM....Haven't posted on that yet and was a BIG JUMP from 700 yds believe me.....Since nothing is available on YOUTUBE disputing this I claim that record, in my mind anyway and probably the first to even try it.....One has to have a place to even do it and i mean a dirt backstop that will show where you are even hitting as the strikes are getting WEAK for dust kick up........I am doing this strictly for fun and holds interest for me..........Once i get to the limit of being able to hit something i will be off to another project and will have lost interest......May go back to F-Class again as have taken this year off for AG tests....

Carl

[rintafile]

on my mind..Nothing to do big FPE if You can't hit anything above 25 yards.. Accuracy and range is something which I'm interested and same  I can say few of my friends also...

Excellent shooting Carl. Just wondering how do you get to the cans or targets to reset them at 700 yds?

Excellent shooting Carl. Just wondering how do you get to the cans or targets to reset them at 700 yds?

Thanks.........It is a regulation 1000 yd range with 24 shooting positions on the berms and target frames in pits. There is a road along each side.....I DRIVE DOWN AND BACK  to place targets and pick up an place camera etc...........During the week I am USUALLY only one there with maybe someone at the pistol range...BUT ONLY person on the 1000 yd range...It is perfect for what i am doing.......F-class and High Power shoot there monthly on a weekend and until this year I have been only air. I am a member there and it is limited to i believe 300 members and locked gates with member having combination, and no one to supervise.....Weekends they have matches......  That is why i drive 70 mi each way to get there when a 220 yd range is 20 min from home.  Thanks for comment..........

Now that is a sentiment I understand.  Then one day you will be getting  bored with your current "thing" and you'll ask yourself, "Did I really max out my range with that AG?" and you will be back to the races.  =)

BOB, I downloaded the CharGun........Not sure if i believe it at LONG RANGE??  As you well know that as the bullet slows down drastic B.C. changes degrading very fast........I did some BC testing over 2 chrono/s at 50 yds.......Took that number and entered particulars into HORNADY BALLISTIC TABLES.....Printed to 900 yds. at 50 yd increments.......Took the speed at 100 yds projected and entered into the JBM BC CALCULATOR as the Hornady used calculations as speed for NEAR, and 100 yd speed from HORNADY just to see and the BC went to like .07 or not good........I used the 300 yd figure and BC was of the chart all most.......YEt i can get to 800 yds so far so i can't believe the numbers........But i am one as you know who believes the DOWN RANGE facts    .................Carl

BC means very little if your bullet doesn't match the model used for the BC.... If you are using the G1 Model, and the bullet is a lot different in shape (which it is), then the calculations won't be perfect.... ChairGun has several models built in, I used the G1, and a BC of 0.15 for the examples I gave.... I don't know what the Hornady uses for their model, but the JBM uses the G1 as the default, but also has several built in....

I'm not sure what you mean about the BC degrades as the bullet slows down.... The drag actually will be near minimum at about 600 fps for most bullets....

Bob, I use the G1 in ChairGun and Hornady gives a choice...I use G1 there except for my BERGER MATCH bullets and they give the BC in G1 and G7 which I use for the Powder Matches.........I meant that the BC is different from your average speed. Speed up, more psi and it gets better. Slow down lower psi, and bullet speed, and it gets LOWER, the BC..... You mentioned that in a  response to one of my posts.  SO I ASSUMED, probably wrongly,  that as bullet was way slower down range, BC must have changed?  And with my sample test numbers above......Used the bc i actually got at 50 yds, plugged bullet speed, weight, BC @ G1 and temp, humidity into HORNADY and used that initial speed as the NEAR SPEED in the JBM BC calculator and added from HORNADY printout as if i had a chrono at differing longer ranges and the numbers for BC were basically like a pellet???

Carl

The G1 model already takes into account how the drag changes downrange, all the models do that.... It's how good your bullet matches the model that governs how accurate the numbers are.... I'm afraid I don't understand if your results at 700+ yards are better or worse than what the calculators are predicting.... but whatever you are getting in reality is the correct answer for YOUR bullet and velocity....

Thanks BOB, I didn't know that.........Good info..................Carl

Carl, I'm moving that direction, rifle version only.  Kicking and screaming of course
