25-06 help

Normal practice is to sight in so you are 3" high at 100 yards. This will let you get out close to 250-300 yards holding dead on. Your bullet won't be more than 3.5" or so high, or the same low.

As others have pointed out, your numbers defy the laws of physics. Bullets only drop from the instant they leave the muzzle. I suspect you are having some accuracy problems. Did you base this on one shot at each distance? Better to shoot 3 shot groups and at least a couple of them at each distance before deciding on where the point of impact is.
 
I've been doing research for a friends 25-06, highest BC bullet is the Speer 120gr. BTSP. Push it with Retumbo or RL25. The 100gr. Speer BTSP will shoot flatter, but drift more in wind. This is out to 500 yds as ran on my Quicktarget program using possible FPS with each bullet.

i do believe the berger 115 grain bullet has a much higher bc then the speer120btsp.

You can get lots of free load data, including manual downloads from bullet and powder manufacturers' web sites.

Not sure why you are zeroed at 100, low at 200 and 12" high at 300.

Yeah it's possible but his accounts are little akward ......

it's done on regular bases and tested in two different times and two different ranges (300 yards range including silverdale and brockville) with 270WSM in my sako and used on all my hunting trips as primary hunting gun with my reloaded loads , although can't tell anything bout 25-06 don't have one

It shoots exactly +1.5 inch @100yards, +2.5 inch @200yard and +8.0 inch high at 300 yards - Biggs
 
I don't know if it has been mentioned but this could be caused by changing magnifications when shooting. For example you put it at 4X at 100M and dial up to 9X for the 300M shots.

I have had two scopes do that. They seem fine hold their zero, and track well but for some reason shot strange. My theory was confirmed with a bore sighter. The POI changed as the power ring was turned.
 
Dose it not matter that I shot 117 grn at 100 and 200 yrds and 100 grns at 300 yards with the gun zeroed at 100 yrds shooting 117 grn bullets ? I think that was my problem. Please correct me if I"m wrong.

Could very well be. The 100gr bullet may have been a lot faster than the 117 and therefore could have shot higher.

Only way to sort things out is to shoot one type of load at all ranges. This will eliminate a key variable ( bullet speed). I hunted with a fellow years back that carried a mismash of .308 shells hunting all the time. As long as deer were under 150 yrds he would connect but he never understood why the farther shots always eluded him. I go him settled with one load that worked well in his gun and nagged him like an old fish wife about sticking to it when we hunted. Problems solved.
 
A different load will typically shoot to a different point of impact, regardless of velocity differences.

That would be the obvious explanation to the difference between the 100/200 yard trajectory and the 300 yard POI.

Thanks someone actually read the posts
 
Actually Gaddye the mixed or mislabled ammunition is dangerous. To the animal on the receiving end. That ammunition is the difference between a quick death and a slow lingering death or a cripple for the rest of it's life.

If it is as you say factory ammunition, people should know and be aware.

bearhunter , OK I understand your point, however I will not say the manufacturer or the seller are responsible as I don't need a lawsuit. Today I have no knowledge of who or where the ammo got boxed wrong but will try and sort it out tomorrow with the dealer.
I think this is the only rational decision that can be made and will up date when I get home tomorrow.

Or you can PM me for the info and be responsible for it yourself.

Your solution is good. I've seen different weight bullets than indicated in factory fresh boxes before but never mixed weights. That is unusual.

You say your group was 12 inches high at 300 yards. There is something else wrong there as well. Factory 100 grain flat base spire points at 3230 fps, which is a median factory loading, will shoot 10 inches low when the scope is zeroed at 100 yards. The 117 grain bullet loaded to 2990 from the factory and zeroed at 100 yards will shoot 12 inches low at 300 yards.

This comes out of the Hornady tables and the velocities are pretty much median standard for factory loads. The only difference might be if the lighter bullets are some of the "light magnum" loads. Even then, your results are off the scale.

I went out today to sight in my coyote rifles, a 6.5x55 and a 25-06. Both are Tikka T3s'. Just for my own concerns, I loaded up 20 rounds of 100 grain bullets to shoot appx 3200 fps and 20 rounds of 117 grain bullets to appx 3000 fps. The day here was nice and warm for this time of year, 10C. My targets at 300 yards, with a 100 yard zero were almost exactly as the Hornady drop chart suggested.

100 grain spire point flat base - 2 1/2 inch group - 11 inches low.

117 grain flat base round nose - 3 inch group - 13 inches low.

The ballistics on the heavier 25 cal bullets are pretty good. They are very efficient bullets.

There is something else awry here.
 
bearhunter , the ammo was 2 different loads in 2 different boxes but the boxes were labeled the same.

There was a recall on the ammo and all but 2 boxes got returned, one of those boxes is mine.

The two bullets have different POI's. That is the reason.

I still want to know who's ammo. I would like to check out the recall and find out what happened.

Please, identify the ammunition you found to be mis-labelled.
 
Jordan Smith, if you read the post you quoted, the two bullets I used in the test were of different weights. The exact same weights the OP had in his boxes and loaded to the same specs.

There is no way there should have been that much difference in POI. The lighter bullet, at 300 yards shouldn't have printed 12 inches high period. It should have printed 11 inches low. 23 inches from where it should have printed, is reason for concern. Unless the ammunition was loaded extremely hot as well, which would have shown up on the case, maybe with catastrophic results, there is most definitely another problem. I doubt bullet weight has anything to do with it.
