Remington titanium 7mm-08

[hunter89]

So i bought this gun last year and didnt have time to really play around with it till now.The old owner said it shoots 139 gr hornady soft pionts with 42.2 gr of Varget.I loaded a bunch of these up and can cover 3 shot groups with a quarter.So all is great and i sight it in 2 1/2 inches high at 100yards.I then set up a target at 200 and my bullets are hitting 4 inches low.I fired 4 shots and they are all that low.I have done lots of shooting but i dont know whats up with this.Anybody have any answers????Thanks

That's 2.5" high at 100 with close to your load...Should cross line of sight again at about 230 and 4 inches low at about 275 yards.

I adjusted it to make it do that...

Take this allwith a grain of salt.. the software is not a laboratory. It's just trying to explain what your saying.

I checked my scale for the tenth time it seems dead on,but if my shooting is right? your info says iam using 30 grs powder??

to get what roughly you reported , your bullet would have a bc of around 3.5 ( it is listed as 3.92 ) and it would be travelling around 2100 fps .....

this is what i got from the hornady website ;

so something is really out of whack

is your measurment of 100 and 200 yards accurate ?

are you getting signs of pressure yet ?

are these the bullets you are using ?

do you have , or can you use / borrow a chronograph ?

this goes back to are you getting signs of pressure , but are you sure it's varget your using , and it didn't get mixed up with some super slow burning powder ?

 

[hunter89]

It is varget as i bought and opened the 8 pound keg myself.I dont have a chronograph but iam buying one soon.It is one hundred yards.There is no signs of pressure that i can see and the guy that had the gun before me has 20 years of reloading knowlage.He worked up the load and i trust his word.That is why iam so confused???Maybe i will try shooting it again on thursday.I have looked up info in all my manuals and on the computer.I know it does not make sense???

good luck
half the fun ( if you can call if fun ) is figuring out stuff like this .

 

[hunter89]

Ya just when you get all your guns working great you go buy one more to have fun with?
I guess it keeps you thinking.Thanks for the info guys

What kind of scope rings and bases are you using? the reason i ask is i have had some problems with a few sets of weaver rings that were a bit out of spec. I switched the rings front to back and the problem went the other way, shooting much higher than i was supposed to.

 

[hunter89]

Scope is a leupold 2.5-8 and rings and bases are conetrol.This is my first time trying the conetrol rings??They are not cheap and seem soild.I will double check them.
