Hey all.

Gonna take my 10FP and model 70 out to the range to dial them in (if its open....)

Had the 10FP out last summer and started to dial in at 100 yards, but moved scope back for eye relief.

Both scopes have target turrets that will be re set, once I get a good group at 100 yards.

What do I need to know or keep in mind?
 
I guess the calbre you are shooting would also be pertinent....you will likely need an MOA scope base on your rifle to shoot to 1000M dependant upon what calibre you are shooting....this would compensate for the lack of adjustment in your scope for that extreme a range...also depends on your scope and how much internal adjustment is there...
 
For the 308 I have a wack load of factory ammo. Different brands and grains. Bought a case of Federal Gold Match.

Wondering how to go about deciding what shoots best through the rifle. Use one make/weight to dial gun in at 100 yards. Do I adjust when switching to another make/weight shell? If hits are a little of the X.....

Stuff like that among whatever else should be done.....
 
I using my own loads with .30-06 caliber, powder IMR3031, bullet - Sierra Match King 165 gr.

Ragarding adjustments - set it for 100 yd, if your max distance 500 yd. But for the distance 1000 yd., set (zerro) at 300 yd.

Do you have a ballistic report on your weapon and ammunition? If you need one, I can do it for you, I just need all info about your rifle and cartridge you are using, plus the scope info.

Having a wack of ammo from different manufacures is going to make things confusing. Your rifle will probably love something in the 168 grain area for what you want to do. I have used Federal gold match, and it is great ammo. Black hills has excellent reviews but I have never used it. Best ammo to use is one's you do yourself but sounds like you want to stick to store bought which is ok but you will have different results with different lot #'s, in close not significant out to 1000 it will show.

Every rifle shoots a bit different even from the same manufacturer, a ballistic program will put you in the general area but the only way to get pinpoint repeatable accuracy is to shoot the distances yourself and make a record of your points of impact and come ups in MOA. I would recomend doing it in 50yrd increments after 300yrds out to 1000 its going to eat up a fair bit of ammo, but by the time its done you will know your rifle, have improved your shooting skill and have the data to dial your scope into any range and successfully produce first shot hits. Windage is another issue you will have to deal with, If you are interested PM me and I will send you a great easy to understand article on the mathmatics of windage, leading moving targets, mil-dot rangeing and other tips for LR shooting.

Hope this helps

FWIW my LE2B hated Federal GMM.

I shoot off my bipod exclusively and use a rear bunny ear bag when I'm shooting off the bench. Once you get a good group at 100, then start figuring out how far you have to "come up" at 200. Meaning shoot at 100 and zero, then shoot at 200 and see how many MOA low you are then come up the requisite number of clicks. Then to 300 and so on.
 
I shot some Lapua 308 168gr match loads last weekend out to 500 yards. Final score with the first time shooting that distance was 49-3x. Lotsa Learning to do, rifle was a t3 tactical (1/11 twist, 24" tube) with an elite 3200 10x on it.

What a blast, was able to keep a decent group on the 500 yard 5 second snaps too!!

Bought the ammo from hirsch precision, not cheap but if you take off the cost to by the brass, which I had too anyway it works out to about $1.00 / shot (ammo, shipping and taxes included)
