"The mother of all reloading setups"
So your the man to talk to about that, nice!
( another day perhaps )


@ txlongshotb4
Definitely purchased the Leupold Mark IV 3.5-10 today.
I did some reading and talked to my gunbroker/gunsmith/"gun guy" about it. He's the guy that I order everything through, very knowledgeable and has a lil gun shop at the range I goto.

YouTube. (
)

I should now have all the "first thing" parts coming in all together next week.
< grin >

Next, as 13fcolt pointed out... the ammo

Recommendations regarding specifics, technical, optimal muzzle velocities for hitting targets @ 100 vs 300 yards, sort of thing would interest me at this point.

EG: change of grain based on distance, etc.

I do see on mfg website they listed the rifling twist @ 1:10" for 150-175 Grain Ammo

I assume muzzle velocity is most important when talking about hitting object at various distances, and what, how much "damage" the round will produce.

EDIT:
Did some resaerch, found this:
"The .308 Win. has a nominal muzzle velocity of around 2620 f.p.s. with a 180-gr" but now reading further, i thing thats for a 24" barrel, i got a 20"

Did I mention I had to take Calculus 3 or 4 times ;\

EDIT2:
Found some awesome videos on YouTube
Understanding minute of angle... (

13fcolt, I feel your pain. Every time I stand in front of a cash register with a box of match grade in one hand and my debit card in the other, I feel your pain. This isn't getting any cheaper, and it seems like these days even reloading supplies are getting hiked...I never realized what a great gift I received when the Army would give me more ammo than I wanted to carry for free. I'd trade some of my benefits for free M118LR for life...that's for damn sure.
You've brought up a great point...Shooting is a very perishable skill, when it comes to accuracy...I am the same way. If I go without shooting for several months it takes me awhile to get my magic back. I've also noticed that my data changes every six months or so, particularly at long range. My scope data for 1,000 meters will not be the same as it was six months ago, regardless of how much I practice or any other factor within my control. I guess this just has to do with us being human...our bodies change, and thus so do the dynamics of how we use them for things like shooting-so practice is crucial.

Paul,
Great choice on the optics...you won't be disappointed. Just remember, however, that what you use to mount the optics to the rifle is just as important. Remember to try and get that objective lens as close to the hand guards without actually touching it as possible. LaRue Tactical makes some great mounts, as a suggestion.

As far as ammo is concerned, you seem to be looking in the right direction with the heavier bullets. Heavy bullets, ( 168 grain to 180 grain) tend to work a lot better for long range applications.

Muzzle velocity is important, but understand that it is not the most important factor in ammo selection pertaining to long range. The most important figure to look at when selecting a bullet for long range shooting is the ballistic coefficient, or BC, of the bullet. BC is a complicated thing...In a nutshell, it is a measure of the bullet's length and density against it's drag characteristics and aerodynamics in order to determine how well the bullet can cope against the forces of nature during flight over distance. BC .will be represented by a number, usually 3 digits, preceded by a decimal point. The closer this number is to being a whole number, (1.00) the better.As far as muzzle velocity is concerned, it is important in the regards that it must be repeatable.

To recommend some good factory loads for you to start with, Federal gold trophy match is good stuff in the 168/175 grain weights for long range shooting. Black Hills Match is also great stuff in the same weight...this is my go to for over-the-counter ammo. My absolute favorite ammo that I can get is Lake City M-118LR, which is the military sniper round...but it is hard to come by. The biggest issue in ammo selection is that rifles tend to defy all common logic in this category. I could have bought the next AR-10 to roll off of the assembly line after yours did, and they would both shoot differently with the same ammo...bottom line, you'll just have to feed your rifle what it likes, and you'll have to do a lot of experimentation to figure out what that is going to be.

If you're going to take on long range shooting, then you should seriously think about reloading your own ammo. Long range accuracy demands match grade ammo, and match grade ammo isn't cheap. Reloading your own ammo-even match grade ammo- is a pretty easy ordeal, but it'll cost you to get set up for match grade results. This initial set up fee will, however, pay itself off very quickly if you intend to do a lot of long range shooting.

Truthfully, I'd call out zfk55 as the reloading go-to guy. I've been rolling my own for awhile and I've learned from his posts here.

If you do decide to get invested in hand loading for long range, berger, lapua, & sierra are the primary sources for quality, High BC, projectiles. You will find these used in top factory ammo, like the popular FGMM which is still loaded with the sierra match kings. ( I don't personally care for federal ammo, but many seem to love the stuff ).




txlongshotb4, I hear that... I think I miss the ranges as much as the ammo. What I wouldn't give to have a popup range of my very own. I shoulda reup.

First post on this forum, Hello World

What is the first thing you did to your ar10t after the initial breakdown and lube?

Cheers,
~Paul


I added my Back up sights....The ERS and the FFG for the ArmaLite AR-10 Gas block.
The I went shopping...took about a Year to get it all together but it never stops...always something you will want to add...Just recently I added the MI MCTAR-30HD endplate adapter...
Congratulations and welcome ...
