Mike,
I'm going to be contrarian here and recommend you buy the rifle in 30-06.
I dont believe you've reloaded for the 30-06 or have much experience with it because of this line from your post "I thought about 30/06, but didn't think the slight increases over .308 were worth the expense/effort...
Great Points Mike!
I continue to be shocked at how ill-informed people are and their belief that the more expensive a weapon system is, the more effective it MUST be or that if the military uses it, it must be awesome (reference the M110...a more accurate and reliable rifle can be built for 1/3...
I'm going to respectfully disagree with your assertion.
The quote/paraphrase from the instructor is an indication of lack of familiarity with the vintage weapon systems. As previously mentioned, on an as-issued basis, the vintage rifles are just as capable (defined as making hits on man-size...
Chris,
Good to see you diving in with both feet. Its a little difficult to make a "call" at this point, but i have the following pointers:
1. If you can get a higher magnification scope, please use that instead...aim small, miss small. If you must stick with your current scope, change out...
Chris,
175gr SMK load data is interchangable w 178gr AMAX load data in most rifles.
I've never played with 4064 powder, so i don't have any insight for you expect perform an OCW test to find the accuracy node(s) in your rifles.
If you happen across some H-4350 or IMR-4350, the accuracy nodes...
Chris,
Your post is a confusing, so i'll assume that you want to stay with the 30-06 but want a load that will be reliable for 600yard plus?
Your rifle clearly has potential...any rifle that will shoot crappy ammo (corelokt) into a sub-moa group is something special...
The question then...
You are lucky Jerry.
This means that you can take advantage of the "heavy for caliber bullets" in your rig.
You can run the 185/190 Bergers, the 208AMAX/210 Bergers and seat them out with enough case capacity to exploit their BC potential...if you are willing to single-load.
It does nothing...
Why did you purchase a 20" AR-15 for long range shooting?
It's MUCH easier to do what you've described with a 24-26" barreled AR.
900yards with the AR-15 & factory 77gr bullets? I hope you know quite a bit about wind reading...
O'Cullkillin,
You got 2800ish ft/s out of a 30-06 w 208AMAX and no pressure signs? Game Changer!
I can't wait to see some of your groups. If you get an accuracy node in the 2750-2800ft/s range, then this changes my plans for 1,000yard prone matches.
Ryedaddy,
Your best bet (velocity wise) is with powders such as RL-17 & 2000MR...but go for accuracy over velcity.
I hope this starts to let you know that all the BS about how awesome short barrels are is promulgated by people that don't shoot for precision/accuracy.
I have all the Geissele triggers...Four (4) NM triggers, and 3 of the SSA-Es that you are asking about.
Both are very nice triggers with a properly tuned NM trigger being unbelievably great. They usually ship with 3 sets of springs and with the "match rifle springs", you can get the pull weight...
