I guess I meant any AR for varminting--ammo for varmints and that kind of work not match stuff
An AR is going to be grouped by a few characteristics regardless of cartridge/caliber.Can you please help me understand the term "plain AR" better. I am trying to see where my ar fits
Thank you, this is an educational analysis.An AR is going to be grouped by a few characteristics regardless of cartridge/caliber.
The barrel length/profile and the twist are the top considerations.
To start with, the twist and chamber details dictate what ammo you expect to be able to use with stability.
The barrel length and gas system details dictate what loads will give reliable function.
We will leave full auto and suppressor discussions alone for now.
You stated 1:12 twist, which dictates the lighter end of the bullet weights/lengths range.
That also implies magazine length ammo, typically <= 55 grains.
The length and profile of the barrel are now going to dictate two more things.
One is how many rapid shots you can expect before the barrel gets too hot, and two is what velocity that ammo will make.
For today, these should give you enough to think about, 1) twist, 2) chamber, 3) barrel length, 4) profile.
We consider this a short range rifle because it is 1:12 , meaning best use is well under 400 yards. The bullet will certainly travel farther, but beyond 400 yards the typical dispersion and energy level means it rapidly becomes ineffective.
Now, just an opinion, take it or leave it.
Grab some decent middle of the road varmint or lighter target ammo, and go have fun. You don't need to burn expensive top quality match ammo in your 1:12 unless you left something out of your story.
The powers that be are trying to set up the next ammo frenzy and it appears as if 223/556 is their focus. I would go grab some stuff ASAP and see what you like before you don't have a choice. Try several brands and types up to 55 grains and see what you think, then stock up when you have picked your favorite.
You can try ammo out to see what suits you.Thank you, this is an educational analysis.
If you can, please ask any details about the build to finish your line of thinking - i refer to "unless you left something out of your story".
Just to provide some consolidated detail:
- Rifle length
- Shilen 223 math barrel with the head spaced bolt. Shilen told me this barrel can handle up to 63gr ammo. And as I understand, they will guarantee the barrel to be 0.5MOA or better
- Wilson combat BCG
- Wilson Combat Billet Upper/Lower
- Adjustable Gas Block
- Rise Amament ICONIC 2 stage trigger
- Arken EP 2-25 optic
Out of interest, I want to try and at least 0.5 MOA out o it, Benched, too heavy to try and do that off hand
thanks
https://www.sportsmans.com/shooting...gr-v-max-pt-bt-rifle-ammo-50-rounds/p/1319999I have had very good luck with Fiocchi 40gr. V-Max factory loads if you can find them. They shoot very good in my 8 twist barrel and should shoot great in a 12 twist. Plus they were cheap. I keep them in my Thermal rifle.
This is a FABULOUS combo (Berger 52 Match and LT32). Using that same powder, you will likely find that you can get in some great practice using less-expensive Nosler Custom Competition bullets and, for varmints, the 50 and 53 V-Max. Works in my 1-12, as well as my 1-8 and 1-9 twist. great. If the LT32 doesn't do the trick, try Reloader 7 with those same bullets.If you handload, I would recommend Berger 52 grain match and 52 grain varmint (yellow label and orange label, respectively) and would suggest LT-32 for powder. The bullets and powder recommended are readily available, right now.
My Ruger 77 with a 1:12 twist doesn't shoot a 55gr that well. 3/4" is its average. Trying 53s 52s, and 52s to try to tighten things up.Sig, Sierra, Berger, Hornady with the lighter weight (under 60 grain bullets) for your 12 twist. To maximize the potential of your rifle, you may want to look into hand loading.
