Nosler 55GR Ballistic Tips in 1-8" AR?


November 17, 2008, 01:51 PM
Hi all,

I found a decent deal locally on some 55gr Nosler Ballistic Tips (that is to say, the price was average but the bullets were actually IN STOCK) so I picked up four 250 ct boxes.

I recently picked up a RRA NM 20" varmint AR and I am wondering if these 55 gr bullets will stabilize well (and not vaporize) out of the 1-8" barrel w/Wylde chamber. The primary uses will be for varmint/predator hunting and paper punching under 400 yards, but mostly 50-200 yards. I also have a CZ 550 in 22-250 I intend to use the bullets in.

I know, I know, ask the question AFTER I buy the bullets :p

I was going to start by throwing some TAC over a CCI400 primer in Winchester brass.

Any general thoughts?

You can't really over-stablize a bullet.
(Well you can, if you spin it so fast it blows up in the air)

Your 1/8 barrel would probably shoot 40 grain bullets really well.

I think you will be very happy with the 55 grain BT's in your rifle.

Getting a .223 to vaporize a bullet would take a faster twist than you have.

I was just say'n!

No, a 1/8 or 1/7 .223 will positively not vaporize a 55 grain Nosler BT.

I wouldn't put any money on a 40 - 45 grain Blitz, TNT, or some such though.

Load 'em, shoot 'em. No worries.

Military still uses M193 with the 55 grain FMJ in their 1X7 twist M16A2's with no issues other than they've got a little different trajectory than M855 and don't penetrate as well.

I will check my Nosler book when I get home to see what data it has on the 55 grain bullet, but I do know that 27.5 grains of H335 with a 40 grain Nosler shoots like a dream out of my 16" bull barrel Olympic Arms AR-15.

I have the same exact rifle as you and mine loves the 55gr Nosler Ballistic tips with IMR 4046. It will shoot under 1" groups at 200 yds with no wind.

I have not tried the 60 gr Nosler Ballistic tips yet but would like too.

I have always found the 1/7 barrels like the heavier bullets.... 55ís have always shot like chit from any of my miniís with that twist rate... but the 62 - 65 grn bullets.. do a much better job (using my reloads) for each particular gun I have with that fast of twist rate... of late I have used 55 grn with 1/2 inch grps out of a sps tach. rem 700 bolt... 1/9 barrel using factory ammo... cant wait to work up loads for this gun cause it already looks good .... but again my experience has always shown that the faster twist rates like heavier bullets (223).... but that is my experience with the guns I have.... perhaps you are seeing a variance with different types of guns you have. cause mini's are not that easy to group....

I shoot the 55's in HP @ 200 in a 1X7,, my hunting upper is an old chrome lined Clot 1X7, and I get 3/8 to 1/2 in 10 shot groups with it.
Easy to find a good load with the Nos BT.

Thanks guys for the great replies! I think I am going to need to just load up some 55 grainers and see how they shoot.

I will report back!
