Anyone shoot .223 ?

I'm considering swapping my .243 Win. Savage barrel over to .223 - mainly for target shooting.
I've discovered that the barrel life of a .243 pretty much sucks.

Any opinions or discussion on long-range shooting (maybe F-class and even varmints out to 1,000) with the .223?

Your dreaming..
500, maybe 600yds -under perfect conditions.

I varmint hunt with a true 1/4moa rifle in 223 & 50SBKs@3550fps. It's a 400yd rifle.

Another I hunt with, is 6br & 95VLDs@2975fps. I consider this a 700yd rifle.

1000yds is a long way. If you really want barrel life with this kind of distance, look around 6mmbr.com at some of the cartridges they like. It's a great source of info.

Do not worry you are not dreaming, just depends on the twist.

To go 1000 with a 223, you will need at the 1-8 twist to shoot the 75-80 gr bullets, and 1-7 to shoot the 90s. Some 9 twists will shoot the 75-77 gr bullets well but rarely the 80s.

AMU and USMC teams are shooting ARs with 1-6.5 and 90s at 1000 so it is being routinely done and very accurately.

I have a Savage LRPV with the 1-7, ballistically it is almost the same elevation and wind drift as my 308. Biggest problem with a 223 is spotting the trace or sometimes the impact due to smaller bullets.

Now if I was going to shoot Fclass Open, AND you reload, look at www.6mm.br.com for the 6BR variants such as the 6BRX, 6BRDX, 6BRBG etc. good barrel life, low recoil, great accuracy etc.

If you shoot Fclass, there are two classes, the FT/R is only for 308s and 223s. If you want to shoot the OPEN class, then any caliber. Suggest you stay in the FT/R class for now with standard rifles and bipods vs full blown custom guns and rests in the Open class.

One of the major keys to LR shooting is heavy bullets for the caliber AND the correct twist for the bullet and MV. if you have the wrong twist it will not work and it will vary for a boattail versus a flatbase.

For example, in a 6 BR to shoot the 95s most go with a 9 or 10 twist and an 8 twist for the 105-107 boattails. However, I am shoot a 6BRDX with a 108 BIB flatbase bullet that needs a 1-9 twist. We have already talked about the 223s.

in 30 cals for example, Seirra lists a 1-9 twist as being required for its 240s. However, that bullet was originally designed for the AMU shooting a 300 Win mag or 30-338 Mag at 2700 fps. Take a large case mag, push the MV to 2850-2900 plus and 1-10 twist works great. Faster the MV the slower the twist can be. LR BR guys are shooting the 300 Ack Imp with 187 BIBs and 1-13 twists. My 300 WSM Light gun shoots the 187 BIBs with a 1-12 twist at 3000 fps. Guess what, it will also shoot the 210s very well, where old school says you have to have 10 twist.

Something you may consider, if you reload, is a 22-243. This would work well in your gun, you already have the correct mag and bolt face. I know of guys that use these with 75 gr. Amaxs and have made kills in the 600 yard range with ease.

Thanks for the responses, gentlemen.

Bounty Hunter,
I will have to go with the .223 vs. the .308 due to recoil issues for me. So you think I will be at least somewhat competive with the 75-80 gr. bullets and a 1:8 barrel twist?

The 6br, the 6XC. and the 6.5 x 47 should work for targets and give plenty of barrel life. These are as easy ot shoot as the 243 Win. The 22x243 would likely be worse on barrels than the 243 Win.

I have only shot 1 F-Class match in my life and that was with a 223 Rem, 1/8 twist barrel and 80gn Sierra bullets. I shot a possible at 300 meters, dropped 3 points at 500 meters and dropped 9 points at 600 meters - but the wind was pretty strong by that stage. I lost a few points before I worked out to hold ENOUGH for windage. I found the fast twist barrel 223 a good fun cartridge combo to shoot out to 600 meters.
