.223 where to st

[BigBlack]

I have a Remington 700 ADL in .223 22" barrel. I emailed remington my S# and they reported back that I have a 1/12 twist rate. I would like to use the Sierra Match King bullets and the Sierra Varmint Express bullets.

Anyone care to recommend the weight bullet I should start out with using my twist rate?

I will be reloading so any other recomendations on this combination will gladly be accepted.

The 1 in 12 twist was instituted to stablize the military 55 grain service bullet. You might go with Sierra's 52 grain HPBT or their 53 grain HP and see how they do.

<63 gr. http://sst.benchrest.com/shilentwist.html

Anywhere under 60 grains.

Hornady V-Max and Nosler Ballistic-Tip are also a very hard varmint bullets to beat for accuracy.

52 gr boattail Sierra MatchKing.

They nearly always shoot well and will give you a basis for comparison with other brands you might want to try.

I also have a 1 in 12" .223. A 26" 700 SPS Varmint in a HS stock. With the above mentioned 52 Sierra MatchKing the accuracy has been very impressive to say the least. I also have some 53 Sierra MatchKings to try. The best results with H335 powder and pretty good with Benchmark.

I would suggest something under 60 grs also. The bullet length has more effect than weight . Heavier bullets are generally longer so most use the weight in calculating twist. Google Greenhill Formula for Twist, there is a lot of good information in there.

My Fireball is a 1:12 twist and I get super results shooting a 40 grain Sierra BlitzKing and Nosler Ballistic Tips.
