You will have to experiment. All weapons will show a preference for one weight or another. Stay above 55 g
it is a one in 12" rate of twist good for up to 55 gr. bullets may stabalize some 60 gr but heavier bullets may suffer in accuracy..... Turns out that ALL H&R/NEF .223 barrels made will be 1-9 twist starting in 2006. This is great news to those of us who want an inexpencive .223 rifle that can shoot heavy bullets.
1/9? Well, maybe. Most of these rifles were made with a 1 in 12" twist. This twist was judged best for the lighter varmint bullets (40-52 gr). Some newer .223 rifles are offered with 1-9" twists. Its best to check the rifle to make sure which one it is to be certain.
1:12 or 1:14. Stick to the very light bullets.
The Sako L461 Vixen in .223 caliber typically has a rate of twist of 1:12 inches. This means that the rifling makes one complete turn every 12 inches of barrel length. This twist rate is suitable for stabilizing lighter bullets commonly used in .223 cartridges.
The 1:12 or 1:14 are old recommended twist rates for the .223, to stabilize the shorter lighter bullets. 1:9 is considered optimal for the current heavier bullet (62gr for example) loading and yet will still do an acceptable job with the 55gr bullets. Look at loading data for bullets OVER 52gr and see what twist rate they recommend. sales@countrygunsmith.net
The correct bullets for a 223 WSSM are .224.
In a package
Yes but I would only shoot those loads with a 55gr.bullet or lighter.I believe the smith and Wesson model 1500 has a twist rate that is not made for the heavier bullets found in todays .223 ammo.
Twist is 1:12
Them twist rate of a Winchester model 70 rifle in .223 Rem.is 1"in 9".
The H&R Handi-Rifle varmint barrels in .223 made before the year 2000 typically have a rate of twist of 1:12. This slower twist rate is generally suitable for stabilizing lighter bullets, typically in the 40 to 55 grain range. Later models and variations may have different twist rates, so it's always good to check specific models for confirmation.
1- 12 twist
