I have been ofered a very good rifle in .223 Remington. The sole problem is that it has a 1-in-9" twist.

I understand that this twist is for people who want to use 60 - 70 grain bullets. I am not interested in shooting anything other than 45-52 grain bullets.

How will the faster 1-in-9" twist affect the lighter 45 - 52 grain bullets as far as accuracy is concerned?

1/9 is a good versitle twist in the .223. In general you can shoot anything up to a 69gr OTM bullet in them without any problem. My 1/9 like the 52gr Sierra Matchkings about the best.

Don't bother with Hornady SX in it.

That twist rate shouldn't be a problem.

I agree....and the Sierra blitz will also come apart when driven to top velocities.....

However most lighter bullets won't be a problem....

I've fired speer TNTs in the 1:9 and got away with it but others have not been so lucky.....

The V-Max bullets seem to fly quite well in the 1:9" barrels....only the very fragile bullets come apart and it's not many of the crowd.

I have a Rem model 7 with a Shilen barrel in 1 in 9 twist chambered in .223 AI. It shoots 40 grain to 69/70 grain bullets very very accurately and is equally good with several different 40's and 69 grain Sierras and 70 grain Barnes. It will not stabilize 75 grain Amax bullets however. You will be fine for your intended use. I would do a 1 in 8 next time for my uses.

My AR has a 1:9" twist and I've never had any problems with any bullets from 45-70 grains. Mine really likes 50 grain Vmaxes.

I have a Ruger varmit in .223 thats 1 in 9 and it shoots very well with the 40gr V-max and 26.5grs of H335.

I used to have a 9 twist 3 groove Pac Nor barrel on a 223 and never had a problem with any bullet we tried. Put the same barrel on a 22/243 and as soon as the velocity exceeded 3700 fps the only bullet that would make it to the target was a Ballistic tip. Switched to a 9 twist 6 groove and never had issues with anything but some thin skinned bullets that were limited to 3400 fps by the bullet maker. There might be a few bullets to avoid, but for the most part a 223 just doesn't have the powder to drive very many bullets past 3700 fps. So unless you have your heart set on 30-35gr bullets you should br okay.
