Hi,
I am new to reloading and this the first time I've posted. I have modern reloading 2nd edition ordered. I'm planning on reading thru it a few times before asking too many questions. Just wondering if anyone can tell me if this book or others will have suggestions on bullet selection for certain barrel lengths and rates of twist. Or if it matters.

Cheers
 
Yes it does matter - lighter bullets like slower twists ie 1-12 you can shoot heavier bullets with faster twist rates 1-7 upto 1-9 it all depends on your application - type of bullet your reloading etc

the book is a good start read it over a few times
 
Twist rate is relatively independent of barrel length. Bullet weight and especially bullet length are important. If you are shooting Berger bullets they do a good job of giving you the minimum twist required. Here are some helpful links:

Berger Quick Reference Sheet - gives somewhat conservative twist requirements for their bullets

Berger Twist Rate Calculator - Calculates more specific twist requirements for their bullets and others

Bullet Lengths - A data base of bullet length for various bullets to use in the twist rate calculator. You will have to source the BC's from the other bullet manufacturer site.

Suggest you amend your profile and show your city, so a local CGNr can come over and help you out.

Let us know what rifle you have and the caliber and the intended use. We can then give you more useful advice.
 
Thanks everyone for the replies and advice. I have three rifles, all savage. 11 scout, 11/111 fcns(243) and the last a 11/111 trophy hunter XP (233). I'm a little confused about the 223 right now, I thought I remember it being a 1:12 but savage's web site says 1:9. It does group federal American eagle and Winchester 55g fmj's pretty good tho. Mostly for target shooting but I'd like to have a few hunting rounds on hand.
Thanks again

For the gun you are not sure about the twist on, here is how to check it. Take a cleaning rod with a bore brush and wrap one patch around the brush to make it fit fairly snug in the barrel. Just start it in the barrel, and mark the top of the rod with felt marker. Measure the length of the rod sticking out. Slowly push the rod into the barrel while letting it rotate with the twist. If it is a 1:9 twist the rod will make two full turns in 18". With a 12 twist you may only be able to measure 1 turn (in 12 inches), unless you have a barrel over 24".

I had a role in convincing Savage to switch the 223 to 1:9. That as about 20 years ago, so your 223 is most probably a 1:9. It is capable of good accuracy.

Bullets that will do well are the Sierra 60HP, 69 Match and 77g Match. The Hornady 68 and 75 Match are also very good.

Your rifles will do better if the actions are bedded. This will improve accuracy and consistency.
 
Thanks for the input, I am looking into bedding now. That should keep me busy until my equipment arrives and I can get some components.

I'm in your neck of the woods been reloading for 6-7 years now. I'm by no means an expert but I've been reloading for .223 and .243 all for savages if you need some help or get stuck send me a pm happy to help if I can. Most all savages these days are 1-9 twist rates. In your. .243 try 65-75gr bullets using a medium burn powder like IMR 4350. For the .223 try a 55gr v-max with Varget or benchmark always start loading at start loads from a good manual and work up. I work up in .3 gr increments until I get a good grouping or pressure signs appear
