Default Barrel Twist Rate question

I have a 25-06 Rem and the barrel twist rate is 1-10 so I was curious what is the recommended max that I shoot with this twist rate? does speed hae a role in this too? I am just getting into reloading and I am pretty sure I will start with 85gr Noslers but I would like to try some 110s maybe even a 120gr bullet and see what the gun does.... I am mostly shooting coyotes but I shoot for fun a lot....I dont save the pelts just want to get rid of the stupid yotes...thanks in advance

I personally don't know much about this but just got off a website talking about twist rates a few minutes ago. Heres a link to the site. Scroll about 1/4 the way down and you'll see "Rifling Twist Rates". Hope this helps a little.

From everything I have read, for the .25 bore cartridges the 1 in 10 is recommended for bullets up to 100gr and a 1 in 9 for anything heavier. There are several variables that come into play with twist rates however. Velocity of the bullet, length of bullet, barrel length as well as a couple others, all effect twist rate and bullet stabilization. Also, every barrel is different - one barrel with a 1 in 10 might shoot 120s just fine while another won't. The recommendations are just guidelines so you'll just have to try a few of each weight and see what your barrel likes. A good compromise would be the 110gr Accubonds, should work well for yotes or deer. Good luck!

Twist formulae's aside, the .25-06 normally has a 1:10 twist and will stabilize just about any bullet up through 117 grains. When you go to the 120 grain, though, some of the longer ones are a little close to the edge of stability.

I use Shilens' website tohelp me make decisions like this. Different barrel makers will list slightly different twists for the same weight bullet. This is not an exact science. I do agree with Galngbeardyou may find a barrel that is not optimal for that weight bullet butshoots it exceptionally well.

120 grain bullets normallywork just fine in a 1/10" barrel on the .25/'06. In fact, that twist is acceptable for any and all "normal -weight" bullets in .25 caliber..... (85-120 grains of regular length- a VLD of 120 grains might cause difficulties)

I have seen some 60 grains bullets that are in 25 caliber...They are totally different design than say a 85 grain and I figured they were specialized for maybe the 25-20 or something...but have any of you ever used these? Also Hornady has a nice looking 75 grain V-MAX how well do these bullets shoot at long ranges and whats their ballistic coeffient

I wouldn't go lighter than the 75 V-Max. The ballistic coefficient is so much lower on the 60 grain that the extra velocity you get is eaten up pretty quick as the bullet flies through the air.
