Rate of Twist for .25-06

I have an Interarms Mark X in .25-06 with a 24 inch barrel. I want to know its rate of twist and which weight of bullet I should load. Currently I am handloading a 75 grain Hornady hollow point, and am getting poor groupings.
 
Most factory barrels are a 1:10 twist for the .25-06. Easy way wo check the twist is to use a tight patch, put a piece of tape around your cleaning rod and leave a little flap sticking up. Push the rod down the bore, when the tape makes a complete rotation mark the rod again, pull it out and measure the inches between the tape.

Your rifle may not like the 75 grain bullets as well. Could be you have copper fouling that needs to be removed as well. Have you checked your scope mounts and are you sure your scope is good?
 
sigsheprado I have had and shoot th 25-06 for years and have never had much success with the 75 gr bullet. However I had a couple rifles that shoot the 90 gr very well and most have shoot the 100 to 120gr well. I also have found IMR 4350 over all seems to give me the best results althought there are several powders that suit the 25 very well.

Your mark X should be 1 in 10" twist
 
much appreciated

Thanks for the tips. I had thought of doing the flag idea, but I didnt think it would work. But I will try it reguardless. Thanks.
 
My 25/06 shoots 87gr Nosler Ballistic tips great,but the 75gr Hornady VMax bullets don't shoot that good.
100gr and 115gr bullets are where mine shines,and the 117gr and 120gr bullets shoot pretty dang good too.
 
I had a .25-06 Ruger. It was not extremely accurate with much of anything but did best with the heavier bullets. Charles Newton and Savage settled on an 87 grain bullet to get 3000 fps in the .250 Savage, and that is about as light as a lot of the .25s will go.
 
Sig I just sold my T/C pro hunter 25-06and am in the process of getting a 700 rem XCR II in the 25-06. The T/C was very accurate but I am just not a single blaster guy.
 
I've got an early Ruger 77 with a 10 twist barrel that I picked up in '08 at garage-sale prices. I had never played with the .25-06 so I ordered some brass and some 117 Gameking bullets. My very first handload for that rifle, 50.0 grains of Reloder 22 went inside an inch at 100 yards and the chronograph showed a velocity of just over 2900 fps. That was good enough for me, and I said the heck with load development.

I've since passed that rifle along to a son, who normally shoots a heavy barreled 7mm magnum. He tell me that while he loves his heavy rifle, that the more he shoots the .25-06 the more he likes it.
 
Update for those of you interested. I was getting a 3 inch group at 50 yards with 75 grain bullets in the .25-06. Hornady called for 55 grains of powder with their 75 grain bullet. I cut the powder back to only 35 grains and started getting half inch groups at 50 yards. However this has cut my velocity from 3500 fps to roughly 2900 fps. Sometimes the book isn't always the best choice...
 
You sure about that load? 20 gr. difference in a powder load is a LOT.

I don't know I have ever seen load tables for 25.06 that show that much variance in a single weight bullet.

Geetarman:confused:
 
That much reduction is getting into the range we are cautioned to avoid, risking the S.E.E., which can supposedly demolish a gun with a greatly reduced load of slow burning powder.
 
sigshepardo,

Only listing I've for 25/06 Remington is 1 in 10".

Specifically . . . .Remington 700, 40-XB; Ruger 1, 77; Browning; Sako; Winchester 70; Savage 110, 112; and Thompson/Center Rifles

Your Interarms isn't mentioned but its a good bet that its the same as both the Browning and Winchester rifles.

If me I'd verify it like taylorce1 suggested.
