Gunsmithing twist rate on 25/06

[magman687]

hey everyone i was just woundering if the twist rate for a 25/06 shooting 100-115 grain bullets would be best at 1/10 or 1/9 twist rate i dont know if it matters or not but its going to be a 28 or 30 inch barrel for 800-1000yard shooting

im mainly going to use barnes bullets but might put some match kings in it and i know ill use some Nosler Ballistic Tip bullets as well but like i said barnes will be my main bullet.

thank you all in advance

Re: twist rate on 25/06

and just to through it in here i was talking to someone who brought up what seemed to be a good point and that was with a 1/9 id have more spin drift but would it even be enough to worry about at 300 yards or just out at 1000yards or even at all.

sorry im semi new to long range shooting im this is my first hp rifle and i just wanna make sure im not blowing money on somthing that isnt going to be good for what im shooting.

Re: twist rate on 25/06

you were doing so well until you said "spin drift"

Re: twist rate on 25/06

Ummm...
I don't know a damn thing about spin drift...but my 25-06 AI shoots 110 and 115 with a 1:12...

Granted, these are hunting bullets, not long VLD's.

YMMV

Re: twist rate on 25/06

I would think about doing something other than a 25-06 for LR,especially if you are doing a custom barrel.

Re: twist rate on 25/06

forget spin drift... just forget it, it's a non issue, and what SANDRAT means is that if you're building the rifle that there are chambering that offer better bullets, better barrel life, better factory ammo and/or reloading components than a 25-06

Hard to find good LR bullet choices in 25 cal is all.

Re: twist rate on 25/06

ohh i see yes i agree 100% with you both but i hope it dont sound bad but im doing this for a gun that i just always wanted even if it isnt the best choice.

but after this i do plan on makeing a better rifle like a 7mm or somthing arounf it maybe even a 308.

but yes choice on bullets are very limited and to be 100% honest most of the shoot will be 125-300 yards but im going to take it out to 600 or so and hope to get a chance to go to 1000 just for fun.

but i had a old 25/06 many years ago and loved it all stock though and it got stolen and i just want a nice one.

and ok spin drift aside cuz i know it dont factor in very much if at all at closer range is 1/10 a good way to go or 1/9 or maybe somthing else all together

Re: twist rate on 25/06

I use a 1/10 twist in my 25/06 AI and I am shooting the Berger 115 gr VLD with outstanding results on paper and in the field..

Re: twist rate on 25/06

IMHO, for the basic .30-'06 case capacity, a long 7mm barrel chambered in .280 rem with a 1:9" twist rate and heavier (175-ish) high BC bullets should get the most efficient LR outcome for the given case capacity. Powders like H4350 and H4831 should be pretty straightforward.

The original .30-'06 is practically as effective on its own, and Lapua makes brass for this chambering.

Re: twist rate on 25/06

yeah thats another factor is the powder i was told IMR 3031 is a good all around powder but i dont know if it would be best for the 25/06 i plan on useing min loads then working up from there i know the 3031 is good in our 308 but im just not sure about the 25/06

Re: twist rate on 25/06

thank you very much ill pick some up to try it out

Re: twist rate on 25/06

Before you do, I may have been in error.

Yes, I used IMR-4320 and IMR-4350 at my Brother's recommendation, but after reading your prior post I did a double check on the Hodgdon handloading site. IMR-4320 does not appear anywhere in their load data, and it would appear it's faster than what should be called for.

I'm going to amend my recommendations to H4350 and H4831.

I apologize for any confusion I've caused.

Re: twist rate on 25/06

If it helps you out, I am shooting a 1:10 twist Brux, with 115gr VLD's (25-06). These are deadly accurate under 48.8 grains of IMR-4350. A 10 twist will handle them all.

Re: twist rate on 25/06

When posting what twist and bullet combo that's stable, it should be noted you need to give atmospheric data as well.

Something that's stable at 4500' ASL in 90* weather very well may NOT be stable at 1000' ASL in 25* weather (aka, Ohio)
