I am getting my M700 re-barreled and chambered to 7mm-08 Rem. The gunsmith I use recommends a 1-10 twist for bullets up to 140 gr. and 1-9 twist for bullets 150 gr. or more. (This gun is primarily for hunting deer.) I would like to be able to load this gun mostly for 140 gr. bullets but have the option of a heavier bullet if I ever draw a PA elk tag. (Possibly 150 gr. Partition.) What twist should I select? If I go with 1-9 twist, can I shoot the light bullet weights? I am assuming, if I select the 1-10 twist, I am stuck shooting 140 gr. or less bullet weights. Also, I am not sure about stock choice. Is the McMillan Hunters Edge that much better than the Bell & Carlson Ti. The McMillan Hunters Edge costs twice as much as the Ti if not more. (I am trying to put together a nice carry rifle in the 7.25 lb. range) Any help would be appreciated. However, I have my heart set on the 7mm-08 Rem chambering.

What about the 1 - 9.5"? Remington uses a 1 - 9.25"... Seems a 1 - 9.5" would pretty well set you up for either or. Pac-Nor barrels offers a 5 groove 1 - 9.5"...

Consider selling the 700 as is and upgrading the entire rifle at the same time. Look at other brands and designs.

As for the twist always get the slightest faster one. The standard on the 7-08 must be around 1-9.

The gunsmith I use prefers to use Hart barrels. They only come in 9 or 10 twist. No 9.5 twist.

Make sure the 'smith is clear on your weight goals. Hart blanks come with a lot of full diameter shank, so have him cut it short.

You can do anything with 120 grain bullets. 120 NBT's for deer. 120 TSX's for anything tougher.

1-9 twist. Don't overdue it on shank length or barrel contour. Mcmillan Edge.

I know I have said this before, but my son harvested a cow moose w/ a 120gr TTSX from his SS Mdl 7 7mm-08. I certainly would use this on a bull elk.

Hart has a bunch of contours programmed into their CNC lathe. They could just duplicate the factory contour to drop right in the Ti stock.

The matching of twist to the exact weight bullets you want to shoot is a waste of time IME.

My 7-08 is a 1-9" and it shoots everything well. I see no point in a 1-10".

I don't know what all is going into your build regarding glass and barrel contour but you should be able to use a standard fill McMillan and still reach your goal weight.

I would go with a 9 also..now, what about neck diameter and freebore..very important IMO..do you even know what reamer your smith has or do you consider them all equal as long as they will shoot the 7mm08..Oh, pay the money and get a McMillan..maybe even a regular fill Mt Rifle with nice camo color and a number 2 contour barrel with a short shank length..

I have a Browning x-bolt, micro hunter. I believe the twist is 1:9.
Shot 120 grain Rem. core-lokts they shot crappie.
Tried some of my handloads. 139 grain GMX with 41 grains of 4064 moa all day long.
Do not know if that helps. I think the longer bearing surface of the "Mono" bullet helped it.

Any idea what the Winchester featherweights twist rate would be? I don't see it on their site...

harv3589,

Winchester uses 9.5.

On the website, you can click on each of the calibers listed under the different gun models & you will find more details such as twist.

M70 FWT 7-08

My 708 had a 1-10 twist and it stabilized up to and including the 168 SMK. Unless you are shooting 175 and 180 SMKs or 168-180 Berger/JLKs, the 10 twist is perfect.

My most accurate load was with 168 Sierras and Varget.

My next best load was with 110 TnTs; that is quite a range.


I guess I am the only one posting on this thread that has actually used a 10 twist and it works great. I see no need for the 9 twist unless he is shooting the VLD heavies.

I like everything about this except the Hart barrel. I have used my last Hart!!!
