.264 Win Mag twist rate

Hi all,
I have finally gotten organised and had a chance to shoot the rifle. I used my Hornady Lock n Load bullet comparator to seat 143gn Hornady ELD-X projectiles just off the lands. This produced an OAL of 86.0mm with these long spitzer projectiles, which is well short of what can function through the rifles Mag box. This oal sees the base of the projectile positioned 2-3mm back into the body of the cartridge behind the turn of the shoulder. Based on my measurements Stonecreek, I recon the throat could be extended by 5mm or so!

Anyway I loaded some new brass with 62gn of AR2225, behind the 143gn ELD Xs, which produced an average of 2904 fps over 10 rounds fired. Unfortunately I was unable to group as the old Kahles 6x would not focus at all when I got setup on the bench to bore sight. Will need to sort something else out for next trip the the range, (obviously a 6x wouldn't necessarily bring out her best anyway).

I have added some pics here as previously promised. The rifle is in quite good shape for its age, especially for an Aussie import, and the timber has better grain than I expected for a Std model.

 

Hi Sraaw, Just looking at the pics of that "beauty" you picked up..... I have a L61R in .270W. Shoots great with 130gn projectiles. Have taken a few Sambar with it.
I am sure the .264WM would be a great long range game getter for you.
With s/n 91xxx with pin on side of bolt, (post '74 ) the butt stock wood on my .270W is almost a twin to your .264WM!! Same gloss finish.

Keep us posted on how it shoots, but I think we know!!

I would like to say there is no such thing as flamed walnut, if that rifle came from a guy named Ed.. I can assure you he was feeding you a big story... EDSAKO was banned from this site

 

I have a couple of 264’s. They both shoot 140 partitions less than an inch with IMR 4350 powder. They do just as well with 120 Barnes.

 

Hi there Sraaw! I know this is an old thread...

Glad you finally get your finnbear.

I was thinking if you finally measured the twist rate? Haver you checked OAL to the lands with other bullets than the ELDX 143?

Thanks!!
