Actually it is basically a copy of Weatherby's Accumark contour just stretched to 30"

I was told it was basically a #3 contour.

Tom,

I'm no expert for sure, but that barrel looks much heavier than my #3 Krieger'd 22-250. I'm thinking more like #5 or so. Measure it at 26" and lets see what it works out to be, if you don't mind. Whatever it is, doesn't really matter, it's yours and your happy with it. I'd just be interested to see the dims. on it. Mine is back on hold for a little while now. The bottom metal is at Lee's place and the stock still on order. The rest will have to wait 'til work picks up again. Amazing what a couple weeks can do to your work load.

Anyway, back to the .264....

Well here is what I had Dan Lilja do...

Its my custom contour.

"378W30"
same as wby378 contour above but for a 30" finish length, muzzle .670" at 30"
30
1.25

Pretty sure my #3 Lilja is .625 at the muzzle

Just looked at Dan's website and his sporters are on a .008"/inch taper. His #5 is .700" at 27", so that's pretty close to yours Tom. #4 is .650" at 27", so that's a little thinner.

So you're pretty close to the same countour I'll be going with. That helps a bunch.

That's a pretty sonafahgun!!!!!

Whichever action you choose.......use a 26"> barrel.

A 1:9 twist will stabilize everything up to 142's. You don't need anything else even for elk or in Africa; kudu. Use the 140 Lapua Naturalis or A-Frame for big game.

I've found that RL-25 is good for every bullet weight up to 130..........anything heavier than that use VN N570 with a 215M primer. Or AA8700/H870.

The REAL advantage the 264 has over the 257 and 270Wby is no freebore.........mine have all been sub moa guns with very easy load development.

i've run .264 Win Mags in 1:9", 1:8.5", and 1:8"

1:8" and IMR 7828 is where you wanna be.

Yep, I agree.

Howdy guys looks like I am new to the 264 Win Mag group I traded for a Remington Sendero SFII it has a 26" Stainless with blue fluting with less then 300 down the tube and H&S stock. From our conversation yesterday it sounds like he has had a hard time getting good groups with it and not sure why. He has only tried a few powders and 1 or 2 bullets so I told him we should trade and I will give it a go. So last night I found this thread and began reading till I fell asleep. Guys you all are great there is a huge headach load of info here if you try to take it all in but WOW.
Keep it going

Lots of things to look at to improve the groups. First check the scope and mounts for fit and tightness. then check the stock fit as it may have a pressure point that is moving the impact point when the barrel heats the stock. A good cleaning can't hurt. Check the crown for dings. Don't over heat the barrel. Usually one of these issues will solve the problem. Also a quality powder scale when measuring loads for consistancy. You may have already considered all of these but just in case it doesn't hurt to check.

i'd try a known good scope and a trigger tweak.

my Sendero SFII .264 was a .5 moa rifle to 500 yards+ with a good trigger/scope

Bumping an old thread- Just got my .264 back from the smith, 28" benchmark barrel with 8.5:1 twist, cerakoted, laying in a choate stock. Looking for some load data for the 140 gr berger VLD's if anyone has a good starting point.

I wouldn't even know where to start with data for the fastest twisted barrel I have ever heard of...8.5 revolutions for every inch of travel...wow!

Use Retumbo, I'd start around 62-64 and work up; you'll max. out somewhere in the neighborhood of 70 grains, maybe less.

This looks like the place to share some load results.

I am still working with my first 264, but it is on its second tube.



The model 70 is a 27 inch Pac-Nor #4 three groove in 8 inch twist, in case I want to try the 142MK etc. The scope is an FF II in 4.5-14 ballistic plex.

The no 1 is my 7STW.

I have only just begun to wring out the barrel. So far I have been trying to make 3300 fps with 130 gr AB's.

71 gr of H1000 max (load from Hodgdon 26 at 3187 fps) actually gave me 3300 with the barrel well warmed previously.

On another day through a cold tube, it averaged around 3275 fps.
with accuracy right at 1 moa.

I am sure the rifle can do better so I continued to explore.

71.5 gr of Retumbo produced 3300 fps, but I have not grouped it yet.

I also have a string of cartridges loaded with various weights of Magnum. Probably get them over the Chrono this week end. And shoot a few groups.

I have a 340 Wea (Pac-Nor) in hand which I need to run out to 700 yds for a friend. I am hoping I can try the same with the 264 this week end.
