264 Win Mag Velocities W/140's ??

[260shooter]

Thinking of a 264 Win Mag build. Looking for velocities with 140 class bullets, 140 A-MAX's in particular. Include component details and barrel length along with velocities please.

I shoot a 264WM with a 25" barrel and get 3122avg with 140gr Accubonds and 60gr of H4831. This is not a hot load, but shoots well in my rifle.

Get a 8 twist barrel for 140 gr bullets. Get all the barrel length you can, min length 26" or you are wasting your time. I have a 27 3/4", all I could get out of a 28" blank, 9 twist and shoot 130 gr Nosler AB bullets. With Retumbo I get 3350 fps. You should be able to get 3200 or so with a 27".

I ran 140's at just over 3350 with Retumbo and a 27" barrel as well. Barrel didn't last long at those velocities is all....around 700 rounds.

Thanks guys. TMR 3350 with a 140 would be a smoking load! I am hoping for around 3200 with a 26" barrel. Is Retumbo the go to powder for this velocity?

Retumbo seems to work well with this case. The load I was using at 3350 was a little squirely sometimes. It shot ok, but I dropped it back to around 3200 and it seem to come together a little better. I know a couple guys that are getting 3200 out of a 26" barrel using Retumbo and H1000, I will see if I can get their load data.

68 grains of Retumbo, WW cases, 215M primers with 140 grain VLD's gives me 3166 fps with a 26 inch barreled Rem 700 CDL. This load is not excessive in my rifle as I've got 4 loads on the cases now and primers are still tight.

What OAL do you load them to?

Thanks guys

Looks like Retumbo will be a good place to start. Anyone shooting the 140 gr A-MAX in the 264 Win Mag? I see Nosler also makes a 140 gr Accu-Bond. Has anybody tried this bullet out?

3.445 is about .010 off the lands in my rifle.

Start your loads low and work up. It depends on your chamber and mine is a tight custom chamber and 66.5 grs Retumbo is as high as I can comfortable go. 67.5 left ejector marks on the case and the primer pockets were stretch. Ig you can use 68 gr with 140's you must have a larger chamber. I have a 9 twist and shoot 130 Accubonds and they are really good.

I have a custom barrel with a 1-8 twist. What would a good starting load be for Retumbo and the 140gr Berger?

 

[apexmtnman]

I have two 264's and both will shoot 68 grains of Retumbo with no pressure signs. One is the Rem factory gun I mentioned in my first post, the other is a custom Stiller action with a Broughton barrel 1 in 8 twist, chambered by Stiller. The Broughton barrel has a little bit longer throat as I can seat the bullets out to 3.465 to touch the lands with the Berger 140 grain bullet.
I know some guys shooting 69 grains of Retumbo and Berger 140 VLD's in their guns and getting a little over 3200 fps out of them, but case life is not as good.
