Remington 260 and Criterion barrel

[Bill Daniel]

Hello to all. New member with a question. I am in the works to convert my Savage FCP Win. 308 to a Rem. 260 using a Criterion 28" Bull 1 in 8 twist barrel as soon as the household CFO approves my request. Any of y'all with experience have a favorite load for 800-1000 yards. Zak Smith replied with H4350 or R17 and Glen Zediker in his book "Handloading for Competition" notes VV 150 or Varget.
Thanks,
Bill Daniel

I have the same barrel on the rifle I just built, first build by the way, and Ive come up with a nice load. I havent shot it at 800-1000 yrds, but I guarantee its an accurate load so far.
140gr A-Max Hornady
BR2 primer
45.2gr RL19
2848fps

oops meant to write A-MAX

Hey Jerri. How long are you loading them? How far off the lands?

[jerrriley]

The C.O.A.L. for mine is 2.862. I backed it off .006 for now. Today was only the 3rd time to shoot it and first time for a serious session, it did great tho. I concentrated on shooting groups at 200yrd mainly, best was around 1/4-3/8. Best I can do with the scope I have now. The range by my house only has 300 max anyway, so I dont know how it would do WAY out there. I was able to hit some clays I hung up at 300yrd dead center without busting em. I think its a shooter.

Thanks, Jerriley

42.0-43.5gr H4350 with a 140gr-class bullet. The same charge of RL17 will be ~ 100fps faster.

For 130gr bullets, you might add one grain of powder.

My 26" 8 twist Criterion 260 tube seems to like the 130gr Berger VLD and 43.5gr RL-17 @ 2.94" OAL...3000fps+ with no pressure signs.

STANDARD DISCLAIMER: what works in my rifle may not in yours, start low and work up, etc etc.

@BoilerUP
the RL17 at 42.0 to 43.5gr will produce 100fps more than the 2848fps i posted? Thats what your saying right? No one ever has RL17 when I look for it so I have never experimented with it.

[BoilerUP]

Not exactly...

My experience with the 260 and H4350 and RL17 is that at a given charge weight, RL17 is about 100fps faster than H4350.

To get 3000fps with the 140 VLD in my barrel, I can use 43.5 RL17 or 44.5gr H4350. I've seen similar trends with the 140 Amax.

you guys going alot faster then me , where are you with the lands I run .015 out and with 38.9 gr of VN150 I split a case in half , but on crono i was 100fps faster at 37 then what sierra data showed for 2700 with 39.9 od n150 im 2700+ with 37 grs at .015 out

Are you guys loading at standard oal? I sure would like 3000 fps, going to assume you all used chrono's

[BoilerUP]

My 130gr VLD load (43.5 RL-17) is 2.94" OAL, which is roughly 0.010" off the lands.

Haven't fine-tuned any other loads yet.

It looks like the Rem 260 is as finicky about powders as its big brother the Win 308. ;) VN150, H4350, RL17, RL19, Varget...
Thanks fellows

[jerrriley]

The OAL is going to be diff for every gun, thats why you have to measure. Some rifles dont shoot the same powders as well as other ones do. its all about the harmonics that are created in your rifle from the explosion and the length of travel that the bullet makes before it reaches the lans. you just have to test what works with your rig

Does the 2.94" OAL fit in the magazine or are you shooting it as a single shot?

I run CDI DBM with Alpha Type 2 magazines and it runs just fine in the mag.

Prior to getting the DBM, that load fit and fed perfectly from a centerfeed blind mag (I think its 3.00" long).
