Range Trip - 270 Winchester - 150gr. LRAB & RL-26

[Johnly]

I dipped into my last bottle of RL26 to see how it performed in the 24" barrelled Remington 700. This rifle has displayed sub-MOA accuracy with the 95 gr. TTSX and 130 gr. NBT bullets.

The load tried today used some 150 LRAB bullets I traded for seated at 3.492" OAL which has a .020" jump into the rifling. I started with 59.5 gr. of H4831 that punched an ugly 2+ MOA group at a measured velocity of 2879 fps. Next up was a load of 61.0 gr. of RL-26, the accuracy improved to 1.2MOA, better, but well below that of other loads. The velocity.... drum roll.... was 3083 fps. Wow! I'm going to try some different loading lengths to see if I can improve on the accuracy. Needless to say, the velocity is impressive and there are zero pressure signs.

What is your twist?

 

[Johnly]

According to Remington the twist rate is 1/10.

It will stabilize as it does for my blr 22". Yes, it's a 10 twist also.

My 24" Brux is 1-10 as well. It will put 150 Tips in .337". speed is just over 3,000FPS with RL26

I have never seen a 270 Winchester not in a 1:10 barrel. 150's are at the top end for standard 270win's and I use 52.5g of H4350 (AR2209) for pushing 150's out of my BRNO ZKK in 270w and it shoots sub MOA with it all day long. Everyone I know that shoots 150's out of their 270win use that powder and similar charge to good effect......not that I am advocating you do the same, you'll need to safely work up to or exceed that yourself based on your set up

Well I have the same gun, Rem 700 and I am shooting the 150 ABLR's as well with 61 grs of RL 26 : Ditto! Vel here is 3100fps so pretty much identical set up. Mine struggle's to group 1.5" .......... But it drops Moose like crazy.
