270 and Reloader 23

[Shane]

I was wondering if anyone has any experience with the 270 and Reloader 23? I will be using the 140 gr AccuBond as well as a 145 or eld-x from Hornady. I load some of the 145 gr with h 4831sc between 58.2 gr. and 59 gr. Increasing by 2 tenths each time for a ladder test. I would like to try the Reloader 23 but can't find any info for this combo. Thanks in advance for any help you guys can give me.

Hopefully, this will give you some intel to stimulate your thinking. Good luck on this project.

Yes, I use Reloder 23 in my 270 Win. with 150 gr. BT's. It is an awesome combination. With the lot of powder that I have I am getting 2,880 to 2,900 fps with only 55.8 gr. of powder. I have a large chamber. So start low and work up. I started low and was surprised with the velocity. I posted some results way back in 2016. I will see if I can find the post.

Read that thread Dan and those are some excellent results, somehow missed seeing it when you posted it up in 2016.

Enjoy that 140AB! It’s a great bullet and has put down a lot of elk for me. It also seems to shoot well out of everything I’ve ever put it through!

It also whacked my largest bull to date out of my 270 WSM..

If you can find some, RL26 is amazing in the 270 Win, at least from what I have seen so far. I have had an 8lb'er of 23 for going on 2 darned years and still haven't broke the seal since it seems like anything I would use it in, 26 is faster!
