270 Win RL26 advice

[thatguySHM]

Looking for some load advice and it's been a long time since I've been this far off. Remembered I had a jug of RL26 in the back of the cabinet, wanted to try it with a newer 270. Aliant only has data for 150 gr, I am using the 140 Sierra Tipped Game King. Max for the 150 Partition is 60.8, so I loaded a few up around 58.5, expecting to get high 2900s. Used F215Ms for primers.


Tested today, it was warm, approximately 85 and in the sun, but it was shot first from the AC truck. 58.5gr left me with a heavy bolt lift and 3181 fps with the Garmin. I shut it down there. I have a good load in the mid 2800s with Hunter, more I just trying to use the RL26.


Most of my use of 26 has been with 300 WM, any help is appreciated.

When working with an unknown combo I drop back 10% from a similar bullet and work up 1gr at a time to pressure.
You are using a 215 vs 210 what Alliant lists.

If you know anyone using a magnum I bet they'd be interested in the RL26. Almost seems a shame to shoot it in the 270.

Having used both RL 26 and N-560 in a 280 Remington, I would suggest using N-560 because of availability.

Sounds good, thanks everyone.

Between the mag primer and I'd bet that 140gr TGK being as long or longer than a 150gr Partition, definitely need to start lower. R22 can be very good in the 270 with heavier bullets as well.

Steve99, which 140gr Hornady bullet?
