Re: 270 win load ?

Tried H-1000 w/169 gr WC prototypes but 7828 worked better.

Have a 27" bbl so velocities will be a bit higher than w/a 22"er.

For the 90gr I'd recommend 4895 for the 140 I'd recommend one of the RLs; 22 if bbl were longer.

Biggest difference (improvement) in accuracy came when I switched to NON MAGNUM primer. Load is now 58.5 gr RL-22 and CCI 200s. Velocity is just under 3200 accuracy hovers around the 3s. Bullet is 140 Hornady boat tail. Same load w/Nosler 130 ballistic tips give same accuracy and a bunch more velocity.

The best powder for the 270 that I ever had was N205 and N204 for the 90gr Sierra. I've heard that RL-22 is a "cheap" MRP?????

Re: 270 win load ?

I've been loading the 270 Win since the early 90's. Your advice so far it good. Any of these powders should work fine:
H4350, 4831SC
IMR4350, 4831
Re19, Re22 (and yes, these are made in Sweden and are temp sens.)

I do not read a lot about it anymore but one of my most favorite powders for the 270 for overall accuracy is AA3100, especially with a 140 grain bullet.

I tried magnum primers several times and did not notice a substantial difference in vel. or accuracy.

In my opinion, there are 3 ultimate powders for the 270: H4831SC, IMR 4831, and Re22. If you're looking for top vel. in your bbl, look to Re22.
