The first three powders I tried in my .270 are H4831, H4831, and H4831. Then I messed around a bit with H4831. Found a pretty good load with H4831, and decided to stick with it.

Seriously, if it's a .270, why look elsewhere?

I hope you accept H4831SC as a "friendly amendment" :)

For 20 years I used only H4831 in my 270. I did try out H4350 and RL-22 but didn't find anything better than H4831 for accuracy and velocity. Then I tried RL-26 a couple years ago when it first came out. Got 3100 fps with 140 grain Bergers and groups were just as good as with 4831. I think it's the best powder ever made for the 270. Too bad it's in such short supply. Lucky I bought 5 pounds before it became scarce.

Yep. Too much good stuff happening with new powders to rely on the old standbys. mtmuley

Honest question about chasing max speed in a 270. I've only been reloading for about 5 years now and still have a lot to learn. In the 270's I've found a great load with a 130 grain at around 2930 (chrono) and stopped there without the need to try and max out. What does an extra hundred fps really buy? Looking at ballistic charts, the difference is only a few inches at 400 yards. Seems negligible to me.

You're right, 100 feet per second isn't enough to make much difference. I just always like to get the full potential out of a cartridge, if possible. But, accuracy trumps everything. Having said that, you should be able to get at least 200 feet per second more than that with a 130 grain bullet.

60 grs of h4831 behind 130 gr Nosler partition has worked for me in two rifles for 30 years. Doubt I’ll be switching anytime soon😄

While H4831SC is where I start with .270, my win1885 really liked H4350 with 130gn TTSX, so you may want to try a few powders.

I'm really slow to try new stuff. always figured if it works, don't fix it! Don't have a 270 any more and don't remember what I used when I had one.

I'm using Hybrid 100V right now...140grain Partitions are going right around 3000. This rifle is going being switched over to non-lead and I think H4831SC is where I'm going to start.

RL-26 should be able to push a 150grain bullet over 3000fps easily though that stuff may be hard to find.
Do you like that hybrid 100? I am going to try to load that for my barnes 130 grains.

I like it ok. This rifle isn't the most accurate to begin with but in a 22" barrel Win70 Featherweight it does seem to be fast. After a little bit of research I've decide that RL26 (if I can find some) is my next powder to try in a handful of rifles.
