Home Forums Reloading Big Game Rifles Best powder for the 270 Win??

I have done a good bit of reloading but the 270 Win is relatively new to me. Which would be the best powder to start with? I have thought of using the Barnes 130 gr TSX but the more I use Speer bullets the more I like them (would be using the 130 gr BTSP).

Also has anyone used RL-15 in the 270 and had good results?

H-4831, any of the 4350s, RL 19 or 22, even H-1000 and IMR-7828.

MagPro gives top velocities per their data with a 150 gr bullet, but I haven't tried it.

Would think that RL15 is not well matched to a 130 gr bullet in the 270. Calif Hunter provides a pretty good list. I am having very good luck with the short cut version of H4831, top notch velocity & great accuracy.
The Speer bullets will do just fine, tho' the TSX is an impressively accurate bullet in both of my 270's.

You do know the BTSP Speers are not Hot Cores and are pretty soft, right?

With 130 grain bullets 55 gr. IMR4350 and 60 gr. H4831 are classics. Of course work up carefully, you know the drill.

WyoJoe-a best doesn't exist IMO but there are some really good choices that continually float to the top of the heap. R22, H4831 and either IMR4350 or H4350.

As for the question about R15 I'd use it with the 90's-110's but most likely not for the 130's.

Good luck to ya

H4831 and RL 22 are also tops in my book.

H4831 (and SC) or H4350 will get you where you want to be. R22 works but took me longer to get a good load. There is a lot of collective experience to draw from with the 4831 and 4350 to get you up and running quick.

H4831 is the classic load with close to 60 grains for 130s but I had better results with 54gr of imr 4350. I think that is the charge but better check it. I also remember maybe Mule Deer writing that that was a load winchester used in their factory loads for quite some time.

55.5 of H4831 and a Sierra 150 BTSP was 2700fps and shot way less than an inch .

H4831SC is the first powder I grab for .270. Never felt the need to look elsewhere.

Looks like H4831 is where I start.

Joe:
I use 57 gr. of Rldr-22 in my .270 Win. but this is with 150 Partitions. Afraid I don't use 130's in it. Maybe this'll give you something to think about tho.

Ramshot hunter also works good.

I'm running 140 gr AB's over 57.5 gr of 4831

for 130 grain bullets H4831SC or RL22. Near Max on RL22 59.5 grains works best for my gun, 57 IIRC on the H4831SC. I see RL15 as more of a .308 winchester powder.

H4831 has always given me the best accuracy from 270 Wins. R22 has given the best velocity and descent accuracy as well.

Good Luck

I use them in my .243 (85 gr for deer & prairie dogs) & my .375 (270 gr for deer & antelope). I am quite pleased with them so far.

Good deal. My father popped a lot of deer with the .308" Speer boat tails, 150 grains from a 30-06 and 165 grains from a 300 Winchester. He pretty much used those and their Sierra counterparts for a long stretch and never needed more than one per deer.

That was my last antelope. Took her in the chest as she was looking at me from about 300 yards. Hit her with the 270 gr in the .375. Bang, flop!

I think H4831 is generally considered "The .270 Powder". R-22, R-19, N160, N165, H4350, etc, etc.

Several powders work well with the 270 winchester. H4831 is certainly the "classic" powder but I've been having great luck with RL-22 and prefer it to several others I've tried............................DJ
