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

Hanco is resurrecting some old threads!

That's OK some missed it the first time maybe.

A whole pile work....from 4064 to RL25 and similar. The new slow burners raise new possibilities.

Recently I have used H 4831, 7828,and RL22...mostly because I have a lot of all three to burn through.

I like RL-22 & Norma MRP best & they are essentially interchangeable, but RL-19, 4350, 4831, 7828 & WW-780 are all very good too.

I wouldn't feel bad having to use any of them.

MM

Hunter meters really well and works for me with the 130gr TTSX. H4831sc works well with the 140gr Accubond.

Magnum

Can't go wrong with H4831...it's worked well many times. Recently RL-17 made 130s sing in my 270. IMR4451, RL23, and RL-16 all look quite promising with 130s, but I haven't been able to play with these yet.

Frankly, the 270 is generally not powder fussy.

I don't own a 270, but several friends do and I load for them.

Every time one of them waik in with a new one, I start necking down GI brass, prime them with CCI 250's, pick an accurate 130 gr boat tail, and add H4831 until I see 3100 on the Chrony. somewhere between 57 and 61 gr of powder.

Yes, I should watch the dates on posts a bit better. But then the 270 and 4831 is ageless, even if it is gay.

Pretty much the only powder I have ever tried is H4831sc.


IMR 4451 sounds like an interesting choice.

I haven't tried any of the newer powders, but 2925 fps with RL-22 and a 150 gr partition landing consistently under an inch is hard for me to wanna fudd with!

Gunner I use Rl22 and H4831 and the animals keep falling down.....

I still run H4831 in my one remaining .270, but have run Hunter and Magnum in some with fine results. My wife used Hunter with 140 TSX's when she still hunted with a NULA in .270 Winchester and it worked great, but then she switched to a NULA in .257 Roberts (it also works great with Hunter and the 100 TTSX).

Gave up on RL-22 for my own hunting here in Montana years ago because it performed so poorly in cold weather, but for hunters who don't have to deal with temperature extremes it's outstanding.

Tried IMR7977 because Hodgdon's data shows it producing somewhat more velocity with 150's in the .270, but it didn't in my rifle, and the maximum load COMPLETELY filled the case.

Am gonna try RL-26 next for the same reason, and see if it beats H4831....

Mule Deer please keep us posted on the R-26 results. I just started working with R-26 and the 140 Hornaday BTSP. Looks promising so far. I stopped at 61 grains and right at 3100 fps in a 24" barrel. If it proves to be accurate it should be a good all around deer load.

Hard to argue with H4831SC in the few I have shot. Out of that and have IMR4451 on hand in quantity. May try it with some 130 partitions. Anyone else used IMR4451 yet?

Hard, and staying down too. much to the chagrin of some campfire members, I love my 270's, they are some hard killing sob's.

I'm too old to change - H4831SC in 8# kegs - for the duration. It minimizes "powder roulette" in these times of sporadic shortages and who knows what in the future.

There is indeed A LOT to be said for simplified simplicity in uncertain times BW.


In any other case, the extra 50 fps loss or so will never be questioned by any game animal so hit, I don't think they're gonna care!

Anyone tried the new IMR 4451? I just loaded a few, but haven't had time to try them out at the range.....

Initial work with the 140 gr Sierra HPBT gave decent results but I haven't done too much experimenting with it since. I don't really want to load bullets lighter than 140 gr but I bet it works great with lighter bullets.

The Hogden site shows loads from 52.6gr to 56.0gr with IMR4451 and 130gr bullets. I loaded from 54.0 to 56.0 in .5gr increments with 3.30 OAL and 130gr TTSX and shot them with a M70FWT. MV is 15ft from the muzzle.
54.0 3005fps 1 1/2 INCH GROUP
54.5 3019fps 2"
55.0 3041fps 1 5/8"
55.5 3070fps 1 3/8" 5Sd
56.0 3075fps 2 1/4"
Not quite as good as the old H4831 in this rifle but tweaking things around 55.5gr would probably yield some accuracy improvements. The new powder didn't meter significantly better than 4831 but trickling every load is not a big deal as much as the 270 is shot.
I wouldn't think twice about loading up 55.5gr and going hunting.

H4831 for the win.

Put a fork in it.

H-4831 is darn good with 130's and 150's in my accumark. VV N-560 is fantastic with 130's

Good luck and shoot straight
