Powder question H4831 for .270
My wife had picked up a can of powder for me but instead of the IMR4831 that I normally use she came home with H4831. I have been using the Speer Manual for reloading in my .270 along with using CCI 200 primers and 130gr Speer Spitzer BTs. However my Speer manual (#13)does not list any loads using H4831 and 130 gr bullets. My question is will it be acceptable to use the H4831 with CCI 200 primers and the Speer 130 gr spitzers??? If it makes a difference I will be using new Winchester brass.
I looked through the archives and it appears that it would be ok but Im not sure what starting load to use. Any suggestions are appreciated. Thanks. Mike

I`ve burnt lb`s of it in my 270. Exact data is available on Hodgdon web site but, 58-60 gr usually is a max load from what I`ve seen others claim and my own use.

Hi Joe thanks for the reply. Im here in Bay City. Either my wife or I will stop in at Williams in Davison to pick up a few reloading supplies whenever we travel through that area. I have also started reloading for a 30-06 Weatherby Accumark that I purchased last winter. Fun stuff. : )

Mike, you'll be just fine with the H4831. It is probably one of the top 3 powders of all time for the 270. For many it is the #1 choice.

You can probably easily start with 56.5 grains and work up. I currently load 57.0 gr for my brother's rifle with the 130 Btip. I remember years ago loading 61.0 gr for my old factory Ruger 270/130 Speer in the early 90s.

H4831 in a .270 is peas and carrots. Your
wife did you a favor.

60 grains with a 130gr. Not high pressure
but good speed and accurate.

H4831 is slower burning that IMR 4831, so you'll need a tad more of it for equal velocities and pressures. My 270 tops out at 58.5 grains of H4831 with a 130 grain bullet, but it digests less than most. 58 grains is a reasonable starting load, and with most guns you can work upward towards 60 grains.

For some 20 years I use H4831 in my Remington 700, .270 Win.
With the TSX 130 over 59.5 grains I got a velocity at 4 yards of about 3110, accuracy sub to half MOA; with the TTSX 130 over 60 grains speed is 3180, accuracy about equal.
Use the Audette method for load development and you will not be disappointed.
Nice day,

My Hodgdon #26 manual shows start load 55grs,60gr max for H-4831 and start load 55grs,58gr max for the IMR-4831.

58gr H4831 under a 130gr pill with a cci primer has been the ticket in 2 different rifles for me.

I have also had good luck with H4831. 59 grains and 59.5 grains under 130 grain BT. were the loads for the two different 270s I had. I Recently tried Rel. 19 under a Barnes 130 TSX in the new .270 and I am happy with the results. I got the same good accuracy and better velocity. DW

Well today I went to the range to test out a few rounds and here were my results with the H4831.

My first 3 shot group was with 58 grains and it measured .493" Velocities for the 3 shots were 2850, 2867, 2845.

My 2nd 3 shot group was with 58.5 grains and the group measured .776" and the velocities were 2879, 2859, 2848.

My 3rd 3 shot group was with 59 grains and the group opened up to 1.445" and the velocities were 2921, 2935, 2945.

I was using my Sig Arms SHR970. The weather was warm here today so I had a limited session. I am pleased with the results so far and need to shoot some more test groups with the 59 grains. Thanks for the tips guys. Mike

H-4831 and th 130g pills for the 270 is great. Just ask Jack O'Connor.

Since each rifle is different, just work up to the load that works best for your rifle and components. The Winchester brass seeems to me to be able to handle a few grains more as to capacity than some of the other manufacturers. I've had good luck with that combo and using charges above 59 grains as well.

max. loads will of course depend on your individual rifle, seating depth, etc. starting loads should be about 54 grs. max. loads should be somewhere around 57 to 60 grs. this is a great .270 powder normally just very slightly slower burning than imr 4831.


velocity is like a new car, always losing value.
BC is like diamonds, holding value forever.
