Home Forums Reloading Big Game Rifles What powder for 270 win, 130 gr bulets

Depends on what range of temperatures you hunt in.

Several of the powders mentioned so far result in different velocities at widely varying temps--which can affect not only accuracy but point of impact. But if you hunt in temps around freezing to 80 or so, just about any modern rifle powder will be pretty consistent.

If your hunting temps vary more, in my experience H4831 or H4831SC usually results in the finest accuracy--and plenty of velocity.

I've always used H4831 in my 270 with 130 bullets. It always gave me the most consistent velocities and accuracy of the short list of powders I tried. Once I find something that works that well, I seldom experiment much further...

4831 SC for heavier bullets... 140 to 160 grains...

4064 or RL 15 for 120 to 140 grain Bullets...

I like the 140 grain Ballistic Tip and 4064 for deer hunting the most...

second favorite load for heavier animals... 160 SMP Partition, stiff load of H 4831SC...and crimped...

After trying for first time last season I would try RL16 1st these days. Higher velocity with same accuracy and supposedly temp stable like H4831. If neither of those then rl17, rl19, rl22, hunter, magpro, imr-4831 have all worked great for me with 130s over the years in one load or another.

H4831 followed by RL26.

I'm surprised no-one mentioned RL22.

RL26 works for me.

I wish I could find R26, my 6.5-06 loves that powder as well.[/quote]

I’ve been a H4831 kinda guy with all my 270’s and in 2019 found one of mine (Colt Sauer) loved 26 with 140 grain BT’s or Sierra Gamechangers. This makes no sense to me. It apparently makes no sense to Alliant either, as they only publish 150 grain data for the 270. Too slow burning for this application obviously. Around 61 or so grains was listed for several makes of 150 grain bullets. I broke a cardinal rule of reloading and said to heck with it and assumed 60.0 grains for140’s might work. My rifle loved it. 3025 fps, nice little round groups.

Yaddio,

RL-22 can produce some spectacular accuracy and velocities with 130s (and other bullet weights) in the .270. But it's also one of themost temperature-sensitive rifle powders I've ever tested at various temperatures from zero to 100 degrees Fahrenheit--which can result in widely varying accuracy and point-of-impact
Yaddio,

RL-22 can produce some spectacular accuracy and velocities with 130s (and other bullet weights) in the .270. But it's also one of the most temperature-sensitive rifle powders I've ever tested at various temperatures from zero to 100 degrees Fahrenheit--which can result in widely varying accuracy and point-of-impact. Which is why I haven't used RL-22 for handloading the .270 in over 20 years.

However, have found RL-19 (anybody find any lately?) VERY accurate with 130s, and less temperature sensitive.

H4895 is a great powder for reduced-starting loads in many cartridges. The results are reduced recoil, good accuracy and usually more than enough velocity to kill deer for quite a ways.

One thing these reduced loads and even the smaller cartridges (6.5G for example) have shown me, is that by and large, any velocity much over 22-2300fps in small bore cartridges is simply icing on the cake. Yes, you have better downrange performance and trajectory at extended ranges with a standard load, but something like a Grendel or a reduced/starting load 270 has the power to be effective past 200, 300, even up to 400 yards.

Aside from those benefits I mentioned, they also help conserve powder which is a good tool to have in the toolbox when shortages take take their toll.

I found N560 to be extremely accurate in my 270 with 130's and 110's. H4831 is no slouch either but I found it more accurate with 150's. The 150 NPT and H4831SC in my rifle will shoot into 1 big hole and I would not hesitate to shoot any game animal in the lower 48 with that combination.

Good luck and shoot straight y'all

H4841sc

Thanks MD. Here on the Central Coast of California we don't have much temperature variation, but yea, I get it. Sierra had RL22 as their accuracy load in an older loading manual for 130s and I think ? for 150s too. I think Nosler at one point gave it the nod too. Dang were those GKs accurate with that combo. When I had to switch over to copper bullets I didn't see RL22 listed anywhere for the 130 TSXs. I called Barnes and asked if they had any data for 130 TSX and RL22. The guy on the other end of the phone said that RL22 was too slow for that combo. I figured WTH and worked up to a load anyway of 58 grains and it shot MOA in my M70, (RL22 was listed with almost every other manual for 130s). I've since switched to H4831 and loaded enough 130 TTSXs to keep me in business for a while. I did try RL19 with the 130 TSX, but contrary to others results it didn't shoot well. I still have almost 2 lbs of RL19 left.
