.270win what powder next?

H4831sc gets my vote. It may be my old tang safety Ruger M77 that makes it easy, but I have a sub moa load with for every projectile I've loaded with it. 130 gr NABs, 140 gr NAB's and TBT's, 150 gr HIL's, 160 gr NP's and KKSP's.

I have other powders (RL22 and Varget), but other rifles like those specifically, so H4831sc for the .270 it is.

Used IMR4350 with Sierra 140 Gr Ballistic tips outta my Rem.700 Mountain rifle contour back in the day.
3 Shots covered by a quarter at 100 with little to no cool down between shots.
Why change ?
Why not buy another rifle and develop something as successful as the 270 ?
Besides a Canadian Gun Store will thank you for buying a new to you rifle ;)

The only reason I'm thinking of changing is that I've been loading reduced loads for my 10 year old to see if he can shoot my rifle. He's showing that yes he can shoot it so now I get a new rifle! woop woop. I'm sticking with .270 because I was gifted hundreds of bullets from a friend who passed away so I want to use it up.

h4831 is the starting point, it's a slower powder than your 4350. Smaller projectile should use a faster powder.

If it would be me, I would look in reloading manuals first. Check a burn chart for something....available....in the manual....slightly faster than imr 4350. If you need to experiment .......thats a good.thing.

I hear you, I guess I've never spent any time learning what each powder is. You are right, experimenting is good. Currently trying to work up a tight 110 gr hollow point load to get my son out for wolves. SHould be fun

No, as bore diameter decreases, for the same case capacity, you use a slower powder. 9.3/35 whelen requires a faster powder than .30/06, which uses a faster powder than .270, and so on.

SO, I should find a powder with a slower "burn rate" than IMR4350 if I'm loading 110 gr bullets? Smaller than my pet load is 52.5 gr of IMR 4350 behind a 150 gr speer boattail.
 
Another vote for h4831sc, I had a little more accuracy with RL22 but at near max and with warmer weather load was to hot. Still great groups with h4831( half inch 3 shot groups at 100m) without having to constantly change with the temperature.
 
H4895 can let you run reduced loads for the youngsters, I have a load that shoots decent with 110 vmax's.
 
Small game load from Ken Waters "Pet Loads" 110gr/21gr-4198/1772 fps. 3.30" OAL under an 1" @ 100 yards. Doesn't specify which version of powder Hodgdon or IMR but being a reduced load to begin with shouldn't matter.
 
If you can set up a position where they are standing, don't reduce the load. Let them flex with the shot. My gun kicks less with the 130 than it did with the 110's. A set of shooting sticks or what I call a parrot perch at a comfortable height for the gun rest, that will allow for them to flex with the shot.
The parrot perch is 2 posts with a post nailed to the top 55" high for me. Think shooting blind.
 
I have been loading Sierra 110 gr spitzers with 47gr of 4064 and have had fantastic success with that particular load (Sub MOA). Although for anything heavier like a 130 or 150 I would load with something slower burning like a H4831.
 
I'm also a fan of H4831 and 130 grain for my .270. I actually download to 54 grains which slows things down to around 2750 (guestimate based on the 1-grain velocity factor in the Lee manual) In my rifle it results in a soft-shooting round that still has the energy to drop red deer at sensible ranges (for me!), but minimises carcass damage on the smaller roe deer that tend to be my usual quarry. Most of my shooting is sub-200 yard so I don't need the extra legs of a fuller load :)

Great way for using the 270. I do 55 grains H4831 with 130 Partition. This is my load for the woods. One can achieve the same velocity with IMR 4064 at around 47 grains, and lower pressure.

It's a sweet load, for certain. I actually came up with it as I wanted to use my .270 as a Jack of all Trades. I now have a Husky .308 though, which I plan on using as my dedicated woodland rifle, so the .270 can get some velocity back now I think. I had two accuracy nodes with H4831, one at 54 grains and the other at 59. Anything else gave me groups that looked as though they were the result of a bayonet charge.

That's a really interesting point about the IMR4064. We're going to be really limited for certain powders very soon, as a lot are no longer acceptable for import to Europe and the UK due to our idiotic REACH compliance issues

An outstanding load with the 270 is a Partition 150 loaded to around 2950-3000 fps. It has a mpbr of around 300 yards and can be used from 0 to 400 yards, and up to moose.

That sounds like a hammer, right enough! Our biggest deer are Reds, with a big stag weighing in at around 400lbs. Not a patch on your big moose. The .270 has been used on reds here for a loooong, with the classic 130 being the 'standard' bullet. With mine, I zero 2" high at 100 yards, to also give me a MPBR of 300 yards (ish). I think it would probably have lost sufficient energy by then to make it a very marginal load on reds at that range, and I have to confess my load is a bit of a compromise to minimise the carcass damage on the smaller species. Now that the REACH compliance has banned my beloved H4831 from being imported to Europe and the UK, I'll need to find an alternative load. I recently picked up a .308 to use as a woodland rifle, so this means I can restore the performance of the .270

You can try RL 22. It is great with the 270. 58 grain is a perfect load for longer range and 130 grain.
