As I understand it H4831 and RL22 are the go to powders for the 270W/130gr load...

But anyone using IMR4350 with great results, MV and accuracy-wise?

Wanting to do some load development soon for a couple hunting rifles...

Thanks!

Try it I think you will like it.
One of my 270 Win. prefers H-4350 and IMR 4350 for 130 grainers. I am getting upper-3200 fps. plus with my load and the old Winchester SilverTips. With 130 gr. Nosler Partitions it will deliver upper 3100s and into low 3200 fps. Accuracy is superb with the Partitions - under 1 MOA at 200 yards. Generally around 1-1/2", and under, center to center groups at 200 yards. And I don't mean one time in a shooting session, I'm saying three-fourths of the time.
When the groups get to 2", it's time to clean the barrel.

I just loaded up some AA-4350 last week for my other 270 Win. (with after market barrel) and the accuracy was good. Did not have time to chonograph anything yet. This particular keg of AA powder is pretty slow. I estimate it in the range of RL-19 as I am using just about the same amount of the AA-4350 as I did with the RL-19 to get the same results. I'm using 140 grainers in that gun. I will have to go back and look at my notes. I don't think I've ever tried IMR-4350 or H-4350 in this particular rifle.

That is partially true. IMR and H4350 are also both go to powders for the 270. Show me a guy with a 270 and a 4831 with a great load and I'll show you one with 4350. I was taught that 4831 IS the go to powder for the 270, but in my opinion, there are 3: 4350, 4831, Re19.

I've NEVER had a problem finding a great load with any of those 3.

My 150 VLD load is pushed by IMR4350 and a magnum primer.

It shoots great in mine. However, I'm shooting 140 grain Accubonds ahead of 52.5 grains of IMR 4350. I get 4 shot .7" groups at 100 yds. I use Winchester Standard LR primers.

54.5 grains of IMR 4350 is my go to load for 130 grain bullets.

Now, I'm honestly excited to try this powder thanks to you guys!

I appreciate the help

Great performance with acc4350 and 130 and 150 grain bullets, but than performance levels good with the 4831s, DP85 and Dp86. Personally the individual rifle is the biggest factor. roger

Good luck LB. I'll truly be shocked if you can't find a shooter load with 4350.

Just so you know, David Tubbs said on his Sierra loading videos that if he had to use only 2 powders for all his shooting, they'd be IMR4350 and IMR4064.

To date, I'm still scratching my head why more reloaders don't use IMR4064 in a lot of applications for hunting. It is an excellent powder for accuracy.

55.0grs of IMR-4350 is what mine likes best with 130gr bullets.

For me the "go to powder" is IMR 8208 XBR.

LB, here's that 150 VLD target at 100 yards with IMR4350:



and 200 yards:

Doc-

Ya got a load there buddy

H4350 is a good choice, especially in shorter barrels.

I have been shooting the 270 Winchester since 1969, most of my loading has been with 4350. Now I load 56/4350/130 Nosler Ballistic Tip/ 3050-3100fps. Excellent accuracy and I have killed deer, elk, and a host of other critters. I have been very happy with 4350.

My Ruger/Hart 270 uses H4350 with the 110 TSX. My brother's uses IMR4350.

I agree. I was pleasantly surprised considering it was the second hand load try. The other was with H4831SC and it wasn't shabby either. Sort of to my surprise, that 150VLD works very well on whitetails and coyotes.

Haven't clocked it yet but as you can see it is 1/4" high at 100 and 1/2" low at 200. I CAN LIVE WITH THAT!!

IMR 4350 is what i use.. and 130 gr sierra spbt

Thanks Gents I appreciate the replies

Hey LB

IME IMR4350 can be very accurate



but has a very narrow window. IOW a slight variance one way or the other can reduce accuracy drastically where with a slower powder the window of accuracy is a little wider.

Nice shootin Woods...as always!

I push my 130 TSX with 57.0 Reloder 19. No clue about speed though. Need to chrony them.

Hey Woods-

Thanks for the comment about that window in regards to using a slower powder...

But I just picked up 8 lbs of IMR 4350 and due to a tight budget will be trying to develop loads for a bunch of deer hunting rifles I have...

270W/130gr
6.5x55/120gr [(2) Modern actions]
25-06/117gr
30-06/150g
7RM/139gr

I'm HOPING I can get some accurate hunting loads
using IMR 4350 for them all...

If you or anyone can comment I would be grateful

LB, if you are looking for one very flexable powder, IMR4350 certainly fits the bill. You could add a .243 Win, and a .338 WM to your collction and still not need another powder.

Brother, That's just what I NEEDED to hear!

I forgot to include my wife's 243/100gr rifle...

BUT, being able to load an ACCEPTABLE running powder like IMR 4350 in all of these is my goal for hunting accuracy!

I'm not a reloader who is trying to eek out high velocity from my cartridges but just would like to roll my own to get lots of bullets on the cheap customized somewhat for my rifles!

I'm very pleased with your comment!

All I desire is MOA and with a good hunting bullet for the task...and let'r'rip....hehehehe

Thank ya much

Aloha!

I used IMR-4350 in my .270 Win, .243, 7X57m/m &,.30-06, with various bullet weights with excellent results & accuracy.

Thank you for commenting

I love imr 4350 and the 270. 54grs imr 4350, WW brass, WLR primer, nosler 130gr partiion. Neck shot my deer last year with this load at 150yds. (it was laying down looking back at me)
My accuracy load is 140gr ballistic tip, 52gr imr 4350, ww brass, wlr primer.
You can't go wrong with imr4350 in the 270

Just pole axed a 170 pound whitetail doe in KY this morning 20 min into my hunt with my 270/IMR4350/150 Berger VLD load.

Put her down at 289 yards. Pick up the meat tomorrow afternoon from the butcher.

IMR4350 works very well in the 300 WM also. I have a real tack driver load in my 7mag with a 150 Swift Scirocco and IMR4350. It is another very small cluster at 100 and 200 yards with Win brass, and Fed 215M primers. No clue on speed but FWIW, impact is 1/2" high at 100 and dead on at 200.
