Both sons shoot 270's and want to try to work up one load for both, the rifles are a remington 700 mtn rifle and a browning Abolt , both have 22" barrels .I have nosler 140 btips and 150 hornady sp on hand and imr 4831 , rl19 and h4350 powder but will try another powder if i need to . What is good velocity to shoot for ? thinking around 2850 to 2900 , but that is secondary to a good all purpose load .

2900 is easily achieved...

I'm behind the times.. I prefer 4064 with the 140s...

if I have to have maximum thump then I go with the 160 grain SMP Partition and a load of H 1000 behind it..

Best powder I,ve used is RL22, H4831SC, and IMR7828SSC.
I had best bullet results with 140gr Accubonds and
140gr Speer Game Kings. Still working on 150,s and powder.

Same goes for me except my experience is with 150's. Prob best accuracy goes to RL'22. Stuff some Partitions in there and go [bleep] 'um up!

I have owned a bunch of 270 Win's over the years and the most consistent accurate powder for the 270 is Hod or IMR 4350

My best groups were with the 150gr Sierra Gameking and IMR 4064, and I did try some 4350, but that was with 130gr pills.

Mine gets it's best grups with IMR4831,Fed 210m and Hornady 130s.
near max load

140 accubonds and H4831sc are magic in my .270. I've been very please with accubonds 130 in a 6.5X55 (H4350), 140 in 270 (H3831sc) and 165 in a .308 (Varget) all near max.

What I would do is load up five of the 140grs and 5 of the 150 grs of each powder about one gr under max and see what each likes. I wouldn't be surprised to see all of them work great. I'm not a fan of B-tips for hunting like mentioned I would go with a Nosler Accubond or a Hornady Interlock in a 140 gr. Good luck.

I use 140gr Accubonds over H-4831SC from a 22" tube. Whenever I push to reach 2900fps I start seeing pressure signs. Accuracy is exceptional with 58.0gr @ 2850fps. I'm going to try RL-22 next just because.

This load has replaced other great loads using 130gr SGK, 150gr GSlams, 140gr SSTs, and 140 Partitions.

57.0 grs of RL-22 and a 150 gr Partition in WW brass and lit with a CCI-250 primer run 2925 fps out of my old 24" barreled pre-64 270 WCF.

Sure lays a WHOOP on WT deer.

nosler #6 manual lists 58 grains h4831 ,its the most accurate load with that powder. It worked very well for me wih Hornady 140 btsp. Sub moa, 2900ish fps. Ramshot Hunter also very accurate at slightly less velocity

Same almost as Aceman. 56.0 gr H4831sc and a 140gr Hornady BTSP or Sierra 140gr Gameking. Both are around 2925fps and easily shoot sub moa. Good luck.

Same load as mine except I use Federal primers. Averaging 2930 fps out of my Pre-64 too.

IMR7828SSC gives as much speed as RL22, with 140gr Accubonds.
maybe a little more. Not sure about accuracy. Has any one
tried Magpro? Be carefull with 150gr bullets pressure goes
up Quick. Ask me how I Know. I was getting 3080fps with
59gr of RL22 and the 140gr Accubonds, per Barnes manuel,
and great accuracy.

Not recommending this load, as it's over current book maxes, but I used to load 59gr H4831 behind 140gr Hornady BTSPs. Was very accurate and averaged 3076fps from a 23" Hart barrel. Was extremely effective on all the deer and the one Elk I shot with it.

For this fall my load is with IMR 4350...and 140's both Serria and Hornady..I4350 has been great for 50 years...

I had real good groups with 52-53 grs of H4350 cci LRP primer and 140 gr. bullet coal @ 3.34" Good luck

Dang near same loads as mine. I use 56 grains of H-4831 with a 150 Partition and 56 grains of RL-22 with a 160 Partition. Both loads use F-215s and W-W cases.

Another vote for I4350.
Hornady book max with 140 btsp is extremely accurate in my 22" Abolt.

My Vanguard Sub MOA shoots bug hole groups with 150gr. Berger's and 58gr. of RL22.

Orion be careful with that load last week I had a learning
experience with that load and Federal cases. Didnt know they
held less volumne. Blew a primer with 58gr RL22 and 150gr Deep
Curl bullets.

H4831 and 150 grainers in the 270 are like Mother and Apple Pie.....

Having used a Oehler M48 Ballistics Lab on several 270's, I'll say when you hit 2900fps with a 22 inch bbl and 150gr bullets you are most likely at or above max pressure. Most of my 22 inch 270's top out at 2850-2885fps.

IMR4831 is temp sensitive with most loads, I rarely can get H or IMR 4350 to shoot well for me (bad powder karma I guess).

57-58 grains of H4831 will generally be max for 150's.

There are always exceptions: My latest rifle is a M700 SS Mountain Rifle built from parts. Regardless of powder, 2850fps is about max. 2900fps gives me a sticky bolt every time with 150's.

On the other hand, I have a 25 inch Douglas bbl 270 that shoots 150 NBT's over 3000fps, and that rifle and load stayed under max pressure on the Oehler M48.

My wife and I have owned around 12-15 .270's over the past 30 years. All shot well with H4841--and I've used all three versions, the original mil-surp, its replacement made in Scotland, and the present Australian-made H4831SC. Some of them would shoot slightly better with other powders, including IMR4350, H4350, RL-19, RL-22, IMR7828SSC, and Ramshot Hunter and Magnum, but I still tend to try H4831SC first. The one rifle that wouldn't shoot all that well with H4831 did best with RL-19 and Ramshot Magnum, so there are exceptions to every rule.

In a 22" barrel I tend to look at 2950 as maximum with 140's and 2900 with 150's, but there have been exceptions. Magnum and 7828SSC sometimes get a little more out of 150's, because they're a little slower than any of the other powders listed yet have small enough granules to fit in the case under a 150. In 24" barrels another 50 fps can be expected, and the one 26" barreled .270 I've owned got over 3000 with 150's.

Hard to beat the 150 Partition for game bigger than deer in my experience. The TSX's are also good, but the 150 tends to kill 'em quicker, and penetrates plenty.

Yes Sir, A+ on those 150 grain Nosler Partition for a 270 Win.

I,m trying to get the 150gr to shoot in my 270 Winchester.
I,m loading some 7828SSC and maybe some Ramshot Magnum if
I have any left from my 7mm Mag load work.

I like shooting 150 gr Speer, 55 gr IMR 4831. My Vanguard in 270 is very accurate. Randy

I have a Husqvarna model 9000 and it loves 140gr Hornady SST,BTSP's and Sierra 140gr Gamekings on top of 56.0gr of H4831SC. These loads consistently chrono 2900-2925 regardless of temp. And the groups are very tight. Best is 2.1 in at 300yds. That's nuts. I definately can't shoot that good while hunting. 140gr bullet is a great compromise in this cal as it shoots as flat as a 130gr but carries more energy. Goodluck.

150's IMR 7828ssc. Start at 55 gr load till you hit 2900 and stop!!

160 partitions 56 RL 22 goes 2800 in my rifle. Got this from Dober and it is a great load. Start at 54.5 and stop at 2800

130's H4831sc Start at 59 and increase til you hit 3100 then stop Or stop when you hit 61 gr.

140's Not for me. Use either 130 or 150.

All shot in 22.75" barrel

I like H4831 or RL22 with 150s. RL22 is typically about 50-75 fps faster with 150s for me, though H4831SC is labeled as temp insensitive. Given 22" barrel, 2850-2900 is about tops with 4831, and 29-2950 with RL22 with 150s in my opinion. Never tried it with 150s, but Magpro hums with 130s so expect would be top notch with 150s as well. For 140s, I still like H-4831 for 29-2950 fps and several other powders get to around 3000 fps like Hunter, RL22, RL19. If I had to pick one powder that I though would shoot best in just about any .270, it would be H-4831sc.

Lou

H4831sc and RL 22 shoot 140 Accubonds very well in my 24" Lilja, but my top RL load gives me 3050 while the top H4831 load is at 2950.

How much H4831SC you putting behind those 140s? I'll be loading some BTs of that weight later on and don't have a Nosler book.

Shootem-on the 140 and H4831 run 57 behind it and it'll perk like a dream!

Dober

Haven't had a perky dream since I was about 16, don't know if I'm still up for that . But I was thinking in the 57-58 range. #1 son will probably be taking it off to school as a backup to his .260. Thanks!

I run 58 grains of H4831 under a 140 Accubond or BT in a few rifles. Always seems to shoot well.

I was using 57.0 of H4831. Nosler lists 58.0 as max with a 140 BT
