Just wondering what this weight bullet goes like in the 270 is it worth trying out or better to stick with 130's
150s go great. Better than 130s for reds, thar imo.
140s are the bomb though. Great for anything.
The loads run in my 270.Quote:

You notice the relative velocity at 400, very similar, so you are looking for the weight and design that works best out there, heavy beats light once you get out a bit.
The 110 TTSX kills everything the 130's of any description can and is forgiving of awkward angles. Result inside 350 or so is dramatic:thumbsup:
The 130 TTSX kills fast out to around 300, forgives awkward angles but it is imperative to shoulder shoot at that distance on.
The 140 Accubond has good bc hits hard up close and still opens up well at intermediate distance.
The VLD (and 150 SST) is outstanding at distance without sacrificing the ability to hit hard up close. VLD bucks the wind the best.
I like the 150 VLD and 150 SST the best, they never fail to kill clean, heavy for calibre, they come apart inside without wrecking everthing else and carry plenty of energy way out, will still kill fast and clean out at 500. No experience with 270 beyond that distance.
The little 110 TTSX is f&*^King dynamite and you would not be undergunned on any animal in NZ inside 350, but becomes marginal past that for fast killing.
I don't use 130's as the lighter and heavier options are way better.
Plenty will disagree I'm sure.:P
I'm about to try some 140 Bergers on deer.
I use 130 TSX and ttsx in my .308 and they kill hard and fast.
One of the main reasons I asked is I might be getting some projectiles that are surplus to the owners requirements and the ones I actually want to boost my current stock of sierra gameking 130 grain there is also a part packet of speer 150gr boat tails that I was thinking about loading up just to see if they would be accurate in my remmy 700 and if it was the case then I would be tempted to actually change over to them at a later stage but I would say that I may have to waitill i can get a slower burning powder as I feel that the 2209 that i currently use may be a bit to fast in burn rate for the 150's
This forum is bloody great. I was going to ask the same question yesterday. I have a t3 with a 20" barrel and a hardy can on it and have run 130s with good results. But the extra power and higher BC of the heavier bullets have got me thinking. Might have to give them a try.
BTW great info there 257weatherby. :thumbsup:
never hurts to try :D just looked up the bc of those speer bullets and bugger me they have a bc of .489 and an sd of .279Quote:

2209 is definitely not to fast for 150s. I've been running 150gr Nosler partitions for about a year now in combination with 2209 and it's never missed a beat. I'm getting 2850fps out of a 22" barrel - this is a mild load but still quite a bit over book max so I think my barrel is quite a slow one but I'm not too fussed on velocity and 2850 still quite good for a 150gr out of a .270. Also when you go 150gr - you'll never go back. Maybe to 140's but not to 130's :D
Thanks for that info @Grunta I had a look at the load data on the nosler site last night and found that their accuracy powder for the 270win tested in a 24 inch barrel and their 150 grain bullets with an accuracy load of 52 grains(noslers max book load) of 2209, where as my speer manual which the data was tested with a 22 inch barrel maxes out at 51 grains with a MV of 2644fps which would put my remington in the ball park of 2750fps with its 24 inch barrel going by the chrony results I have from when I did some load testing up at muckos place the other week for my 130 grain sierra gamekings. So far all of my accuracy loads have been in the lower (just above min) to middle of the road charge weights. I care more about having decent accuracy over a full throttle load any day but it is a bonus when you do get some good speeds happening as well as accuracy as it gives you that little bit extra reach and knockdown performance.
How much velocity do you think you would lose per inch with that load? Im at 20", cut back from 22

2209 is fine for 270 Win, as you can see, a decent load of 2209 works fine and gives a small velocity gain over 2213sc at similar pressures- in this rifle driving 150 VLD's, a 22" barrel Wby Mk5 Ultralite, more velocity was easily gained using 2209, but recoil in a 6lb rifle becomes an issue. In a standard weight 270 with a 24" barrel it should be possible with a little care, to get an easy 3000fps, the bc gains in a 150 projectile easily negate the velocity gains loading the 130's. Weight is a non issue if all shots on animals are under 300, but why not set up with a projectile that will kill properly as far as you can shoot. The exception to that rule for me, is the 110 TTSX which will out penetrate even the mighty partition ( within the TTSX's correct operating range for ethical killing of game)
Am a commited 150 fan, but not in the bonded bullets like Accubond (140 is better) Interbond, Deep Curl and TTSX (not bonded but same drawback at long range)
(Stuck at home with nothing better to do:oh noes:)

Holy shit thats all over the paper! unless you were aiming at different points on the paper?Quote:

Heavy for calibre projectile, driven reasonably fast for calibre, in a 6lb rifle. The OP was questioning the viability of 150 in .270
Yeah, the red dot!!! :DQuote:

I use 150gn SSTs in my Sako .270.
56gn of 2213sc, Fed Match primers, neck sized RP brass, seated to fit mag.
Recorded the following groups at 100m when load testing.
0.41"
0.26"
0.42"
Seriously? ok: rifle zero is for 150 SST, which just happens to be going somewhere else, am assuming you adjust your zero to suit loads being tested, rather than the load you are currently using as that rifles hunting load?
I prefer to retain the zero used for hunting and do not really care where anything being tested goes, they could lad on the target next door for all I care- group potential has nothing to do with where they land, until the decision is made that that load is going to be "the one" at which point the zero is shifted to suit that load. Now, Do you have useful input re 150gn loads, powders, projectiles and terminal performance at varying ranges?
Barrel length and velocity?Quote:

I didn't know rifles could spit projectiles everywhere like your pic thats all
^ sigh...
Factory 75 Finnlight, so has the short 20 /8" barrel, so speed is sloooowwwwwwwwwwwwwww.Quote:

1- zero rifle to load used for hunting. This load is good for a consistant 3/4 and is zero for windage and three inches high at 110 yards. This is now the default load.That load is not on this target.
2- test load using a different projectile, use red dot as aim point, and see where they go, how fast and if they have group potential for further development. 2.5" high, 1.5" left- 3/4" group.
3- retest same load using different red dot to determine potential for consistency.2.5"high,1.25" left -sub 3/4" group.
4- test load on different powder charge, same projectile, use different red dot, to determine potential grouping accuracy and speed potential.2"high, 1.4" left- 1/4" group
5- retest this new load again, using a different red dot, to determine potential for consistency 1.75" high, 1.5" left- 1/2" group
6- remaing rounds fire using aim point between the top red dots.
Can you explain "spitting projectiles everywhere", I am confused by this. As a first up test for the Berger VDL in this rifle,, I considered it to be quite productive and worthy of development.
You could, potentially have a grasp of load development and shooting that I do not, you could become a tutorial master, and those of us that are inept in that field could be your students......
Would also appreciate your input to the thread subject, which was: 150gn projectiles and powders in .270.
1- Which 150gn .270 projectiles have you tested?
2- Which powders have you used in those tests?
3- What velocities have you achieved?
4- What overall grouping potential did you discover?
5- What terminal performance on game have you observed?.
MCCHE171, has a 20" barrel also, and is interested in 150gn performance in .270, you might have an observation or two?. In your short barrel, would you consider a light for calibre projectile like the 110 TTSX and a faster powder to gain back velocity?Quote:

My rifle seems to like 2213, both with 130gn and 150gn projectiles though.
Never got around trying Alliant R19/R22 or Viht N150/N160
I was using 130gn Gamekings for a while loaded at an atomic 2.5gn over max. Muzzle flash and recoil were amusing. :D
But decided to go for one mild loaded heavier projectile instead of a bush and dedicated longer range load.
Only load I wouldn't mind working up is the 150gn Long range Accubond, but too busy to get around to it.
I watched 3 goats fall over on the spot at 300m thats allQuote:

My .270 is a recent experiment as I had a 270 barrel on the bench after rebarelling another rifle, and then finally shooting out the barrel in my 2506ai gave the 270 barrel a new home, may yet pull it (or sell the rifle) and build a .25 Gibbs instead, have a really good 7mm Mag that shades the .270 by too big a margin.( and an 8.5 lb 7mm Mag doesn't have the amusing recoil that a 6 lb .270 loaded hot does!). Obviously, the .270 has a long and successful history but this one is my first, and I have found the 150's best for terminal performance in the limited game numbers shot with it .Quote:

Either bang flops or at best a 25m run before expiring (snap shot, hit bit back than normal).
I went off the 130gn Gamekings after a 325m shot on a red hind (top animal)

Thought I had only wounded her, so put another shot in and she dropped on the spot.
Went I got to her, both shots had gone through the engine room but had exited with minimal expansion.
My goal later on when I can afford it is to have another 7mm whether it be a 280 or 7mm WSM i have not made my mind up yet as I do not know if I want to rebarrel the remington later down the track and go 284 or buy one factory made in the first two 7mm calibers I mentioned and keep the 270 or what but that will be a while off yet.Quote:

The .280 has an advantage over the .284 for case development- you can go to 280ai or much faster, .280 Gibbs, with the Gibbs you will get 7mm Mag performance but on the 06 case, then you could keep the .270 barrel for if you wanted to go back.Quote:

That does seem very much on the slow side! if its accurate who caresQuote:

In combination with that and neck sizing brass I barely have to trim the cases.
Also slow loads with plastic tipped projectiles (SSTs in my case) seems to cut down on any blow ups on impact.
Yip, with that dogmatix i will keep my naughty greedy side under wraps :D
Not only brass life...one cannot undo any stress and strain put on the rifle with hot loads.Quote:
