Hi members
Interested to hear your experiences with this weight in .270. I have tried SST's in my sako and found them to have outstanding accuracy. Muzzle Velocity is pretty glacial for a .270, at around 2600fps, at book max with 2209. I will be trying it over book max, as I am getting zero pressure signs on a hot sunny day.
Interested in MV and accuracy with powders.
Thanks
The heavier projectiles in 270 (ie 150gns) go better with a slower powder. I used Vit N560 and ADI2213sc with all my 140-161gn projectiles and from memory was getting about 2900fps with the 150gn Speer Grand Slam. Very effective bullet but not really a long range option.
Yep, 150 SSTs in my 75 Finnlight with ADI2213sc are slow but accurate. Slower speed means no blowup a though.
150Bergers-awesome!
Roger that. If I could get them up to 2700 with the same accuracy I'd call it done.

That's a fairly continuous string of 13 shots up top.
What rifle? Barrel length?
It's a Sako 75 with a 22" barrel I think. What thye come with.
Ok. I was shooting a 24" barrel. Probably good for an extra 100fps or so.
son shot big red hind at really really faaarked up angle with 150 grn partition...she must have been playing twister or something at moment he fired. 200ish yards over book max with AR2213sc 20 and a bit" barrel
went through back hock,unzipped puku then into chest cavity faarking both lungs before breaking one shoulder and resting under skin, projectile looks like the brochure's and the hind went down within 50 yards.
always been a 130grn fan myself but that really impressed me.
The 150gn Partitions are sledgehammers.
I've run 150gr Berger VLD's in my Rem700 270WSM for a few years. MV 3100fps out of a factory 22" barrel. Puts holes in holes and makes deer proper dead from a long way away, up close too.
71gr of Retumbo
Getting 2950fps out of a 22"(Wby Mk5 Ultralight, kicks like a mule!) and 3000fps out of a 24"(Sako Finnbear, nice to shoot) with the 150SST, tight grouping and good clean killer up close and out far, 55gn 2209 in both.Quote:

ADI2217 or IMR7828 with a mag primer gets then going fast too.
I've got 101x 150gr VLD's for sale.
150gr Nosler LRAB with 2213sc @ 2760fps in a Sako 75 Finnlight. Will try the 150gr SST next time when I run out of Noslers.
So 2213sc might be the go?
150gr LRAB in front of 2209, doing 2840fps from 20" T3, shoots around 1/2" , packs a punch all the way out past 850yds. Havnt tried them on an animal out that far but have them dialling reliably and shot a buck chamois front-on last week at 250yds, entered the chest and liquified the heart and one side of the lungs, left a pretty decent exit out through a rib, very impressive projectile
What charge weight?Quote:

what charge weight are you using @Beavis ? to achieve 2600 ?
49gr. ADI book max. Have tried 2213sc and again struggled to get 2700 and accuracy went poos. Have tried some 130gr sst's today, both 2209 and 2213. Got them to 2900 with both. At this point I'm probably better off going with them. On strelok they are equal in wind drift to the 150's and pack more punch and impact velocity.
i got sum norma oryx 150gr really good on big reds,samba
sold my 270wsm so can,t use them anymore if anybody wants to buy ?
