yeah ,thanks for the suggestion , but i previously owned one . sako 85 grizzly , used it for group one and did a trip up north . nice rifle except it used to fling cases into the scope turret and back into the action .turned the loopy scope (2.5-8x36) 90 degrees left , that solved it . the calibre itself doesn't lend itself to my secondary purpose of pig/deer hunting as the projectiles are too stout for this size game in my part of oz . tried 270 speers and 250 nosler bt's , 308 works better cause of better projectile expansion. on game the size of feral donkeys , horses and bigger the 9.3 was great . it'd be a good thing for sambar i reckon .
35 whelen was my original choice , but i think the 338-06 is a little cheaper to run and i like the case better cause it's got a little more shoulder . got my die set yesterday , going to do some dummy rounds up this weekend and have a look at COL and where the projectiles sit in the neck . ideally i'll be looking at boat tails with the bearing surface just above the start of the neck to avoid any donut issues with resizing 30-06 cases . had issues with a 8x60s brno 21 a few years back with resized cases . i want to thoroughly check things out before i commit to buying a barrel

Where did u get the idea the 338 would be cheaper to run ??

after a quick scan of supplies at my local , projectiles are marginally cheaper , little less powder for mild accuracy loads according to load data i've looked at , 30-06 brass is not as expensive for resizing compared to 9.3x62 head stamped brass . 35 whelen is comparable to 338-06 cost wise i guess, there's a little more choice in 338 with the projectile weights i want to use . there's probably not that much in it cost wise generally speaking , but every little bit helps these days.

Rich, what's the go with your Sako 85 bouncing cases back in off the scope? And the scope you mention is a beautiful streamlined scope too.
I have heard it before, but no matter how I muck around with the ones we have ( a 223 varmint XS action, two 308's M action and a 300WM L action) I cannot see how that can happen.
The cases come out at what looks like at 3 o'clock, which clears the absolutely lowest scope mountings I can get. I won't tolerate high mounts.

Scopes are 4.5-14x50 VX3i on 223, and three 3.5-10x40 VX3i on the others. Leupold Sako ringmounts. Would this make a difference?

The actions on the 85's are like a Mauser in that the harder you pull the bolt rearward, the faster and further the case will be flung out. If I move the bolt back slowly, the case will click off the bolt face and then sit in the action to be plucked out. But that's the design, if you don't want cases flying into the grass.

The 90's I have, have now twin plunger extractors on the bolt face borrowed from the TRG rifles instead of the mechanical blade ejector of the 85. The way they pelt the cases out even with a lethargic bolt throw is extremely positive but not good if you are after keeping them in the bush.
But Sako have deleted the semi-controlled feed of the 85 which I actually think was a big positive to have kept.
That change to twin plungers has been said to have been done because some people seem to always have been able to have malfunctions with the blade ejector, where most others can't make it happen if they try. I don't get why.

Ive only mention the 358Win which I find to be a superior package

308W brass necked up, projectile plentiful from 180-250gr, uses less powder and came be built on a lighter shorter action with a short efficient barrel

I's sure the 338-06 will work fine

hey mate , i'll relate as much as i can remember regarding the issues i had with my 85's . i had two long actions , my 9.3x62 ,and a 270 laminate stainless i bought brand new . both flung the cases up on a 45-50 degree angle and with a scope like the 2.5-8 the turret was directly over the top of where the front of the case wanted to go when ejected and would hit and rebound back into the action . 3-9 scopes worked as the turret was in a different position. i found on a american forum a poster who got to the bottom of this issue . when sako went to a 3 lug bolt they had to move the extractor to a higher position on the bolt face because of the extra bolt lug , resulting in a higher ejection angle with the blade ejector in the original position . the other thing was the extractor to bolt face clearance was set too loose for the rim thickness of some cases . he listed various cases/calibres and their rim thickness . i put a 308 case in the bolt face of my 9.3 (308 win has the thickest case rim ) and it ejected much better at a lower angle . so having a custom extractor to sit closer to the bolt face to hold the case tighter seemed a solution. this problem is well documented on the web . give jim kent at buffalo gunsmithing a call , he's had to do work on various 85's to resolve this issue . i researched this thoroughly, speed of bolt operation and whatever else i could think of . the fit, finish, accuracy of my sako's was excellent , but feeding or ejection issues i won't tolerate . i know a fella with a 500 jefferys , who once it was pointed out to him , brass on the bottom of the scope turret, fitted a red dot on his . this issue doesn't seem to affect all sako 85's ,
the 90 series with it's twin button ejectors was supposed to solve ejection issues.

i had a 358 win , great little cartridge and extremely accurate . it won't get me 2900 ft lbs of muzzle energy with a 225gn bullet unfortunately . that's the minimum level for group 1 big game . min cal is 333 . 225gn game kings flatten anything in 358win , and 180gn xtp's make paddock pizza out of smaller ferals
i made up a dummy 338-06 round this afternoon with a box of 225gn speer boat tails . the bearing surface sits above the potential problem area of the neck, from the old 30-06 shoulder/neck possibly giving donut issues . this is looking promising . another week or two and i'll have enough coin to order a barrel

Big rich my current thermally load is 180gr OEP at 2750fps that's 3023 ftlb of energy using 2219

I am interested in how the build goes keep on posting the 338-06 is not a round I have any experience with.
I have messed with 338 win mag it gets used a lot here for elk and bears and shoots rather flat.

yeah the 338 win mag is highly regarded up northern australia as a "do all" round . when i was up there i asked people's opinions on the one gun to do it all and the 338 win mag was the most common response . the advantage of the 338-06 is it can be built on a standard long action with no mods and brass from 30-06 is easy . going by load data it's 100 -150 fps slower than the win mag generally and is extremely efficient with regards to the amount of powder it burns . looking at chuck hawks expanded rifle ballistic chart, it acts like a 7x57 . moderate velocity, but with a 225gn pill it cleaves to it's energy out a lot further than some other medium bores . this probably doesn't matter to most that hunt out to 200 yards, but i like to have any advantage
a lot of american hunters seem to like it for whitetail to moose and bears , and it has very good penetration ability's apparently . the win mag is superior in energy and ballistics , but with a bit more recoil too . for my intended dual purpose , comp/hunting, i want to keep recoil to within reason . i'll try to keep the posts up, but it'll be a while before the gun is built . ordering a barrel within the next week .
