Anyone shot the 60gr Partition

[Am88]

Thinking of giving them a go, not as a plinking round obviously. Going through the process of load development for my .222mag again, had a bit of a break due to 6 month old boy. But back into it again, now that I also have a family 4wd I will be setting the ute up more for shooting and fishing, it was pretty wife friendly before, not as much now. On top of the canopy will be a removable padded shooting bar. Primary use is deer, both out of my .222mag and wife's .223 when she can get back to it. Last thing I want is a neck wound where a bullet hasn't done its job. I'm always paranoid about my bullets after a few failures on head shot roos with highly frangible bullets.

Is the 222mag factory 1:14 twist? Might need 1:12 at a minimum to stabilise 60gr. No direct experience with the partition projectile.

[Am88]

Got the rifle built to 1:12 mate.

Is the 223 fast twist

In my 12 twist 223 they stabilised but hovered a bit below 50mm groups at 100m. Haven't shot any game with em as yet.

I get under inch groups with 53gn tsx.

No Mate just a 12 twist .223. I found another option being 55gr Oryx by Norma, might be worth a look too

G'day Am88 , mate i use Oryx 154gr in my 7mm and i find them perfect they hold together well and shoot well i'm getting 12-16 mm moa which is as good as any other bullet , only one thing with them is they're a little pricy but not too bad.

l have in the past had issues with 55gr frangible bullets head shooting roos,
l found l had to keep my shots at around 120 and shoot in the back of the head for better success, sometimes having to pass up a shot or waiting a while before the shot presented. what l use in my 22-250 successfully is 50gr nosler shots that has a 1 in 14" twist but have found 60gr sierra hp's hard hitting and do the job no worries in my 22 dasher https://www.sierrabullets.com/product/2 ... -60-gr-hp/

Yes marksman i found that with the dogs with the 55gr vmax in 22 250 , when i first started using them 10yrs or so ago they were very good but the last yr or so i've seen a change in the knock down power of them , some blow up and dropped the dog instantly and some pencil straight through , leaving me looking for a dog instead of looking at a dead dog, since changing my barrel i've started using the standard sp 52gr hornady f/base but stepped the speed up from 3414fps with the 55gr to 3850fps with the 52gr and they ''Kill'' perfectly and cheaper also deadly accurate

If I’m useing a light calibre for smaller stuff and there’s a possibility of a bigger animal. , and I want a tougher projectile I go straight to a Barnes x. Costs me a fortune but I’m not buying packets of them

[Am88]

Hi All, once I swapped to the Sierra 1365 Game Kings I had much better results on the roo's. but, have had mixed success with them on the deer hence want something different. the oryx is saying it's bonded, that would be a great little bullet by the look

[rossfrb]

Cheap to try would be the Speer 70gr semi spitzer (supposed to be a stout enough projectile). Some places recommend 1:10 or faster twist but I can find references on the successful use in 1:12 twist.
Not tried them myself.
That the Partiton is shorter than the Speer would then suggest it might also work in a 1:12 twist.

Would be great if Woodleigh made a 55gr PP SN. But can't have everything
