Ha ha yeah no, not even close to a 9" twist.
I kind of got lazy with my shooting as I used to use 130gr hollow points in my .308 and any misplaced shots still did enough damage and left enough of a blood trail to ensure very few animals ever got away.
Since Ive switched to .223, Ive had a Whitetail doe, a Red stag and a Sika spiker get away, which has left me with a 3 from 6 success rate, which is no where near good enough. All with 55gr Hornadys.
I'm not sure if they were hits or misses, as no blood was found and no animal, even after a lot of searching.
I like the idea of heavier weight projectiles for now.
Some time at the range will determine what I use as a hunting round moving forward.
1 inch groups at 50m will be good enough for what I want to do.
Long term a rebarrel could be on the cards.
Those numbers on box are surprisingly good. I have used the 50 grn ttsx with great results. But I keep range under 150yards.they kill well
75/15/10 black powder matters
They need a 9T or faster.

Recommended Twist: 1:9” or faster
Slow twist you MIGHT get a 40-45grn mono to stabilise but most are too long so need faster twist.

Would an unstable bullet still be stable enough to 50 odd meters? or would they be horribly wonky from the muzzle?
I'm not shooting too distance, only bush hunting ranges so i don't need super accuracy.
I wonder how effective or uneffective a unstable projectile would be at close range.
I wouldn't do it....you know that sooner or later you will get only chance of day at hundyish and will wound or miss. I've been down this track and it's bloody frustrating and just not worth the hassle. At the sub 150 ranges the 50-55grn or even up to 64grn Winchester factory stuff work fine.

223ai up and running. 16" 1:7 twist chucking out the 88 eld's at 2600, or 62gr coppers at 3000.
HT-70LRF bang on out to 800m. Mostly wallabies but deer are gonna be in trouble too!
