40gr bullets in a 1:8 twist 223?

[ColinBr]

Anyone using 40gr bullets in there 1:8 twist 223?

I was wondering if they would stabilise in the faster twist barrel, as I've got some V-Max here I was hoping to use.

Thanks
Colin

Anyone

Have a listen of this - a discussion on fast twist rates in 22 Swift - I think it was the 2nd question discussed.

Pretty much you can overspin a bullet. But some bullets may not with stand the high rpm and associated centrifugal force.

Unlikely mine is 1:8 and 60 v max is lightest that it would shoot.

Not going to happen in a 1:8 .223 though at 1000 fps less. You do post some strange things!

I shot a lot of blitzkings from a 1:9 .223, very tight groups.

They will not necessarily be optimal but as you already have the bullets definitely worth a try.

I've shot 50gr gamekings in mine no probs. 0.25-0.4 moa at 100 yards

I've just loaded some 40g for my 1:9 24" CZ527. I recall they shot well in my American 20" out to 200 yards. Opened up badly beyond that. Have also loaded up some 53g Vmax. The factory ones were average, at best, so hoping the reloads perform better. 60g Vmax reloads are very accurate.

Stabilisation is not the problem - ir's spinning too fast that's the potential problem'
A lead core/copper jacket bullet can fly apart from the centrifugal forces produced by the bullet spinning too fast
Having said that, I've run 35g Hornady NTX in a 1 in 9 twist 22-250 without any problem.

WTF did say anything about 1,000fps or less.

The blog was about overspeed on fast twist high velocity .22 centrefire.

A 220 swift is going to be pushing a 40 gr bullet about 1000 fps faster than the OP’s .223, ok in reality 5-600 fps but it’s a big step up.

A .223 is not a high velocity .22 CF and the centrifugal force imparted by a 1:8 is not going to pull a 40 gr v-max apart.

I've got a box of 40gr Vmax and a box of 40grNosler Ballistic Tips, but both my 223s are 1:8 twists. I thought the problem was that light bullets might get the copper jackets torn off trying to twist them too fast at the speeds they are likely to be driven

 

[ColinBr]

Thanks all

I'll build a load up and see how it goes. I can imagine a pretty large jump to the lands with these small bullets.

Is your .223 non standard?

If not it will be fine

 

[C h r i s]

Use them all the time, 40gn Vmax in a 1 in 8 twist Tikka. Shoot sub half moa.

Standard Tikka T3x 1:8 twist

22-250 with 8 Twist Questions

Anyone out there with a 1:8 twist 22-250? About to pull the trigger on it, but I'm hesitant. Has anyone fired factory ammo or 53gr V-max out of one? I'm wondering if the twist rate will be too fast and tear up the jackets? My favorite varmint load is 53 vmax at 3800 fps. Its a great fast, flat...

A couple of people on this thread using 40 gr bullets in fast twist (1:8 & 7.5) 22-250s, v-max in the 7.5 at 4150 fps. No bullet blow, the other is using the noslers.

I personally have shot 30 gr cup and core bullets nudging 4000 fps in a 1:9 .223, no issues at all.

They will be absolutely fine in a .223!

Standard Tikka T3x 1:8 twist

So it will have a standard throat and handle 40 grain bullets fine. There is no need to chase the lands!

 

[stephentri]

In my 1 in 8 twist .223 50g vmax are fine, 40g vmax didn't group just as good

Yes I was going to go by the general rule of 1 x dia of bullet seating depth. Ie
224"
