Depends on bullet length, not weight. A blunt FB SP 60gn might work just fine, a 55gn BT might not.
Boat tails and polymer tips make bullets significantly longer than a flat-base exposed lead nose of the same weight.

I was chatting with a guy on FB the other day. He has a .22-250 12"-twist and reckons the Speer 60gn SP works fine. I don't know if it will be but might be worth a try if you're looking for a heavier bullet.

If they're the same design then heavier will be longer. Start comparing boat-tails, monolithic, HP and BT though and the differences get significant.
Just looking at Hornady they have six 55gn bullets varying from .697" for the soft-point up to .808" for the boat-tail VMax BT. They offer two 60gn bullets that are shorter than the VMax. A Barnes monolithic brass 55gn bullet though is up to .898" long - 5mm longer than the Hornady SP.

caught up with stoney in person this arvo, and he was kindly gave me some 60 gr vmax to try . i know what your talking about with bullet shape and length, in my 22 krico hornet it loved these short fat sierra "hornet" sp that shot better than 40 vmax. ya wouldn't have guessed to compare the two......

I will be doing some testing in the New year. My plans is to use the 55g super roo as my projectile. Cheap cost effective have to wait and see. Fingers crossed the combo works.

funny you should say that azza, i picked up my 222 winchester on wednesday from swan's . mine was in just for the barrel . hopefully yours wont be too much longer. they're flat out though, allan rang me at 7:30 at night to tell me it was ready
bigrich wrote:the only winchester ammo that's worked for me was 22 hornet 46 gn hp's . under 1" at 100 out of my rifle. wasn't cheap though there is a lot of 22 projectiles out there, i had bin using nosler 50 gn bt's. these are a sturdier bullet than vmax supposedly with a thicker base to prevent blow up.i also have 50 hornady soft point flat bases, which were about $29 for 100 i'll shoot some different ones and just see what works i guess . i'm not a high volume shooter, so cost isn't as important as accuracy and projectile performance to me

I have other rifles that I intend to shoot more the 222 will be a designated hunting rifle my expectations of a bullet are a little high but kind of a given as i dont want to educate foxes/cats by missing them. If i can find something that i can shoot around a1inch- 1-1/2 @ 200 ill be happy.

That being said hate hearing a crunch when reloading too.
