Is the 223 & 22-250 bullet head the same ?

I tried a box of Hornady 40g v-max, and a box of Federal 40g BT v-shok, both accurate but there was a more noticeable amount of fox runners, the impact noise was also reduced.
I'm not suggesting that 39/40g bullets in 204r is like this because i don't know.
At the end of the day you have to use what you have confidence in, for me its 50g-55g v-max type bullets.

Isn't there a minimum of 50g bullets in certain calibers for deer, there must be some reason for this.

Sounds to me like it's time you got yourself over to your local gunshop and ordered/bought a new rifle. Get rid of the confidence sapping .223 and buy either 22.250 or .243, if bigger is better then either of those will cure your problem.
