Gentlemen,

I finally got a chance yesterday to chronograph the Woodleigh Hydro's again in my Zastava M70 with 24" barrel.

Originally I was after a velocity of around 2200fps so I started with 75gn of BM2 and got a velocity of 2318fps.
There was no excessive pressure signs but then out of curiosity I then dropped to 74gn and got the same velocity.
I then lowered the charge to 73gn and finally got a chance to chronograph them.

With 73gn I got a velocity of 2287fps for a healthy 5227 ft/lb of energy.

l will leave it at this powder charge as velocity is nearly the same as the 75gn charge - and as a bonus it is the same powder charge as I use with the 550gn Woodleigh, my other load I use in this rifle.

I'm very happy with how this experiment has panned out - an easy 2280fps with a 450gn projectile has made this a successful venture.

You'll probably never NEED a gun. In fact I hope you never do. BUT IF you do, you will probably need it worse than anything you've ever needed before in your life...
