Gerhard.Delport500 Jeff Cast bullets
Guys please help,
I want to shoot 500 jeff cast bullets for practise as I can not afford to shoot GSC or Woodleigh bullets trough paper...
Now some people are telling me that its not a good idea to shoot lead bullets in the 500 Jeff

I am going to use gas checks on the bullets...
Please advise...

Paul HI shoot cast out of my 500 Jeffrey.
The one problem with the Jeffrey when shooting cast is the short neck. With a bottle necked case, you really want to keep the base of the bullet in the neck for the best accuracy. Whenever I've deep seated a cast bullet in a bottle necked round the accuracy was poor.
For the Jeffrey I found the slightly lighter cast pistol bullets, i.e the 450-470 gr designed for the 500 Linebaugh worked very well as they kept the bullet base in the neck. You could load them very mild ~30 gr of unique for 1100 fps (giant 22 rf

) or on up as fast as you'd want to drive them.
In general I find the bigger bores are more tollerant of shooting cast bullets, especially if you keep the pressure and velocity (2000-2200 fps) on the moderate side.
