Maybe a bit of topic but.......
I would like to shoot tracer out of my No4 303.
303 tracer is,to say the least,rather scarce.
I do have however some 144gn 308 tracer.
The tracer I have is nominally 307 and my No4 slugs at 311.
Is there any reason I couldnt paper patch these to make em fit?
I am thinking this may be tricky on account of only having 4 or 5 thou to play with.
Accuracy isnt a big issue,its just for fun and "can I do it?".
What do you think chaps?
