Sorry if this has been done before ,I missed it.
I'v been thinking of bullet choice but only the copper bullets like Barns 7mm ttsx ect, anyone had a play with them out of a 280 ack imp ?
be happy to read about it ,inc bullet choice load, coal, you know the boring stuff we reloader's read about.
Just in 7mm please .
I use 140gr btsp at this time real nice bullet and works well, but would like another choice to try out.
