Hi all, might be building a brush gun in the future for short range hunting in california zones so avg shots would be within 150yrds but would like to take it out to maybe 500yrds if needed. Will be building off a tikka t3 currently in 270win. Was thinking of 7mm-08 with 18” aftermarket barrel using Barnes 120/139/140/145 gr ttsx/lrx. I reload so I can play with velocities. Hunting deer, bear and hog. Thoughts on this set up? I also have a t3x superlite in 270win.
