I honestly donot know what the addedlength of a normal Lyman GP barrel does versus the length of the Trade Rifle, but I can shoot heavy conicals very well from my 1/48.
I use Bullshop or No Excuse 460 grain .503/.504 bullets. I am partial but I really do like the Bullshops better...
I can consistenly break clay pigeons placed at a 100 yards with open sights off a portable bench and bags.
Here is a 50 yard targetshot with a TC Renegade. It was a testtarget trying to get velocities.
