6.5x47 suppressed - barrel length advice please

I am researching info on a Lapua 6.5x47 - that I want to shoot suppressed with my Thunderbeast 30P-1

What barrel length do you recommend?

Short range ( under 300 yards) hunting is the goal.

I hand load so do any of you also have a load that works well with this barrel & suppressor combination?

I am having the receiver, bolt and barrel custom built. I will install a Timney trigger and McMillan stock.

Thanks
RFA
