Haviland listed 35 gn of TAC with 40 gn Sierra Blitz Kings and WLR primers. He reported 4139 fps from a 28" barrel.

I have never tried 40 gn bullets but 8208XBR worked well with 36 gn Barnes Varmint Grenades.

My favorite load these days involves 50 gn Ballistic Tips, Big Game and 210M primers. IMR4064 is another candidate for accurate loads.

In decades gone by plenty of ground squirrels were splattered with 55 gn Hornady SX and IMR4064 even though a smoke trail was sometimes visible all the way to the target. The 1:14 handles 55s just fine.

I won't divulge my powder charges because my Model 70 needs to exceed published loads by a couple of grains to equal published velocities.

Cheers,
Walt
