I ran my 1.5kw amp into a kilowatt capable antenna tuner then into wire
antennas all the time.

Your SWR is only going to be perfect 1:1 on one specific frequency only.
Jumping 0.3 SWR across any band is within normal for any wire antenna.

Consider installing a high power tuner after the amp.

OTOH with a solid state rig it's a good idea to get it below 2:1.
My 756 Pro will operate pretty much the entire 40 meter band with the 
internal tuner. However the solid state amp (Tokyo Hy-Power HL-1.5Kfx) 
shows a substantial power drop with 1.2:1 compared to 1:1.  At 1:1 it 
runs 1 KW out. At 1.2:1 it is down to a bit above 800 watts. At 1.3:1 
the reflected power will start tripping the protective circuitry.
