Barrel Contour Comparison

[Walsh]

Hey ya'll quick question. How much difference in contour is a GI 03A3 barrel and a Light Palma contour. Also, what does the GI contour most closely resemble and what does the barrel weigh

I ask because I want something that will not heat up as fast but still be able to be medium weight. I am trying not to flute because of the extra cost in doing so, although if it really came down to it, I might could.

Thanks,
Walsh
