A couple guys on another board have converted 35s into SMLs. The performance is quite astounding too. Our minimum is 40cal though so i never really paid much attention to them.
I thought about a whelen when I started my last .36. This next one should be right to shoot .35 whelen as bore riders. Maybe try some paper patch. Im kinda hoping upping the speed past GG restrictions may give the range. still a few months out.
