nice rifles! The 453 in a 17HM2 may be quite the hunt. The 453 american 17hm2 is quite rare and the 453 varmint in 17hm2 I have never seen one for sale. They could be described as unicorns. Good Luck with your search.
True statement and I wish you luck.
I acquired my 453 17HM2 almost 15 years ago and after shooting it immediately started looking for another. I haven't come across a single one that I could have actually purchased in that time. I hear they come up, but I've not seen an actual gun to purchase.
