Just to tie it all together,
I am back in the 35 whelen game, but not with an HR product.
I bought an Addams and Bennett barrel for my 30-06 Savage. Then I spent a fun filled week building a vise to hold the gun to break the factory installed barrel nut and swapped the barrel. Dusted off the dies and components for the Whelen, this time I bought some RL15, and 4 of 4 shots fired. Results were much better this time around, too bad its a year later. But, maybe it was a blessing in disguise, I now have the 25-06, and have another barrel changing platform to feed my obsession.
