Hello everyone!
Thanks for the responses.

Poprivit: indeed that is the article! Despite the bleeding arm, how did you find it? How heavy was that gun, how'd it compare to other calibers? What we're the sights on that rifle? It others you've seen? (like, standing/ folding and what yardages?). Any stories from anyone you know who have used them on game?

500grains: what else did he have to say about it (any stories?)

DrFM: thanks for that, I'll look into ordering it

So far the general consensus from all I've heard/read is that they're too heavy.

But as a "fun gun"... I wouldn't mind copying Ed Hubel and building a savage 210 bolt action shotgun into one. Weight around 17lbs or something.

Cheers guys,
Ash
