The T/C Hawken is a fine rifle -well-made, durable, and reliable.
That said, I wouldn't trade my Lyman GPR for one. But when I bought my GPR, the GPR is what I wanted. If it was more expensive than the T/C, I'd have bought it anyhow, and I wouldn't have given the cost of admission a second thought.
I can't remember how much my GPR set me back when I bought it two decades ago, but I know how much I spend shooting it each year. I am a fairly high volume shooter, and am shooting something three days a week. I spend a whole lot more on the lead I send downrange than the hardware I launch it from.
I shoot blackpowder, adult airguns, and sporting clays with cartridge shotguns, for the most part.
I shoot sporting with an ancient 1950s Browning A-5 Light 12 that I paid a whopping $300.00 for.
I run the course two times each day I shoot it, and I shoot it twice a month. Each month, I spend slightly more than the purchase price of the gun itself in shooting it. Just feeding my sporting clays habit sets me back $3,500.00 a year in ammo and range fees. I expect that I'll be shooting that A-5 another 30 years, at least. Ammortized over time, I am paying ten bucks a year for the gun, but I'll be paying AT LEAST $3,500.00 a year to keep shooting it as much as I want.
That's really the long-winded point. If you plan on shooting your trad. rifle a bunch, you'll spend a whole lot more in shooting it each year than the piddly difference of $200.00 between a Lyman or T/C. So if the T/C is what you can see yourself shooting freqeuntly over two or three decades, that is the gun to get. You only have to buy either of them once, after all. Might as well go for the one you'll get the most pleasure out of, because over the long term, you'll spend significantly more money on shooting it than you'll have spent to purchase it.
