After having multiple hand an back surgeries I've found myself unable to practice enough with a compound bow to feel as proficient as I should hunting.  I dont know much about crossbows but it seems a lot of crossbows list fps with bolt weights that aren't readily available

Looked at the TenPoint Nitro X first but when compared to crosman gladiator whisper 405 the price difference  seems a lot.  Then I saw the crosman comes with 3 390gr bolts (including broadheads)  that will give the 405 fps.  Having a hard time finding replacement bolts of similar weight.  What's the deal? Or am I missing / misreading something.

There have been a couple crossbows where I've seen the fps with a * and "with ___ bolt weight"

My first, and only, bought about 3 years ago, is an Excaliber.  They are recurve crossbows, just love the simplicity. Check out their lineup.

Barnett Crossbow

I've had two crossbows I refuse to spent a thousand dollars for a crossbow there are several useable Barnett models that are worth a look.   Speed means that the arrow trajectory is a little flatter but at 15 to 35 yards you don't need the fastest one to shoot through and through.

Take a look at several and see what you like; for a value crossbow the Wicked Ridge and Centerpoint Snyper are very popular.

I've only owned a crossbow for a couple of years but I bought an Excalibur micro 335. Only $750 for the kit and I shot two deer last year. Anything over 300 feet per second is fine for deer hunting. The 335 is small, narrow and easy enough to shoot from a gun blind. To echo another poster the recurve system is super simple, no tuning needed every couple of years and you can change the string by yourself in 5 minutes. I looked at the prices in the latest Cabela's catalog and I think $1,500 for a crossbow is ridiculous. Your mileage may vary.

I have restrung my Invader; sure it takes longer than a recurve but it doesn't take a rocket scientist now

Don't buy a crossbow on one person's recommendation. There are pluses and minuses with nearly any crossbow. The very best ones the only minus is the price. There is a wide range of different bow speeds among the different manufacturers, and there are advantages and disadvantages to having a fast bow or one that's not so fast. I suggest you go to www.crossbownation.com Lots of knowledgeable folks there who are always willing to help. Various forums for different crossbows with detailed information about their bows.
