MustangMan,
For starters, what guns do you own. If this is your first high power. Then you may want to re-think your list.
List is price of rifle and ammo.
1. Ak-47(sar1), rifle is $350. and ammo is $80. for a 1000 rounds. Great for shooting in pits and short distances(less than 200 yds). A must own for any auto rifle shooter.
2. AR-15, rifle is $600. and ammo $95.(wolf) for 1000 rounds. Mags are $15.00. Great for shooting up to 300 yds and rifle has no recoil.
3. FAl, Rifle is $600. built and ammo is $140. for 1000 rounds. Mags are $9.00. Great rifle for shooting at the range. Built correctly will shoot less that 2MOA, but a bit long in the stock for exstended off hand shooting. Has a adjustable gas system so you can taylor the rifle for any 308 round. The felt recoil is smooth due to the gas system.
4. Hk91 or clone, true HK $2500, Clone $1000. ammo is $140. for 1000 rounds. Mags are $10.00 from Aims. Great rifle for shooting off hand, but leaves a little to desired on the bench. A few hundred rounds will leave a mark on your shoulder(bench shooting) The rifle has a shorter stock than the FAL, which helps in shooting the rifle off hand. The rifle uses a delay blow back system rather than a gas system. It works off the negitive pressure spike of the barrel pressure to allow the bolt to unlock. When it unlocks, there is nothing smooth about it. To cock the rifle, you have to let the bolt slam home. The trigger pull(stock) is not for the weak. And the rifle is not the prettiest,full of weld spots and lines. There are two lethal ends on a 91. One being the muzzle, the second being the ejecting port. The brass is ejected a good 20' out.
Granted that I love my HK-91, but for some people, it is a bit too much rifle.
All you have to remeber is that once you have the rifle, you will need to feed it. The reason that I have included ammo price is that you will be burning it up real quickly.
Also, the reason I have included the Ak-47 is that It makes a great starter rifle. Mags are less that $6.00 and came be had by the handfull. The rifle will run even it you don't clean it for months at a time. If you like, you could get a SKS, but the mags are $30.00 and some are junk due to weak feed lips.
Start with what you can afford to buy and shoot. Then as you start to make more money that your wife can spend(helps to hide it in secret savings), you can buy the rest.
