..... I just wanted to get some hunting practice.....
Simply put, YES, buy yourself a Skeet choke (Cylinder will work just fine, so will Improved Cylinder, although it's a little tighter) ... and a Full Choke (Improved Modifies will also work)
Skeet is a game where a more open choke is advantageous ... all targets cross the center stake out beyond 8 ... from Stations 1-7 that's exactly 21 yards ... about 1/2 the distance a Full choke works best at. From Station 8, most shots are even closer as the targets cross 6 yards out and approximately 6 yards up ... both shots from Station 8 are taken at a distance of about 8 or 9 yards ... pretty close !
Trap is more about distance ... from the 16 yard line (the closest set of "stations" behind the trap house) most Trap targets are taken at about 34 yards ... for an experienced shooter who knows the game and has already developed a smooth swing and rhythm in shooting his(her) targets. New shooters will most often attempt their targets a little further out. Many find that a Modified choke works well at 16 yard rise, but more often, the experienced shooter wants something a little tighter, like Improved Modified or even Full. In competition, the better your registered average in handicap, the further back from the 16 yard line you go. When you're really quite good, the maximum "handicap" distance is 27 yards back from the trap. From there, it's pretty much a Full choke game.
Sporting Clays & 5-Stand seem to offer a variety of shots and distances to the target ... and there is no set standard. Shooters or varying skill will use all manners of chokes. For the most part, Improved Cylinder or Light Modified work for the majority of Club layouts.
Extra chokes aren't much money in the grand scheme of things ... a pair of standard Remington chokes shouldn't be much more than $25 or $30 each. With the Modified you already have, a Skeet and a Full should cover most bases for you.
If you want to get some "hunting practice" ... and by that I take it you mean wingshooting, I would recommend Skeet as the place to start ... and stick with it until you can regularly break in the 20's. Skeet was originally invented by a group of grouse (or partridge, if you will) hunters in New England to simulate the type of shots they encountered while hunting grouse & woodcock. As it's since developed, the game still gives you a great variety of target presentations ... going away, incoming, quartering and crossing, both from the high house ( relatively level flight)) and low house (rising). The repetitive nature of Skeet, once you've learned the stations (foot position, hold points, how much lead or forward allowance is required to break the target and follow through)
will provide a solid foundation for both your field hunting and shooting the other target games. Others may have a different opinion, however Trap will give you good reference for going away shots, while both Sporting Clays (some have referred to it as "Skeet in the Woods) & 5-Stand ("Sporting Clays without the Walk") provide a great many target variations ... are initially much more difficult to master than Skeet. I'm not saying avoid the other games, but spend your initial time in learning to shoot Skeet and the other games will come somewhat easier.
A little coaching by a good Instructor, development of good form in mounting & shooting, ensuring proper gun fit and some judicious pattern testing will all contribute to better shooting in the field. That and say 10-15 flats of target shells on the Skeet range between now and September ... you should notice quite a difference.
Good luck. Buy a couple of chokes and lots of target shells and get out there shooting on a regular basis !
