2.5 acres is not large...
?
OK maybe for where you live.
My lot is less than 5,000 square feet, which I think is less than 1/8 acre.
You need to look around and measure range for yourself where you would likely shoot from and to. Visual guessing is tricky and it is very easy to miss-guess, at least for me. I recommend getting/borrowing a 100ft tape measure and do a few measurements. That way you KNOW how far you will be shooting. The pellet impact will change based on range, so this is important for you to know and practice.
#5 If you read many postings on the various forums you will see references to tuning a rifle.
This has a decent write up about what a tune is.
http://charliedatuna.com/Tune-ups.htmI asked CharlieDaTuna about tuning the Gamo Delta, he recommended only replacing the trigger. I think it was because you can buy the Delta for about $60-70, but the tune would be more than 2x the cost of the rifle.
#11 get a box of cheap pellets to practice with. After you shoot thru a box of pellets, the rifle should be "broken in" and you should be familiar and comfortable with your rifle. Ideally at this point you can shoot, with the rifle on a rest, reasonably tight groups of 5 shots at 25 feet or 10 yards (30 feet). Ideally the groups should be an inch or less at 10 yards. If you have trouble getting a good group at 10 yards, you should work on technique before proceeding. This is where it is easier to shoot a Single Stroke Pnumatic (SSP) or a co2 than a spring rifle. The recoil and vibration of a spring rifle makes it harder to shoot accurately. The trick is consistency. Hold the rifle the SAME way each time, as how you hold the rifle will affect where the pellet will hit.
Then set up a target at the range you expect to shoot mostly at.
Then take the "sampler" and shoot at the target, say 3-5 shots per target for each type of pellet.
What you will see is that the rifle will not shoot some pellets well and will shoot nice groups with other pellets. That is the purpose of this exercise. Now you know what pellets will shoot accurately out of YOUR rifle, and that is the one to buy.
You NEED to do this at the range you expect to shoot the wabbits at. Different pellets may shoot better or worse based on the range. Example, wadcutters (flat front pellets) typically don't do well much beyond say 15 or 20 yards, and pellets with round noses typically do better at the longer ranges.
As for why the 10 yard test. From my experience, on my 10 meter (33 feet) range, any pellet that I've tried has been acceptably accurate out of any of my rifles. This includes the cheap Daisy and Crossman pellets from WalMart out of my inexpensive Daisy 953. The same pellet and rifle might be a disaster at longer ranges. This is why you have to test at the range you expect to shoot at.
If you decide on co2 for easier shooting, take a look at:
- Chinese made QB78, many people like this rifle. This guy seems to have good feedback:

- RWS 850, A newer rifle that I've read several posts that people like it.
These are full size rifles that you will have to have the stock shortened for you.
