I was all prepared to buy an AR20 when I came across the Walther 1250 Dominator. Any thoughts between the 2?

David, do a search on the AR20. There was a long thread about them a few months back. Lots and lots of info IIRC.

Which dominator are you talking about? The FT style dominator is a very nice gun...

I think I have decided on the 1250 Dominator combo .. Now, what is the difference in the calibers .177 .22 and .25

I was wondering if the ammo itself would be different, like not readily available for the .25

.25 is a little less common than 22 and 177, but not "hard" to find

Here is what I have been reading on Calibre

By far the largest number of airguns are sold in .177 caliber, and this is the pellet size of choice for nearly all target shooting, plinking and some small pest hunting. .177 caliber offers the highest velocity for a given amount of airgun energy, and results in the flattest trajectory. However, the speed of sound--1080 fps at sea level at 32 F sets a practical upper limit on the energy with which a pellet can be propelled. Breaking the sound barrier results in a loud crack-just like a firearm and generally sends the pellet tumbling wildly.

It would take 16.8 ft. lbs. to propel Beeman's Laser pellets to 1080 fps. and 21 ft lbs. for Beeman/H&N Match pellets in .177 caliber.

.20 caliber (5mm) is a perfect example of obtaining large ballistic gains in performance with small, optimal changes compared to .177 caliber. The 5mm trajectory remains nearly as flat, but its heavier weight lets it carry about 40% more energy for the same velocity. This is the best general purpose caliber. The

.22 caliber has a large gain in pellet weight and size and is only usable in the highest-powered hunting rifles. The range of the .22 caliber is less than the .20 caliber, and the downrange energy less than the larger .25 caliber pellet. .22 might be the choice if you owned a single hunting rifle.

. 25 caliber is unbeatable in carrying the most knock-down force to the target because of its maximal pellet weight and resulting incredible shock value. It is the perfect round for the tough tree squirrel and the right caliber in high powered air rifles for any of the larger furbearers such as woodchucks, opossum and even raccoon.

My .177 Hatsan runs 968fps with 10.34gr. JSB's - that's 21.5fpe and will do nicely for gophers or bunnies, to about 50 or 55yards using only the crosshairs and a 1/2 mil Dot slash. The larger calibres packing more killing power & probably long range accuracy, will extend that range if needed - just ask Bob.

So If I am only interested in Target shooting but want better long distance accuracy I should go with the .25 ?

Bearing in mind you are posting in the Field Target Forum.... I would think you would be better off with .177.... Pretty tough to squeeze a .25 cal pellet through a quarter inch hole....

I would be surprised if a match director would allow you to use .25 cal on a field target. The 20 ft/lb limit in FT would also mean that the pellet would have to be going quite slow and result in a terrible trajectory curve.

If indeed you are considering FT, as Bob suggested, .177 is the way to go if you are at all serious about doing well.

FWIW, I will not allow .25cal at any Chatham matches, too much damage to the targets...

.177 is the choice for FT - flatter trajectory.

Ditto for Ottawa.
