You know it's kind of funny, because hunting these prairie dogs is what really got me to thinking seriously about adding a .25 to the battery. Somedays I spend as much time chasing my hat in the wind as I do hunting. Well, maybe not quite that bad, but you get the idea. The faster the wind blows, the closer I need to get for a reasonable chance at a killing shot. Sometimes that's only 50/55 yards. The wind causes the pellets to turn into curve balls and sliders. When possible, I try and keep it at my back, or in my face, but that doesn't always work out either. I'm thinking that a .25 cal shooting a 27 to 31 grain pellet at around 900 fps would buck the wind better and let me push those ranges back out to 65/70 yards. Come June, when prairie dog season opens here, I'll get a chance to see if a .25 makes any real difference. Should be fun.Cliff your .25 Maurader may be just the ticket for Prarrie Dog hunting...be interesting to see results of your hunts on those critters...long range,wind,etc..

I think we're only about a week or so away from getting into the forest around here. I'll get some 50/55 yard groups then. I'll be doing some chrono work as soon as the other pellets get here, and that should be some time next week. My California squirrel hunting trip has been rained out twice now, so that may not happen this year. The local prairie dogs will be expected to pick up the slack.Those are very nice groups Cliff. I think you have a real winner there. I also agree with your reasoning on why a .22cal would be a better all around choice. But being that you have an excellent arsenal of airguns it is a great addition. Thanks for showing us what it can do so far. When you get some chronograph readings please let us know.

Cliff I think you're going to have a lot of fun with the .25. With the magic you've displayed here an on other sites with your .22's, I believe the .25 would extend that range. I am absolutely confidant that the .25 in a relatively heavy pellet, 31+, bucks the wind better than most if not all .22's. Ofcourse density has a lot to do with it. I wouldn't recommend using a 43g EJ as your go-to lead, because of drop, but it's amazing in the wind. 31g H&N seem to be very uniform and/or even the softer leaded 35g EJ tears them up at distance, even sans a headshot."....27 to 31 grain pellet at around 900 fps would buck the wind better and let me push thos ranges back out to 65/70 yards."IMHO with your markmanship, it won't be long before that range, sans wind, using a .25, will be extended by 10-15 yards. Find your go-to pellet.You know it's kind of funny, because hunting these prairie dogs is what really got me to thinking seriously about adding a .25 to the battery.

Don't forget that to buck wind, flatten trajectory and have a maximum impact velocity you need a good ballistic coefficient. Unfortunately, the 27 - 31 gr .25 pellets have a BC of .022 or .023, Not as good as several of the .22 pellets. The JSB Exact, a 15.74 gr .22 pellet has a .032 BC, while the .22 Kodiak and the .22 Crow Magnum have .035 BC. The BC king of both the .25 and the .22 world seems to be the Eun Jin .22 caliber, 29 grain pellet with a BC of .047. Of course these BC's are puny compared to the powder gun world but, the further you stretch the range the more difference they make.I'm thinking that a .25 cal shooting a 27 to 31 grain pellet at around 900 fps would buck the wind better and let me push those ranges back out to 65/70 yards.

I think some of the numbers you have are a bit off. Here's the chart that I get my info from. It shows the BC for the 31 grain .25 cal Kodiak to be .037, the 21 grain .22 Kodiak is shown to be .036, and the .22 Crow Mag to be .022.http://www.airgunfor...ts-bc-info.htmlDon't forget that to buck wind, flatten trajectory and have a maximum impact velocity you need a good ballistic coefficient.

I've read where guys have shot them with .22 rimfires and they still take off. I've hit them with .25 43g EJ's clean thru, mid-section, and they still run off. I don't believe it's overkill. I'd use a .22 rimfre in my backyard if it were legal. Most people that have experience shooting squirrels know how tough they are pound per pound.BTW, none of the squirrels on property from where I shoot off my back porch reside within 50 yards. They're out there from about 50-140. I don't go after the 50 or 60 yard squirrels like I did last season. I want this season to last a bit. 31g H&N at 950 fps was able to handle the unfortunate squirrel at a lazered 142 yrds. with a 2 dot holdover, and about a 20% downgrage. A 20% larger wound channel makes a difference.Marino....LoL @ shoooting squirrels with .25 cals, thats funny stuff. kinda overkill

Well here is the chart I used, from Straight Shooters. Straight Shooters Ballistics Chart I believe they test and develop their own data, rather than inviting people to send in ballistic coefficient data. But it is interesting to have multiple data sources.I think some of the numbers you have are a bit off. Here's the chart that I get my info from.

Here's another list of BC's that you might find handy on occasion. http://www.airgunexp...undb/pellet.cfmWell here is the chart I used, from Straight Shooters.

Thanks, it's always good to have another reference list. Now if I can just find a source for the Beeman Crow Magnum 26.2 gr, .25 caliber, the ones with the .230 BC. With those and a 1001 fps muzzle velocity you could put 50 fpe on a critter at 100 yds. That would be 929 fps at 100 yds. It would have a 10 MPH wind drift of 2.1". Unfortunately that BC was undoubtedly a typo.Here's another list of BC's that you might find handy on occasion. http://www.airgunexp...undb/pellet.cfm

Lucky you! My Disco loves them, So when I bought the Mrod I thought it would too. But it doesn't shoot them good at all, especially compared to other pellets. Did you have work done to your barrel? or is it a Mac 1My Marauder likes JSB's and that's all I feed her.

Same here John. Mine will shoot the 15.9 JSB's, 18.1 JSB's and the 21 grain Kodiaks extremely well. In non-lead ammo, mine shoots the DYNAMIC PCP-2's lights out. On the other hand, it wont shoot Crosman pellets at all. Mine is also from Mac1. You just never know what a given gun will like.My Marauder likes JSB's and that's all I feed her.

Lots of people like the mil dot reticules in their scopes for the multiple aiming points and calibrated distances between the dots that they provide. Others like the better brands of scopes as they provide repeatable adjustments, if you are accustomed to dialing in sight settings for varying distances. How do you normally use your scopes.Thanks John! Done deal! I will get it ordered this week.. Now we get to talk about optics for this baby!!
