Any one here have any experience with the RWS Diana 48 in .25 cal ?? if you do can you please comment on the performance of this particular caliber especially if you have crony #'s to the performance It can deliver. I'm looking for ballistic information and fp's it can deliver to the target intended. The targets are rabbits coons and possums and lets not forget crows and squirrels, but not in that order LOL.
I know that this .25 Cal was made in the RWS 52 any info on this one will also count. thanks in advance, yf dan

the .25 was a flop in the rws 48 range. all reviews gave it a bad rep due to the low power generated. it was not meant to be a .25. the .20 caliber in the other hand is the most sought after... never find a used one. skip on it and get your self a RX2 beeman with the theoben gasram... in .25 it was shooting eunjin pellets (38 gr.) at 596 fps avg. and it shot .25 lasers at 730 fps avg. Not a long distance sniper system but with the eunjins it would go thru a 5 gallon spackle bucket at 15 yards cleanly... the rifle is also very quiet and the impacts are glorious...
-
Thanks for the info greatly appreciated i wanted the rifle for my daughter as she just plinks but plinking 25's might be to expensive LOL, yfis. dan

Gabe is right about the .20 cal 48's, real sweeet. I got a brand spanking new one, still in the box with tags and paperwork, 2 years ago and she's awesome :) she's one of the favorites in my collection.
Haven't seen anymore of them though, not even used..... harder to find than hens teeth.

If the 48/52 isn't powerful enough for a .25, then how can the new crop of Chinese guns be so great? Is the Nitro pistoned Trail that much hotter? The .25 48's are fairly rare. Umarex cleared a few out two years ago and they were snapped up. If you know where one is for sale and don't want it, put a heads up here or on the Dianawerk Collective.
-
Well guy's, I passed on the Diana 48 .25 cal, but bough the mans .25 cal Webley & Scott Patriot. I just got home with it and have fired a few rounds with open sights and hit a 16oz at water bottle at 15 yards first shot have been easy for me. Rifle balance is great in my hands and it does not feel heavy, will see how it performs at longer range soon. yfis dan
-
What is YOUR definition of "plinking" ?
Mine is close range (less than 10 meters/33ft) "fun" target shooting: spinners, silhouettes, animal targets, ice cubes, small crackers and cookies, etc.
This equates to a low power .177 rifle. Low power because at less than 10 meters, you don't need any more power, and low power = easier to cock. .177 cuz it is the cheapest to shoot, as ammo will get expensive when you shoot a LOT.
-
Well I'm going back for the 48 next month as it is immaculate, that man takes care of his rifle he don't shoot the just collected them the patriot was fired only once, the 48 fired 20 times.
He said I had to break the Webley Patriot in first and then tell him what I thought of it, first day with it and I love it, called him and told him so LOL.
-
in period test the .25 48 developed less power than the .22. might have been the relation of the acceleration of the pellet and the short barrel. the patriot/kodiack has a longer barrel, allowing the pellet to reach a higher speed before air prssure dissipation at the end of the barrel. that is the reason the .25 48 was not as efficient. the new crop of .25 available are long barrel guns. the b28, the marauder, the patriot, the rx2, etc... no carbines. the only carbine available in .25 now is the BSA lighting and that shoots in the high 500s, very low 600s depending on the weight of the pellet. Forget long distance shooting with a .25. Even a rx2 i have been testing lately will shoot a under 20 gr .25 at only 720 fps. at that muzzle velocity your effective range is going to be about 40 yards. remember that the trajectory will have an extreme curvature, and unless hold over was your major in college, it is extremely difficult to master and to make it a consistent way to aim, making shooting pass 50 yards a crapshoot more than a skill. But for short range shooting... nothing hits like a 1/4 incher...lol
-
Thanks for your reply, now that you mention it has any one ever re barreled this rifle to See what it would produce in power, or is the piston stroke to short?
I'm going to buy it any way as it is in mint show room condition, I can use it for rabbits and squirrels out to 30 yard. Well in reality I just needed another excuse to add it to my collection LOL it is a looker. I have been learning from every one here and he main lesson I have learned is that every rifle has it's limitations, I will apply it to the situation. I just wished some one had hard data on the ballistics with different pellets I have looked all over and no luck I guess It will be up to me to do it and now I have to buy a crony, but it will be fun. thanks again, yfis dan

I will comment on this, I have spoken to some tuners in the past on the same power plant in question here and have been told that they can be made to shoot in the 750's and up with the right springs, guides, top hats [etc] with 20gr pellets. I have wanted to build a 48 w/LW BBl but just keep putin it off but I have done alot of research on this same matter, even a stock rifle in .25 cal can be made to shoot alot faster than givin numbers but its all in what you want out of the rifle and its intended use. The .25cal is probly best keept under 75yds in a spring gun. I have a 48 in .22cal that shoot respectable speeds with heavier pellets 16gr and up so it kinda hard to make a decision on the 25cal I'm not sure that thier is any advantage to the 25cal that would warrant it in a spring gun other than to say I have one!
-
Mark 611,Thanks for the info and Do you think you can get the information on the spring and specks that made this rifle rise in power? I will be purchasing this rifle for sure just talked to the man he will hold it for me, it will be a great project, yfis dan
-
I'll try to do what I can for you!
-
will give you no increase in fps in a spring gun. Longer barrels will help with PCP and CO2, to a point. All the pellet acceleration occurs in the first 5-7 inches of barrel length with a spring rifle. Longer than 25 (or so) will slow the pellet due to friction. Break barrel springer have barrels that average about 19 inches, which is not for velocity, but to keep cocking effort manageable.

Mark 611, thanks and will let you guys know whan I bring that rifle home to tinker with. Dan
-
Well I was thinking that that might be the reason some of this chinese Clones shoot so hard, longer barrel or so they say LOL
-
HNT5 - 3/14/2010 6:37 PM will give you no increase in fps in a spring gun. Longer barrels will help with PCP and CO2, to a point. All the pellet acceleration occurs in the first 5-7 inches of barrel length with a spring rifle. Longer than 25 (or so) will slow the pellet due to friction. Nathan
Has anyone ever actually started cutting a barrel an inch or so at a time to find out when velocity starts dropping off in a springer???? dunno I am really new at AG stuff and I am sure different compression cylinder sizes would make a differencebut I would find it pretty suprising if it was as little as 7 inches
-
Thier has been a of this research done over the years, they say you only need 10'' of BBl but some say you start to a real fall off when you get at 14'' or under
-
Two weeks back I cut the barrel on my QB36-2 in .22 cal and tested the rifle on a 2x4 shooting from two feet back and it penetrated a little deeper that when stock, rifle It took a chunk of my palm when I cocked as it slipped from my hand needed stitches but you know me I just put a splinter on my 4 fingers pushed the peace of meat back in and walla, it healed real good.
I would say that the pellets penetrated the wood 1/4 inch deeper than when stock. I read some were were Tom Gaylord said that springer absorb most of the energy in the first 10", so I cut 8" of the rifle and for fun the fun, it left the rifle with 11" for the look LOL and it handles easier comes to my shoulder more natural not barrel heavy any more. I Wish I had a crony to really compare the results.
-
Supposedly anything after 10'' slows the pellet down, the reason most rifles have longer BBl's is to aid the cocking effort.
-
Is there a Theoben gas ram for the rws 48?
-
Today I picked up my 48 .25 cal and is is a real pretty rifle, man o man it is spotless. I just shot it a few times to sight it in the scope and took 3 shots and bullseye at 10 yard's.
I will do some more shooting with the Mosquito Pellets, some Diana magnums plus beeman crow magnum and JSB exact pellets to see how it performs, I will need to break it in first, so far real nice shooter. It will be a real pleasure to shoot this fine rifle with my daughter as she loves it all ready, she love to shoot with her daddy. I'm really lucky with my little girl, well not so little she goes to college all ready, LOL.
-
Well had one of my nephews split some cards at 15 yards right down the middle with my 48, mind you this is his first time he ever picked up a spring rifle and as he put it, this is one bad rifle to shoot.
-
I was shooting my 48 today and was splitting some poker cards at 15 yard in half, my rifle came with a 4 power scope not bad for first shooting sessions, will see how it performs at longer distances. I was shooting the webley mosquito pellets.
-
Well boy I got the rifle this Wednesday and it is a real shooter, I just sighted in the scope it came with a 4 power scope seems to be very accurate out to 40 yards so far nice power too.
This is one good looking gun man I love at all ready seems to hit every thing I aim at,
-
38 grains at 596 fps. Thats just shy of 30 fpe. The only air rifles I have heard of before capable of launching .25 caliber pellets to that FPE (in stock configuration) is the Webley Patriot, Beeman Kodiak and Theoben Eliminator. And that is the 'hotter" shooting ones at that. I would think the RWS 48 should be able to produce around 21 to 22 fpe easy enough and there is nothing wrong with that IMO. Anything over 20 fpe in an air rifle is still a thumper.
-
It must be a typo. Eun Jin doesn't make a 38 grain pellet in .22 caliber but they do make a 28 grain pellet. That would be a more realistic 22 FPE.
-
Vortec just came out with a Pro-guide2 for this gun. http://www.Vortekproducts.com
Don't know how well it will work with a .25 cal but you could ask them. They claim a .22 cal shooting at 840fps with 14.3 grain pellets and no vibration.
-
Thanks for taking the time to answer my questions and I will take a look at this link, I have been thinking of the Vortek also, Dan
