Sumatra 2500 in 25 cal with solids?

Have any of y'all played with the Sumatra 2500 series in 25 caliber with solid cast slugs? I'm really interested in these rifles due to their sheer power and reported accuracy. But the 25 caliber would leave me with no local source of ammunition, I'd need to make my own.

I'd appreciate knowing what you've learned about these rifles with this type of ammunition, if you've done any experiments with them.

i have no knowledge of them, myself. as far as ammo, try pyramid air. you can order ammo online and c.o.d. is an option. if you're serious about casting, check out roachcreek's posts. he roll's his own for his condor, and he's damned good at it. that old fart is a wealth of very good information.

I'd have to agree with longhunter on this one. Will Piatt can give you a few pointers and places, people to check as well.



By the way, rumors of my death have been greatly exaggerated.



I'm back . . .

Been a while but I'll be back on the radar shortly. Lots to do yet before I can get back into the swing of being back home.

So, until then, "Hi, y'all!"

of course you have to agree with me, i'm always right .

seeing as you're not dead, what am i supposed to do with the flowers?

seriously, glad to se that you're back home. now, get back to that honey-do list that's been piling up while you were away !

PA DOES offer .25 caliber. Just depends if your mag will accept them as they can be quite long.

Then there are guys like Mr. Hollow point (Google him and he'll pop up there some place.) I've heard of Jerry slugs but when put to the test he refused to sell them to me for a report on them---there were a couple of complaints about them as well. But I can't say that they are good or bad since he wont' turn loose any to me for my own observation.

Besides, it's not the solid cast that does the trick: It is the weight to FPS factor and, then, of course, accuracy.

Just MHO. You can buy cutter slugs that will give the same effect as an unskirted round. Diablo or "wasp" style is there for a reason. You'd need a lot of twist in your barrel to stabilize the shot.

Have you really thought this through to more than posing the question?

there's aguy who goes by subsonic that casts slugs specifically for the sumatra. i think he gets 93fpe out of his and good hunting accuracy. he uses an lbt mold from veral smith, just like roach's but i think sized different. he had an easier time getting them to shoot i think because the sumatra barrels aren't choked like the lw

Got a link for this one, Griz?

Seems my RSP endeavor using a .22 Rainstorm (old style) converted to .25 is a no go. Instead we are going to use the .22 infinity. Hate to give that one up for it but my Rainstorm is a .22 and working perfectly (need to tweak the tension on it as it's not advancing at the moment) They use the same action as a Dragon Slayer so this ought to do the trick to get a good---and unique--- .25. I'd been using those Eun Jin .22 32.4 grain but main, I tell you, it's got the same ballistics as a rim fire, affraid to shoot it too much round here without a definitive back stop like a solid tree or something. Rips the guts right out of the squirrels.

By the way, my war on those tree rats are in my favor! After taking out and culling them down 'round here I had my cousin come up from Tallahassee and take down some trees. We joke about I26 and I95 being cut down now (two major highways in these parts. Most know that they have "routes" they use and I've cut them down! More sun light for the grass and future garden in the yard now and, by golly, if they get into one of my trees they are stuck on an island! Like fishing in a barrel!

So, I'e got two RS's now and I'm going to send in my Infinity to Will and we'll start over with this one. He's figured a way to make it work with a .25 round. Problem was with the RS that we couldn't get the RS to accecpt a .25 round mag---just not enough meat there to work with in metal.

By the by, anyone heard from Tom? (Orairgunner)He's got a slow connection and busier than a beaver these days.

Anyway, got a link for those rounds you were talking about? I think with the kind of power I can put out with the Infinity that those solid slugs my just be the ticket with this new match grade Walther falcon barrel we are about to put on it.

Stay tuned, I'll keep you informed about the project. Probably won't bull pup it though because of the safety issue but then at least I'd have a killer .22 and and better killer .25 (my goal) then later get the newer 9mm Evanix and then I'm done. I had the .45 and it was just too much with to little of a follow up round. (what a powerful AG!)

Well, I've got things to do still yet to shake off the road trips I've been on.

Glad to see you guys (or write to?)And AWFULLY glad to be home again!

Stay in touch.

-Will

P.S.
Remember, we don't care here if links are from the Talon or what ever. As long as it is good info, it belongs here!

I've been watching, nobody has been naughty. Regards, Tom

Ur such a BAAAAD boy, longhunter. Stir sumth'n up, would ya? I'm not here much here of late (and that won't last for long) and we could use the controversy and debate *good honest stuff now*.

Anyway, update on my RSP. Didn't work. Not enough meat on the RS to accept a .25 mag.

SO . . .

Keeping that one and put's me at 2 RS now. One with the longer tube---don't let anyone tell you that extra few inches doesn't make a dif . . . it does!

So, we decided to go with my Infinity .22 to a .25. Shold get much more power out of it and it's already got the CF shroud on it (mine from a previous upgrade). I just sent it back off to Will yesterday. Can't wait to get it back. It should take some very heavy and solid type ammo as well.

And the saga continues . . . on that one anyway.

But I'm about to take out again. I won't be here for a bit.

Thanks all for keep it clean around here. Couldn't ask for more!

Again, thanks to Tom as well.

Later all!

i got to thinking, then i got a headache. are we overstabilizing our pellets-slugs with too fast a twist? if you'll bear with me, you might see where i'm coming from. ( or you'll get a headache ).

if you take a look at muzzleloader velocities, and projectiles, you'll notice a similarity between them and airgun ammunition. the optimum rate of twist for a roundball is 1 in 72 in. the mv. is , if i recall, around 950-1000 fps. the optimum rate of twist for a hollowbase " minie bullet" is 1 in 48 in. with a velocity of around 1050 fps. both are in the subsonic to transonic range.

the minie bullet is the closest to our frame of reference. when fired from an 1863 springfield rifled musket, it was an extremely accurate round.

why then, do we insist on using 1-17 and faster rifling to propel a sub to transonic, wasp waisted, drag stabilized pellet? wouldn't a twist rate of 1-20 or 22 be more effective? the same could also be said for cast or swaged bullets, so long as they were being propelled at subsonic velocities.

just trying to stir the pot, while abda's away .
