25 cal Sumatra 2500, 25 cal with a Seneca barrel
« on: March 09, 2021, 01:13:55 PM »
So, alot has happened in the last couple years concerning my air rifles but, I just haven't been in the writing mood...so, this happened: I left my LDC attached to my Sumatra 2500 in my family room for a couple of weeks and somebody knocked it over and got the end of the barrel bent (of course nobody did it...I was mad) fast forward two months later and I took it to the master,, Will Piatt and it was sooo bent, he couldn't straighten it out.... so we tried to find a used Sumatra 2500 Barrel but to no avail....so I had to order a new Barrel from pyramydair which thank God they had it.. BUT, it took a few months to come in as I  had to wait for the ship to come from overseas (madness right?) So, altogether it took about 7 mos to get a barrel for my 2500...FYI, Seneca barrels are longer than Sam Yang and (I believe) tighter.... I said all of this to update everyone on my 2500 and to ask any Seneca owners out there, their opinion on the best pellet for it..... I'm still using the 34 grain jsb MK2 but I was just wondering if there is anything better out there for a Seneca 25 caliber Barrel...Thanks...Oh, BTW Will is genius, he altered a few things and fashioned a few pieces to make that longer barrel work

Ok so, the barrel shoots MKII great just like the original barrel ...so, now I want a slug to shoot for hunting season so, I measured the MKII's OD and got .254 repeatedly....My question is this ...how are people getting good groups with .250 and .251 slugs???? Most times I can't even get these to stay inside the magazines (slipping thru)....can somebody tell me what I'm doing wrong....I really wanna shoot slugs....

Ok so....this is a testament to "time behind the trigger" ...back when Nick NIelsen was getting started up with his magnificent bullet bizz, he sent me some samples...I still have these samples because (in hind sight) I didn't know how to set up my rifle to shoot them ....

Have you slugged the barrel yet? My Sumatra is about 2 years old and it slugged out at .2515 so I size to .252 and they shoot great. I also found that varmint knockers that are sold on flee bay work very well as received.
