Interesting but nah. I can get small CO2 carts at Walmart. Don't imagine shipping on the already pricey Nitro is cheap.. BUT anyone have any idea about if they made a Semi or more auto version itd make sense? Cause CO2 gets all cold and fps drops off due to expansion etc but if nitrogen is more...

Yes it is a lot of trial and error but if you look around on this forum or anywhere else I'm sure someone will have some suggestions for sizes for the .25 cal No I didn't measure the slugs myself, just ordered from NSA and shot each size and recorded the results on the target. The target was 10...

Yep mine had both indents one for each grub screw. I also like stuff tight and always have to catch myself from over doing it. Apparently the .25 cal is worse offender as it's barrel wall is thinnest

Welcome to the forum! It is all about accuracy. Your barrel is a certain size and if the slug is too big or small it will open up your groups because those need spin to stabilize and be accurate. Most of the time slugs need to go above 900 fps to spin quick enough to stabilize too. Also the...

The indent might be from an over torqued barrel retaining grub screw since it is at the top and doesn't follow the rifling as far as I can see. When I pulled my barrel last I saw similar thing but same here it shoots pellets fine and slugs too so I guess the pellet or slug gets fixed by the rest...

Glad I can help! Just know I've polished and crowned my barrel and also done a bunch of other stuff to my Avenger but that should still get you in the ballpark for the slugs, like you know probably don't get .217s and that the slugs like the high speed.

Literally saw the NSA sale and thought same thing for my Avenger-gotta stock up! haha I actually just tested out some NSA in both weights and sizes you mentioned. See this thread Basically because of the rifling contact on the short 17.5 you wanna try slightly larger than the 20.2's I shot...

Makes perfect sense! I ordered some more 20.2 gr in .216 and threw in an order for .2165 just to see if they will work any better. The .217 in 20.2gr is a shotgun pattern so I don't have high hopes for the .2165 20.2 but I'll see. On a side note I measured the rifling in my Avenger barrel at...

Thank you all for the replies. That's a very detailed video and I'm glad to have watched it. I do not have a micrometer, just digital calipers. But I do have a target and the ammo so I set it up at 30 yards and tested the ammo as suggested. As shown but just to clarify: top row left to right...

Copy paste of what was said above. I don't buy pellets from Pyramyd not cause they're bad but because their markup is nuts. Even with the buy 4 get 1 free AND a coupon, Trenier is STILL cheaper almost every time. Only downside to Trenier is they don't have every brand like H & N.

Another vote for Trenier. Very well packaged and quick email replies and shipping.

Interesting, I thought slugs needed very good contact with the rifling in order to be stabilized and be accurate. You think even the .216 may be too big? Can you please share why that is? I am trying to learn the most I can! I only just sat down at a bench yesterday and rough sighted in at 30...

Hey guys, I just slugged my Avenger barrel. I have polished and put a crown on it previously using @nervoustrig methods and just now opened the barrel port to 5mm and installed a weaker poppet valve spring and use a heavier hammer spring. Took some photos of some ammo I have and yes I...

Scroll up slightly and see post #77. It is for sale on ebay
