I just did a full tank string of 120 shots using the sorted FX 25.4 25 caliber pellets. The first 91 were all the 25.2 weight group and the rest were the 25.1 group. Wow, what a difference I am no longer disappointed with the consistency of this 910 fps tune! I've attached a chart of the...

I just sorted the last 303 FX 25.4 grain 25 caliber pellets from my last tin. I'm attaching the chart FYI.

I guess the good news is that my Avenge-X tune is not so bad after all. If I write off some of the sharks teeth as inconsistent weight variation it would look a lot better. Here's the graphs of the full 115 shot string and then the first 100 where the tank pressure started dropping below the...

Does anyone have any experience sorting FX brand .25 caliber 25.4 grain pellets. I have just been tuning my Avenge-X for these at 910fps and got pretty good results for a whole string of 100 shots. However, shot to shot deviation looked higher than I wanted. So, this morning I sorted a bunch...

Previously, I had tuned my .25 Avenge-X tank version using AEAC Steve's method for JSB 33.95 MK2 pellets at 870 fps and it worked very well. Now I am playing around with JSB 25.4 grain pellets mainly to get more shots per fill since I am only shooting paper. I went thru a tune using Steve's...

More Avenge-X regulator questions: nervoustrig, in your post regarding making insert out of harder delrin, how did you cut out the new inserts out of .04 plate? I was looking at maybe using delrin round stock and parting them off. Back 50 years ago I worked as an N/C machinist for the...

Thanks nervoustrig for the link, lots of info there! I should have been able to find it myself, but apparently I didn't hit upon the best search terms. For now, I'm just not going to worry much about it until I check out the accuracy of my tune. So far I've just been checking fsp spread and...

I have a .25 cal avenge-x tactical bottle version and have been shooting a lot of full strings while tuning. I have noticed a gradual regulator pressure drop as the bottle pressure drops starting around 3000 psi or so. Searching these forums, I found that AEAC Steve says this is normal for the...

I realize this is a pretty old post, but in case someone is still following.... I have a .25 cal avenge-x tactical bottle version and have been shooting a lot of full strings while tuning. I have noticed the same gradual regulator pressure drop as the fill pressure drops starting around 3000...

I would also, however it is almost impossible to get in the USA. I just received 8 tins of the 25 grain pellets from Pyramyd Air, so I am going to start over with those. I want as many shots per fillup as possible as I am only shooting paper. I'll do more tweaking with those. I am currently...

c88machining on ebay has the plenum that I purchased. I'm thinking about the .22 barrel myself but then I was watching AEAC Steve's video. He said the .25 was easier and more accurate so I have not done it yet. What tank are you using for the tethering? This is the plenum available on ebay...

I recently purchase the Tactical .25 caliber Avenge-X Bottle version and have run through about 2000 JSB 33.96 MK2 pellets while playing around with tuning. I have been using Steve AEAC's method and have gotten some excellent results. It seems that with his process, you end up with the optimum...

The only real comparison I have is that the "850" tune from Steve I had 175bar regulator and about 5-1/2 hammer spring. With the extra plenum and heavier spring I have regulator at 155bar and so far the hammer spring at about 3-1/4. It's giving me 860 or so fps. I'm not sure I have it dialed...

In addition to the plenum I also am using a heavier spring from Ebay.

The good thing about the FX Pocket is the IPhone app that lets you look at the shot string graphs, etc. Try backing the hammer spring out all the way and go 1/4 turn in at a time to find where the fps levels out. You should then be close. Have you watched Steve at AEAC's tuning videos? I have...
