EVOL Tuning the 15”. Help from the pro’s

[Madeintheuk]

alright experts. As being as I have some time waiting for Tom to get back to me, I guess I’ll play with some tuning. I’d like to primarily shoot the howler slugs, but I’m sure a similar tune will work for heavier pellets too.

What are your settings if you’re shooting similar ammo? And what velocity did you find shot the tightest?

Thanks in advance.

I sold my 15" last year so trying to remember some of the details.

I remember trying the Howlers and the NSA equivalent. I slugged my barrel out to .218 or .2175 - it was pretty wide. Mine did better with the NSA in .218. I believe I had set the reg to around 2200 psi and was able to get them easily into the 920-950 range. I would do just okay groups at 50 with them (maybe around 1") on a clean barrel. The barrel would foul very quickly, ~100 rounds, with slugs and cleaning would take 10-15 heavily darkened pull throughs.

Now I recall a video maybe 2 years back where Dana was using the same gun (can't recall NSA or Howlers) and his was doing hella better at 50 and 100 with the same approx slug speeds than mine.

I'll be watching to see how it works out for you.

It will probably work out as well as it did for you… Buying pellets guns to then try and make them into sluggers seems a fruitless endeavor for most. Why not simply use the platform as designed? Or, move it along for a true slugger, maybe a .22 rimfire…

Seems like you will have to simply lead on this as the base of Evol users “tuning” is probably miniscule. Looking forward to what you ultimately settle on…

Pretty much where I am right now. I've spent 4-5 years trying to get a stupid slug to shoot out of a pellet barrel. You'd think I would give up too. The BRK Sonoran just chunks MOA groups @ 100 yards with the .30 SubMOA barrel and 'pellets'. Of course I had to just order a few slugs to try and nope - couldn't even come close to pellets. Good enough for 100 yard shot at a medium size animal, but not MOA.

Grab a Huben K1 in .25 and you can sling Altaros slugs near MOA @ 100 easily too.
The Mora will do it with slugs in .25 easily.

Or you can, cringe, get a Panthera or something FX and have no trouble buying the right barrel for whatever slug you want to shoot.

I have a buddy with a drs pro and a panthera he is looking at selling. If you are wanting to go that route.

I would hold off until you can get an actual slug barrel. I did a thread a while ago with a ton of different slugs, and couldn't really get any of them to shoot. Most of the rifles now are pellet rifles, sadly.

But why sadly? The promised slug shooting barrels will eventually arrive, or not. But if the pellets are gittin it done. Why the sadness…?

I own a 15" as well as my brother. We both shoot slugs only as we are hunters/pest shooters not target. Here is my best advice.

Ditch NSA and howlers, the juice just isn't worth the squeeze. We've never got them to shoot consistently accurate and they don't expand very well. RMR hybrids, patriot javelin 21 grain and Griffin LDC or tapered hollow base in 21 grain all have done exceptional in our barrels with a slug tune. When I say exceptional, I mean around an inch or less at 100 yards.

Here's my tune
Reg at 2200-2250
Patriot javelin.217 21 grain at 950 fps for 40+ shots
SLUGS LUBED WITH SPARTAN ACCURACY LUBE.

I bold print that last part because that has seriously been the ticket to CONSISTENT accuracy. No more fouling. I haven't cleaned my barrel since(around 2k rounds now) I've used it and accuracy tightened and fliers disappeared. It practically eliminates fouling. Hope this helps.

A lot of guys have said that the 15 shoots slugs very well. In fact, Dana did a video on it shooting the howlers and the groups were astonishing. I don’t mind too much playing around with tunes. I’m just looking for some advice on where to start. Those that haven’t owned, or don’t own one need not respond. Thanks.

I keep trying a new slug in both my EVOLS and Paradigm and now I'm going to wait for Tom to have the drop in subMOA barrels available for purchase. Talked with AoA the other day and they thought the barrels (and the new HP guns) are within "weeks" of being available.

I ordered another plenum extension and will have one in all of my AAAs now and am really enjoying the external adjustment that Derrick installed in my Paradigm.
