Just pulled the trigger and got the maverick vp. Now in order to shoot slugs. Not heavy slugs but 25g. Do i need to change barrels or get liners?

The standard STX Superior liners can do well with light for caliber slugs. The heavy liners are really only useful for the heavy slugs.

My Maverick .25 shoots very well but have never found an accurate slug for 100 yards. I converted to .30 and it's great!

In .177 i see practically no difference between std barrel and Heavy barrel when it come to 13 grain slugs or lighter.
In this caliber i will call 16 grain heavy, but some do have success shooting those with a heavy barrel, but that is not my personal experience, i had to by another brand rifle to be able to do that.
I have just shot 10 grain slugs, quite enjoyable out to 120 yards, and i am not talking barn door size targets, really i prefer to shoot 2 inch targets, but that day no targets just things down there like thin posts ASO
I was quite amazed and promised myself that i better restock some of the 10 grain slugs CUZ i am now out of those.

Suggest you look into the Easy tune system from Shooting with Phil. Soooo easy to tune my Maverick.

Just posted this at Phil original post.
Thought it might interest you!
Just a new piece of info for you. I was having trouble getting consistent strings without 1-2 high variance (20 fps )shots. Also was getting some creep in 2nd reg of 7-8 bar from 78 bar to 85-86.
So I went back and checked the front reg and found issues-
The front reg had a bad oring which I replaced ( I thought it was set for 150 bar!). Actually the bad o ring was allowing the full 250 bar to “press” on the 2nd reg, causing creep. I also thought it would be better to have less pressure on 2nd reg so I re set the first reg to about 40 bar higher than 2nd reg.
Bingo! All issues were fixed! Get 2-3 bar creep now but the std deviation is 1-2 fps and there are NO unusual, big jumps in the shot strings. I finally see what you are getting!
Thanks for this innovation

Your going to want a heavier hammer for running over 18gr pellets or slugs . The fx .25 cal hammer weighs just over 13g works great , in the .22, for ammo over 18g and is the only change needed imo . The factory 11g hammer works good up to18gr. I've been down the slug road and the AEA or JTS pellets are far more accurate and less expensive to shoot. I could get some dimes at 50 with slugs but not consistently . Even with a low SD. I would suggest getting some pellets and break it in while getting a good understanding of the adjustments. Then try slugs .
The best thing I did with my .22 vp Maverick is tune it well for 25.3gr AEA pellets and leave it alone. And a 300cc cf bottle for a handy 6lb 11oz . I'm also running the slug port and getting around 2 fps standard deviation. Here's a short string .

You’ve read my mind! Getting a heavier hammer soon. Also already ordered some AEA pellets so I won’t have to weigh and sort the FX and JSBs to the nearest .1 grain!
Don’t mind the sort issue as I’m retired, always looking for something to do!!
The charts Phil has made are spot on for me now with lighter pellets. Have you tried lighter slugs?
I am hoping for much heavier pellets in .22, too. I think AEA sent some 28 grain ones.

Ty for the replies. I have the .25 version. Just recieved the easy tune with phil. Waiting for chrpnograph. Took the barrel off over the weekend and found out it was shipped and tested with slug port from the pellet shop. Have been shooting the hades and neilson slugs 25/26 grain. Been accurate so far up to 50yds. Slugs and pellets. Slugs past 75yds kind of all over. Havent tried pellets.

Hi Firewalker. What 30 cal slug(s) do you find to be accurate at 100 yards? Brand, weight, velocity? I'm just always curious about other people's experience with 30 cal mav and slugs and the accuracy.

I have shot the H&N .27gr HP2s around 960-70 with great success from a 600mm superior liner.

I've tried numerous pellets to 100y and they all did OK, that's fine but i wanted repeatable accuracy in all conditions so I tried NSA 49.9gr slugs and my Maverick just loves them!
No, they are not MOA, more like 1 MOA at 50y, 1.5 MOA at 100y and 1.25 MOA at 125y but they are precise, groups do not open and no fliers.

Thanks Firewalker. Nice! Is that with the 700mm 1:22 twist liner? What muzzle velocity?

Holy cow! Only 850 fps? This is giving me a whole new perspective. My 30 cal mav sniper is the only pcp I've ever had and I'm strictly a slug guy. I've got both 1:22 and 1:18 liners. I shoot 49.5 nsa with the 1:22 and 54.5 nsa with the 1:18. I've always tuned the mav to shoot slugs FAST, partly because I was initially power-hungry and partly because I had the impression that slugs needed to go fast in order to be accurate. So your experience is making me realize that, although the mav can put out some really good power (I'm currently shooting the 54.5 gr nsa at 961 fps -- 112 fpe), the mav can also be accurate with slugs at lower velocities and get more shots per fill. And less recoil to deal with at those lower power settings (it's a tiny amount of recoil, but still present).
I've got about 1500 rounds of 54.5 gr nsa and no 49.5 nsa at the moment. You really have me wondering how far down I can go with the velocity of the 54.5 gr nsa slugs and still get the kind of accuracy you're getting.

Now, before you go and change everything, keep in mind my goal was accuracy and precision only, not penetration or expansion.
I will hit whistlepigs and bandits with this but not coy-dogs.
I chose 850 and worked the hammer weight and Phil's hammer adjustment for precision and the best accuracy as a second goal.
Can I do better at faster speeds? VERY possible! I was delighted at the precision and stopped there!
Also, pellets seem to like this speed too.

A slug will be ballistically superior to a pellet at any speed. Most people like to push them fast to take advantage of the better stability a slug provides. There are some cases when you might need to push a slug faster if your rifling is on the fence of rpm stabilization. But other than that specific scenario, there is no advantage of accuracy in regards to fps. Time of flight at longer distances might bite you in the butt on a windy day I suppose. However I will take a slow slug over any pellet when I can. I have a Maverick compact I built in 30Cal but havent tested it still. Hopefully I can provide some numbers soon.
