Has anyone ran slugs in the .25 cal. 250z yet? If you have what size did you have luck with? Thanks.
Barra Slugs in the 250z

Totally understandableI promise I will try some more slugs and probably port some things on my 250z. I’m just waiting until my replacement stock gets here from Barra. I screwed the factory one up trying to install a side folding adapter.It’s kinda hard to shoot a stock less gun.

That's why I didn't touch my stock, I was worried about screwing it up, and I have way to much time into mine to risk it.I promise I will try some more slugs and probably port some things on my 250z.

Best advice you can give, I really really dislike the "TRY 100 different ammos" method, it gets costly, and disappointing, gives me a sour puss on my face lol.

Take a measurement of both ends of the barrel, breech and muzzle end with a caliper, buy a slug that is as close to that measurement as possible, push it down through the barrel , breech to muzzle, measure that once its come out.
You will still probably have to try different slugs but youre going to get as close to the correct diameter projectile that you need before trying different rounds.

I just take a slug and squeeze it in a vice to bigger than the bore.. The tap it into the bore with a rod... Run it in the 250z case, all the way thru the barrel and measure..

Sorry if you’re seeing this again from HAM. But I figured I’d share…
Okay so I finally took a picture of a grouping today. I switched to 36gr custom made Franco slug from 35gr(cuz I’m running low
). They look most like NSA cup base hollow points.They are really really nice slugs and they are very affordable… anyway I had to tune slightly with a reg bump and tune. Reg set right at 2500/2550. Hammer spring about 1/8th turn from flush. *I have the slug power kit and thimble valve ported to 4.4mm…
I did shoot this off a tripod but not in a rigorous type of way. I shot this kind of fast and in very windy conditions. Mostly because I’m impatient haha and I’m a hunter I never get perfect conditions while chasing critters. My range is in a slightly less windy spot but it’s still not nice out there haha.
Anyways this is 7 slugs from 45 yards. Measured with laser range finder.
Don’t know the FPS because my chrono is loaned out to a friend haha but I’ll find out this week. I did shoot at a squirrel earlier at 114.8 yards(I’m a nerd y’all! And got gifted a rangefinder recently lol) and missed low. I wasn’t holding over at so like 6-8 inches of drop at that range. Either the slugs have a great bc or they are moving at decent speed.

What's slugsdo you recommend on .25 with rogue slug kit which I will be installing this weeek
Upvote 0
My .250z likes them all to be honest but my recommendation is to stay around 60-65FPE…. That’s the sweet spot on the gun. At about 2600psi I’m shooting 30gr Franco slugs at 950-960 FPS. Super accurate and I’m getting 20 shots a fill. At the current settings it will also shoot 35&36gr Franco slugs at 860-870. I like the 30gr because they are versatile. I shoot birds all the way up to coyotes with them. With the smaller game the heavier slugs sometimes overpenetrate…. But ultimately it depends on what you want to shoot and how far.
Also with the slug power kit you need even less hammer spring preload. The weight of the hammer weight opens up the valve just fine… but the hammer weight will 100% give you great accuracy adjustment. I’m about 1/8 turn pass flush right now. This gun will shoot almost any slug in dime sized holes at 50yards if you fine tune it right.
If you go to Instagram I have scope camera footage of my barra in action filmed yesterday and today. For now I’m pretty much set on these 30&31gr Franco slugs going around 940-960. They shoot very flat and the expansion is unreal. Watch how that squirrel gets slammed at 63yards

im gonna try with HN 30 and 36gr .249 and see from there just ordered...right no im just shootgin jsb 33.95

I wouldn’t go .249… I’ve used .250 and .251… and chrono numbers I get have been better than a lot of the review videos I’ve seen where they are testing slugs. Slugging your barrel is the best choice of course. But getting a good seal around the slug gives better performance. Cup base and dish base both work great. I think cup base slightly better…. The Franco slugs I use are most like NSA slugs.

Sorry, I have been super busy with planting and other spring work lately. I did put a new stock on it a bit ago, but have not shot much lately. I did get acceptable accuracy with the H&N slugs I tried. I need to get a cronograph before I can do much more testing.

I'm going to try with .250 now, tried 30-36gr H&N .249 reg about 2600 hammer spring just wnought to have variation of literally 1-3fps shooting 30gr at 934fps and 36 at 895fps.....36gr shot me better but it was a light windy day. Now gonna try .250 and see how well it does....what's your fps on 34gr .250???
I do have now rogue hammer kit and works fabulous

I only ever got the 34gr H&N slugs going about 860fps. But that was when I was just learning how to set the gun up as this is my first pcp… since then I’ve shot the 35gr Franco’s at around 895-900… but I like the 30&31’s the best. I am noticing that passed 100y they are drifting more than I like so I will probably shoot 35gr on those days. But having shot a variety of critters with the slightly slower slugs I have to say the stopping power of the lighter slugs going faster is better. It’s actually the same FPE on the math but when the lighter ones hit they really dump energy.
I didn’t understand what you meant about the hammer spring. How far do you have it turned in? You can use the hammer spring to tighten the groups on those lighter slugs

Are you shooting targets at 150y or hunting? I agree that the 36gr don’t move as much in the wind but I think the stopping power is worse. In fact I know it is. The 35/36gr tend to pass all the way through squirrels and rabbits even at 150y.. I shot two squirrels today one at 75 and one at 74 both in light winds. The 30’s just expand better and I never get pass-throughs.. turn the sound up on this video. This is 31gr Franco slug, 950fps at 73.8y.

Can you expand on the measuring part? The slug would have rifling marks, would I be measuring the widest part of the slug? Also when you squeeze in the vice are you clamping on the base and tip to make it shorter and fatter? Thank you. I’m very new to the slug game.
