Thanks for that! I've talked to him quite a few times in the past. I'll check his thoughts.

Dillon,

REALLY high BCs on those heaviest .177 NSAs.

Thanks Cole! Bob did point me to it. That's some crazy accuracy and BC! For those puppies I'd bet I'd need an even longer barrel than the 20" that the normal .177 Prophets come with. But man I would love something like that!

Just got the RTI Prophet Performance .177 and it is very accurate with slugs 
Planning on adding a 600 mm LW polygon barrel

Ok now that's good news! May I ask where your reg is set at? Trying to see what kind of power is needed for that. I wouldn't think too much.

Just curious SorenSD, if your gun is very accurate with slugs, why do you want another barrel?

Regulator set at 135-140 bar and hammer spring tension is flush with the buttstock - 925 FPS - 25.52 FPE

Not sure that I am going to update - Did a clean and a light polish with Autosol and that improved the barrel a lot !

Could be because the .177s only come in 500mm? All other calibers are 600mm in the Standard length.
Edit: I see he posted his reason. Good to know also.
And thanks for the info on the reg! I have the plenum on my Compact already, but looks like I'd need to have the full length barrel rather than compact barrel to keep reg pressure not too high. Shooting at 110bar and 28fpe in .22 right now. So more to think about on that as well....

Out at my private range in the country today after work. It was a little windy and the wind was coming straight at me.
I am still very happy with the result at 100 metres / 110 yards !
RTI Prophet Performance .177 - JSB KO 13.43 gr slugs - 925 FPS - 25.52 FPE

110 yards is getting out there with a little 13.43 out of a pellet barrel. I’m impressed. I was thinking you probably had your reg around 140b and it’s nice that your hammer screw is still only flush. You should still have a little free flight on the hammer at that setting. Nice shooting.

Well today I got a 510mm .177 barrel for the RTI. Have 13.43gr Knockout here and 12.5gr NSAs on the way. So guess I'll be playing with a .177 slugger after all!

Well, I have my “little” Uragan Compact coming. I thought it would be worth the time to try some slugs in it. Here is the following which will be tested.
- Precision Ballistics 10.4 gr. Makos - 2 types (1 is prototype)
- NSA 12.5 gr.
- JSB 13.4 gr. Knockouts
- JSB 10.05 gr. Knockouts
[/LIST=1]
It will be a bit before I get into messing with the slugs at an in-depth levels. Need to know the gun and go from there, I have faith in the CZ barrel.

In a recent discussion with Franklink, it was mentioned that Zan made some 20ish grain 177s. Since I've become a little taken with the NSA's, I thought I would search for some today. Zan lists NO 177s on their website but Krale has 3 offerings that are out of stock.
Anyone know anything about the Zan 177s ?

Here is what I got out of Shadow, my Uragan Compact) today at 50 yards using Precision Ballistic 177 Mako slugs. Shadow’s CZ barrel isn’t supposes to like slugs sees to like the British food.

Has anyone had any luck shooting slugs out of an R5M? Don't see why they wouldn't work, just haven't started yet

I built up a little 177 slugger from mostly Benjamin and Cothran parts, Magnum valve. Not had a chance to get it to the range yet, just too windy, but in my garage range of about 30 feet, it will make 42lbft with the NSA 20.5's. The groups tighten up a bit with NSA 15's or JSB monsters. All groups are clovers but the 15 grainers just shoot a bit tighter. With a light pellet it will push 1300fps. And this is just with a cheap 24" Crosman barrel. May be time to put a "good" barrel on it and see what it can do. It could certainly use a faster twist for the heavier slugs. And a heavier barrel not requiring barrel bands could "float". Hmmmmmmm

We are currently experiencing bipolar weather here in Southern Oregon, and I missed out on a couple of decent shooting opportunities (sometimes work gets in the way). Today was by no means a perfect day for shooting, but it wasn't raining, so I finally got the chance to try out my Zan .177 slugs that just came in.
I received the 10g, 13g, 16g, and 20g. I shot them all, and since the JSBs shoot excellent with my gun, I compared the Zans to the JSB 13.43g as a baseline.
There were swirling winds and I had to pick my best opportunities, so at best, this is a screening test. I was shooting off a Caldwell Fieldpod, and I was making a reasonable attempt considering the conditions; the results show great promise for the .177 Zans in 10g, 13g, and 16g. I am sure the 20g would do better with a greater FPS. I typically do not "tune" my guns. If I get decent groups using the hammer spring adjustment alone, then I live with that and try projectiles that work within those settings. I was at hammer spring 5 for all shots, including the 20g, where I also shot at Max, so there are 2 groups for the 20g.
You will also see a heck of a flier on the 10g. That was shot #1 where a gust of wind came up just as I pulled the trigger, so it's obvious that the gust was active at the target, so I didn't count that one, and there is a hole in hole on that target as well.
I'll post pics once the site has uploads working again.

As the pictures show, the JSBs don't look as outstanding as they usually are at 50 yards, but again, it demonstrates what the Zans are capable of on a better day.
