Who’s shooting them & what kind of accuracy are y’all getting? I’m looking at getting some for my .177 syn rod. I haven’t found a pellet it likes yet out pass 15yrds. So I was gonna try some slugs out of it. At 15yrds I can get a single hole with 10.6 kodiak match but even at 18yrds it opens up to an 1”. Pellet flight is crazy at any speed. Ive done some valve work & ive got a double wound hammer spring for it. I’ve had the 10.6gr up to 1250fps before. So I’m thing maybe go with a heavier slug & see what’s happens. Also do the 21gr slugs fit the mrod magazine??

You are shooting way to fast. Slow it down to pellet speeds and it will shoot just fine.

Asw far as .177 slugs in a mrod I have had best luck with the ones under 21 grains, inch or so @ 30 yards, ok for busting a bunny perhaps.

Anything above 860 - 880 in .117 is asking for bad accuracy.

I had good luck out of the .177 Prod, SST with the 21gr slugs, about 900fps, at 50 yards w/thumbnail size groups. 100 yards a bit over 2.25" group.
All shots were tethered to a bottle, regged 3k PSI.
If I could get them to go faster I think my groups would be better at 100 yards. Also if I polished the barrel and sized the slugs that would help as well.
15gr slugs sucked at 25 yards for me, so I stopped there with wasting any time on them... Also if you can get the piledrivers to +950fps they should shoot great as well.

I should have put in my OP that I’ve had it any where from 650-1000fps. And no FPS made any difference in pellet flight. I even had the barrel re-crowned.

It is starting to sound like a barrel issue.

I think I would give Crosman a call.

Think it would be a waste of time calling crow man? I bought this thing a few years ago & had the it re-crowned to try & fix the issue.

I'm with the other guys, I'm thinking barrel issue here. I'm assuming you've tried the heavier .177 options like the 13.4 and 16.2?

As far as the slugs are concerned, I've been able to get really good accuracy out of all three weights. I'm using a LW unchoked polygon barrel. They all do pretty well over 900 fps, but all the weights really shine at 1000 fps+ for me. I'm talking targets at 100+ yards are a cake walk. I've even hit targets well past 150 yards with the 15.5 and 18 grain. I haven't tried the 21 grain at those distances, since I only use them on the highest power/low shot count tunes.

same here Donny,
my at44-L shoots NSA 15.5gr hpfb slugs very well at over 1015-1025fps
with the factory hatsan barrel that has the choke removed.

i dont know why people say it can't be done

How did it shoot before the valve/spring mods?

KnifeMaker · « **Reply #11 on:** March 24, 2020, 11:22:23 PM »

Some how I skipped a word. It should have read anything over 856 to 890 is an issue with PELLETS. Faster is usually better with slugs.

Just waiting on NSA to start producing them on the High Speed machines. When we can get 400+ .177 slugs for @ $19.00 similar to the larger calibers we already can off the high speed machines I will dive in head first !!
Have the guns capable of 1000 fps +& have barrels and the other required stuff to go small bore sluggin !

That time is coming real soon! I've already tested some off the high speed machine, but he had to get a piece of the tooling for them remade, and I don't think he's settled on the final weights just yet.. The best I can understand, we are a matter of weeks away from low cost .177 slugs

Just in time for SPRING TIME ground squirrel shooting !!!
Will keep watching his web site on the news of them being ready

I'm just minding my own bidness when this thread had to come along, and then that Hatsan build of Donny's popped up in my head.

I should probably focus on a .22 slug-gun build but .177 is Just More Appealing

It shot the same, no difference after the mods.

Also I called crosman & ive got to email them the serial number off the gun, state my problem & wait to see what they say. But they’re not shipping anything right now die to the virus.

I’m actually thinking about the poly rifling barrel from lw. But we’ll see what happens.

I'm pretty sure LW is still shipping barrels

Of course, then you'd have to get that one machined.
