Is it just me, or do you others find that the sig is prone to surface rusting. I'm finding that if I don't oil the barrel nearly every time I use
it the surface rust appears. Also had some show up under barrel seal.
I'm hoping that eventually it will stop with oiling.

I found on the gamo the bipod was actually really good for standing shots. It gave a much better grip when legs were folded back. Never any good of my table.(but that was pre barrel change) Think gun was to light and piston hit to hard.

Blue ring is 40mm so same as aperture in standard field dropdown targets. I will have to sharpen up for 50 metre range at the club.

Bipods - No regrets but I would not fit them to another break barrel, prefer to spend money on quality rest or bags. In this case I am shooting against PCP owners and ready to try anything.

Less to carry so they can improve setup time for almost anything else being shot from a bench or other flat surface.

I use Gamo bipods, I feel they are a touch wide but stable enough.

Fitting the rails was tricky as no room for nuts on inside so only threaded into the stock and screw length had to be exact.

Obviously they make cocking a little more difficult but I have that sussed.

Stoeger pictured below, these looked interesting but I could not source, Airgun Detective site has incorporated some good ideas into his own shop version which he had installed during ASP20 video review.

How big is the blue circle?
You got to be happy with that, that's a nice center hole.
Whats the bi pod? I've got a gamo one but are a bit wary, it never helped the gamo. That target tells a differnt story about them. 👍

Checked tin and using same size and I can load these without mechanical assistance.

30 metre range this morning, 10 shots under pleasant conditions. Zero Tech on 12 power, rifle on bipod.

Nice Mercs!

I'm in the middle of testing my SIG .177 too and I'm happy to say I've just found the best pellet (I think - more tests to go though) for my barrel.

It was the AA Heavies but now I've found better! It's now the H&N Baracuda Match .177 (10.65gr) with 4.50 headsize.

The 4.51's and 4.52's were no good but the 4.50's produced lovely groups at 50yds. I'll post target pictures when I confirm this - I'm just waiting for another tin of H&N's to arrive so I can test again on a less windy day....

I'm a happy chappie.... this topic inspired me to re-test my SIG and I'm glad I did! I think my 50yds groups will now end up about 30-35mm. We'll see....

Fingers crossed! Smile

Hi all, my .177 Sig is now set up like Ralphs with Zero Tech Vengeance 3-12x40SF scope found under the Christmas tree. I will review scope separately.

Strong variable breeze from right to left so shortened up range from 38 to 33 yards to try and get some shelter.

Last pellets of the day were H&N Power (copper plated) which surprisingly seemed to group better in the wind. I will do more trials with these.

cheers

Started with known pellet JSB Exact 8.44 grains 4.51mm for a 20 yard accuracy check no wind, rifle and scope working well.

H&N Baracuda Match 10.65 33 yards sighting in, wind gusts from right.

No surprise heavier pellet went low and left. Adjusted 5-10 clicks at a time moving around the bull then 2-3 clicks each way trying to get a feel for it. Reasonable turrets and look forward to some repeatable and usable distance numbers.

H&N Barracuda Power 10.65grains (copper coated) no adjustments made, 33 yards POA was bull, steady breeze from right.

I have tried the JSB Monster Exact Diablo 13.43 gr in one of my Sigs.

Average of a 10 shot string over the chronograph was 737.16fps giving 16.2 fpe

Got tight groups at 20 and 30m, the drop off at 40 and 50m compared to the 10.34 JSB's meant they weren't worth continuing with as a hunting pellet

Final target from me on pellets.
Have very few 5.50mm AA left saved for hunting.
Using the not as accurate 4.51mm sorted, just playing.
Took 3 shots to range and windage. Three attempts at bulls. Then stopped cause was happy with that and knew I'd pull a shot at some stage and spoil it. 😁
Depending on which way hare was facing 3 kills or two kills and a serious wound.
Hopefully tighten up with 4.50mm
