Calling all .22 Syn/M-Rod EXPERTS!!!!

[Luzmartinezjr]

Here is the deal. Bought a new .22 synrod on black friday. I have shot about 500-600 pellets thru it. At 16-18 yds this thing is crazy accurate. I can shoot pencils and pens with ease. I love this gun!!  I am using a 4-16x40 center point. Yesterday i stretched it out to 70-80yds. No wind, nice calm day. I was hitting to the left about 4-5 inches consistantly with the "big 3" (18.1,21.1.14.3) pellets. So i adjusted my scope accordingly and wow!!!   I was hitting a 2inch target with ease. I was feeling great!!!! 
   Today on the other hand i was again shooting "using the big 3" at my 16-18 yard targets and i was hitting 3 mil dots to the right??  What the heck?
   Is there a slice (like in golf) to my pellet trajectory???  Has anyone ever heard of this??  Please help!!!

May very well be getting a slight HELIX flight path .... Try slowing it down / speeding it up a tad and see if things change ?

Know rifles new, but cleaning up crown, making sure breech is polished, rifling lead and transfer hole is burr free can help a LOT !!

Where is the crown? Breech? Transfer hole?  Pics would b great!!!  Sorry im a newb with all the lingo here.

I also bought a .22 synrod on black Friday. I personally think it shoots a tad too fast, like mine, but I don't know. I'm not going to tune my rifle without a chrony.

When I shoot 14.3gr pellets, I can see it in shoot in a spiral. I can't even put it on paper at 50 yards.

Yep could be a lot of things, a few more things to try are;

1- Make certain the scope rings are tight enough, but be careful not to over tighten.

2- When you are not using the rifle - try resting the rifle horizontal (see picture), like in a gun rest or similar.

3- I like to use a #113 90 duro O-ring in the air stripper (if you want, PM me and I can drop one in the mail to you at no charge, I keep extras). Some think the O-ring in the air stripper can take a "set", even if only temporary - and cause barrel alignment issues.

4- Another thing to try is to; back the shroud away from the breech 1/2 turn.

5- Try installing (after applying silicone) a #18 O-ring (3/4"I.D.x1/16"C.S.x7/8"O.D.) over the shroud and between the shroud and barrel band.

It's usually a matter of process and elimination, while trying the easiest first.

Scope rings r tight. Gun is always stored horizontal in my padded gun case. I dont know where that air stripper is??? I can get a #18 oring, but y the silicone?

Sounds like your reticle is canted, which means it is not exactly level in the rings.
