Hello AGN,
I just picked up my first air gun, Sig Sauer ASP20. I haven't fired it yet. Anything tricks, tips, break-in I should know?
This thing is solid, makes my Ruger 10/22 feel like a toy.
Congratulations on your purchase and welcome aboard! There's a few guys here that own a ASP20. Me included. Look forward to your thoughts.
You didn't mention what caliber you chose. I have the .22cal and strongly believe the Sigs powerplant is more suited and efficient in .22cal. One pellet that shoots accurately is the Air Arms doomed 16 gr. This pellet fits easier into the bore than most of the other accurate pellet choices for this rifle. You will find that the ASP20 has a tight bore. The Sig Crux lead pellet at 14.66gr is the pellet Sig used for the velocity rating and is also very accurate. The rifle shoots best with pellets in the 15-16 gr range. One exception is the Sig Wraith alloy pellet which is very accurate but do fit tight in the bore. Both Travis at Airgun Depot and Tom Gaylord in their reviews found this pellet very accurate in the Sig. The pellet is listed at 12.35 gr but none of them come near that weight in the three tins I've purchased. They actually weigh 13.3 gr and have more of a semi pointed - rather than doomed - nose. My rifle shoots them at 880 fps and they are accurate ! My stock fasteners have all been treated with blue Loctite and don't come loose. The rear trigger guard screw is a wood screw so don't over tighten it !
