Well I've been having a play with chairgun and printed out a table and last night was the first wind free night in a while so off I went for a plink...using the table from chairgun I could hit bottle caps out to 65 yards with some decent consistency 65 yards was max as I started to run out of elevation turret.. Scope is a hawke sidewinder 6-24x56 1/2 mil dot I use the mil dots for when hunting but for this stuff I dial the turret...now I have shimmed the scope rail on my ttr and I've got enough elevation adjustment for 100 yards...so after I zero the gun in again (had to remove the scope to shim) at my local indoor range 25 yards and wait for a calm day what sort of grouping do you think is possible at 100 yards with pellets straight from the tin and shooting from bi pod taking me out the picture as I'll always let the gun down as I'm no super shot by any means but can shoot to a reasonable standard..
