Recently purchased a new .223.
Fired about 10 rounds gave it a carefull clean with homemade pull through using only oil and dry patches no solvent cleaner. Went out and zeroed with different grain ammo and was happy with results, used about another 20 ish rounds.
Went out yesterday to try some 40g ammo, also tried some which had previously been good. Starting at 50 yds was out by about 5 inches left and 5 inches low. Got it back with adjustment of about 20 clicks, but what happened there ?
I am hoping someone is going to say, just needs a good clean with solvent.
I might add zero is 50 yds and 100 and 150 are well good enough for fox kill zone.
Scope is a non parallax on 7 times mag.
Q1 Do you think a good clean is in order ?
Q2 Should I zero at 100 yds ?
Q3 Should I get a parallax adjustable scope, so I can get a good clear image at all ranges, fancying a Hawke Endurance ?
Cheers in advance, first centerfire and learning.
