Re: Idea! Official DTA SRS, HTI, Covert, Hunter Th
Guys, please help with windage adjustment when zeroing scope on DTA SRS!
I've zeroed it on DTA SRS with 308 barrel, and am very happy about the results (pretty must all the holes touching, cover one cent at 96m laser-ed distance). So I assume - based on this - that (a) my scope is properly zeroed on the rifle, (b) 308 barrel is co-axial with the scope, and (c) my shooting technique/quality is acceptable.
Then I switched to 338 barrel (I had very little ammo to use, and I hoped that once the scope is zeroed to the rifle - barrel change would just mean some elevation correction). And now all my shots are hitting about 1" left at 96m! (I've got some vertical spread too of course - but that one I expected.)
My fear is that this means - 338 barrel is not coaxial with the receiver and with the scope, which in turn would mean - no accuracy long-range.
These were my first few shots with 338 LM, and I have never shot anything heavier than 308 until now.
I need to figure out three things:
<ul style="list-style-type: disc">[*]How likely is it to be an operator error (flinching or such and thus bringing shots to the left)? [*]If it turns out that indeed a different barrel in DTA SRS requires <span style="text-decoration: underline">lateral</span> scope adjustment - is it normal? Is it OK?[*]If it proves that indeed <span style="font-weight: bold">windage</span> (lateral) adjustment is necessary when switching barrels - does it mean this rifle won't be accurate with 338 because the barrel is not co-axial with the scope?[/list]
I don't need to tell you how new I am to long-range shooting in general, and to 338 in particular.
Please educate me!
Thank you!
