Unless your using a BSA with the ocular lense loose
HAH!
The ocular lens eh?
Until a couple weeks ago I never realized why there was any adjustment to the ocular lens focus on this scope (chinese made Millett TRS-1 4-16x50), because I could turn the side focus dial, and always get my target in focus. It did always bother me that at 100 yards, turning the side focus to 100 yards did not leave me with a focused target. I'd read how the printing on most side focus dials rarely lined up with where they actually had to be to give you sharp focus at indicated range, so I just wrote it off as a typical flaw in this design.
So I'd always kept my ocular lens in the middle of it's adjustment range (halfway screwed out). I've said for years I should get glasses, so a couple weeks ago, I decided to check something. I first looked at my target using typical settings. It was in focus. The side focus setting indicated something close to 150 yards I think (at 100). I then moved my head just a little side to side, and the crosshairs moved all over the place. Hmm... So I wasn't really parallax free. How could I have gone so long without checking this?
So how did I get the parallax to go away? I began by turning the side focus to indicate 100 yards, which did not put my target at 100 yards in focus. I then started playing with the ocular lens adjustment. I found that with the lens all the way screwed in tight (no not overtight), the target came into focus! Moved my head side to side and? MUCH BETTER. Very little parallax. Now did this improve my groups? I've been doing a ton of load development trying to find a load for the 34gr Dogtown using Ramshot TAC powder. I figure if I could get an accurate load, it would be much more affordable. Well I've seen hints of great accuracy, but it's been very inconsistent. If you read the threads concerning my testing, you'll see I've narrowed it down to a possibility of Kroil or CLP getting in the barrel, OR, something's loose on the scope.
And what do ya know I found tonight. I go to check for wiggle in the ocular lens of my scope, and sure enough. The tube wobbles.
What's worse is I'm pretty sure I could send it back (I think I'd be sending it to Bushnell now), and it would most likely come back unfixed. It's probably within tolerances for a scope in this price range. I can shoot MOA groups with it, just MOA 2" high left one time, and 2" left the next. I've been reading stories about people sending scopes back to Millett and never getting it back too now, so nice... I know some will say it serves me right for believing the hype. The box did have a big bald eagle head on it! Add it to my list of signs of our times, and how we're just selling our souls to the Chinese. Here was my contribution...
Anyone know how I might fix it? I guess if the ocular focus works with my vision while screwed in tight I can loc tite it there... ?
Thanks for the reference to the ocular lens jo. I'm glad I checked it now anyway...
