Alex, I had seen this video, previously, but I did watch it, again, tonight. They do provide a useful description and demonstration (e.g. eye, thumb [reticle], and target) of parallax that makes the whole concept easier to grasp. I found the discussion of the magnitude of possible error due to parallax (I had to study the chart [at 6:07] very… Read more

Hi, Alex! I see you already found my thread! (And I just now posted in yours and referred you to mine.)
Based on my discoveries since my last range trip, I have made some additional adjustments on my rifle.

First, I felt the eye relief wasn't optimal, so I removed and remounted my scope to bring it about 3/8″ closer to my eye. Now I get a good,… Read more

Alex, you might find it interesting to follow my own post as I have been trying to get consistent sub-MOA performance from my new Tikka T3 Lite SS in .308. You can read about my discoveries along my own journey here: https://tikkashooters.com/public_html/general-discussion/hunting-the-sub-in-'sub-moa'/msg3517/#msg3517

That said, I may have had an… Read more

Larken, it sounds as though you are describing what I've heard called the “artillery hold”. Perhaps that technique is worth a try on a future range trip.

I appreciate the encouragement. I guess I came off sounding kinda negative? I sure didn't mean to. I'm actually enjoying the learning process! I am incrementally exposing faults with the gun… Read more

Yes, Ericbc7/airfoil, I was pleasantly surprised to achieve the improved results with the addition of the muzzle brake.

It is clear, though, that I'm not quite “done” with learning/tweaking my rifle, yet. (or with tweaking the rifleman 😉 I was doing some dry practice in the Appleseed manner, and it became apparent to me that my “check weld” was… Read more

Eureka!!! I've found it! I would never have guessed that adding a muzzle brake would have improved accuracy. Reduce recoil, sure, but improve accuracy, too? It did both!

OK, so the first 3-shot group of the day was way off target, but a nice 0.5″ group. The second group was a 0.625″ group at the exact same POI shift. I dialed it back to zero and… Read more

OK, I finally got over the flu long enough to get out to the range and test the new recoil lug. To sum it up, I'd have to say that I can't tell any appreciable difference. I've got my Witt Machine clamp-on muzzle brake installed, now. I'll make another range trip to test that before making any further adjustments to try and improve my accuracy.

I… Read more

Update on this thread. I've identified a new suspect in my quest for consistent, sub-MOA precision: the aluminum recoil lug. I've got to say that, while I've read that this can make a significant difference, I have been slow to believe it could really make a difference. I mean, aluminum is pretty permanent metal, right? But I've ordered a steel… Read more

Thanks for the input, y'all. Yea, I've been next to folks with muzzle brakes on the public range, and it isn't particularly pleasant. And equally unfortunate is that the public range is, for now, my only convenient option for a place to shoot. That is why I've been wondering whether I could get the same reduction in muzzle jump by using an… Read more

mikgarus, I'm not sure if you were trying to condescend to me (OP) or to airfoil??? BTW, my rifle is a .308. If I understand what you are stating, you seem to be among those who find the back blast associated with muzzle brakes annoying. Is that right? Keep in mind that we were discussing how to reduce “muzzle jump”. If you can share some… Read more

A muzzle brake cuts the recoil down considerably on my .308…still bounces (benched, with bipod and bag), but if I hold right, it comes back to point of aim…almost.

I have anticipated a response like this. I haven't any experience with either, but I am wondering whether a muzzle brake or a mercury recoil reducer might produce better results.… Read more

Optics aside, if your bench technique is lacking, then all your data is suspect.

Sit your rifle on a bench with bags such that you don't need any muscle or input to maintain hold, even if you look away or only touch the rifle with your shoulder and trigger finger.  Not exactly true but close enough depending on caliber and rifle. (I wouldn't…

This is repeat posting of this, in case anybody is still watching this thread and not my other thread (Re: Learning the Vortex Viper PST FFP 4-16×50 rifle scope)

OK, I finally got to visit the range today with my new Weaver Tactical 3-15×50 scope. The first observation I can report is that the glass definitely provides “superior image resolution”… Read more

OK, I finally got to visit the range today with my new Weaver Tactical 3-15×50 scope. The first observation I can report is that the glass definitely provides “superior image resolution” as compared to the previous Vortex 4-16×50 scope. I easily obtained zero in about 2 shots from the 25 using the bore sighting method, so that's a positive, too.… Read more

Well, I thought I would put this thread to bed for good. I did send the scope back to Vortex for service. Long story short, while it cost me nothing (but time), it came back to me no better than it was before. After describing the issue in detail to their service personnel, their best recommendation was to try either their 2-10 or 6-24×50 models,… Read more

It will likely be a few more weeks till I get my scope back from Vortex and have an opportunity to provide another range report. But in the mean time, I ran across an article in American Hunter (NRA periodical November 2014) on the Weatherby Mark V Ultra Lightweight RC (i.e. Range Certified) in .270 Wby. Mag. In this product review, the author… Read more

David, thanks for posting your experiences with your Zeiss scope. You didn't mention at what range you shot your ram? BTW, I applaud your decision to limit shots on wild game beyond your proven ability to make a clean kill.

I opted for the Vortex 4-16×50, however, I don't really expect to do much hunting. I am having issues with focus and… Read more

I've got two threads that seem to be converging, now. Rather than update both threads, I'm going to try posting a link to my other thread here:
https://tikkashooters.com/public_html/general-discussion/hunting-the-sub-in-'sub-moa'/

Well, I went to the range today. I had removed the “nubbins” from the inside of the factory synthetic stock in hopes that those might have been introducing some unhealthy harmonics. I can now slide a dollar bill as far as midway up the chamber bulge in the barrel. But, alas, it seemed to have made no discernible difference.

My average 3-shot group… Read more

The Adjustable Objective is strictly for dialing out parallax error.  It's not suppose to be used for focus.  As Jacob Bynum says “Focus is a byproduct”

Using the name Jacob Bynum as my search parameters, I was able to discover that he is a shooting instructor. Sounds like a fella could learn a great deal in one of those classes! As far as how to u… Read more

I don't see much difference in parallax inside 600 yards

Robert, do you have this same scope? If so, are you saying that your experience is the same as mine? Are you able to bring the target into “sharp focus” using the side focus knob? When you shift your eye position slightly (either side-to-side or up-and-down), do you see the reticle move in… Read more

Personally I've never had any factory ammo shot consistent sub 1 moa groups. My .308 T3 shoots 1/2 moa groups with home loads but that took a while to get the load developed.
Might be worth loading your own

My expectations are somewhat skewed, I suppose. My first Tikka T3 was identical to this one except the caliber which was .270 Win. With that… Read more

Have you adjusted the “fast focus” or “eye-piece” focus?  That's the part near your eye that should bring your reticle into sharp focus. 

Yes, I employed the “fast focus” eye-piece to focus the reticle. I am extremely presbyopic (or far sighted), so I doubt that the average shooter who picks up my rifle would find the reticle in sharp focus for t… Read more

As the OP in this thread, I now have some updates. I got my rifle back from CDI Precision. They installed new bottom metal so that I can use the 5 and 10 round AI mags. And I got my new scope, a Vortex Viper PST FFP 4-16×50. (Previously had a Zeiss Conquest 3-9×40 with duplex reticle) Of the two potential accuracy issues discussed previously: the… Read more
