Show your Tikka ten round groups

[RWT]

Found a half box of the the ADI 69’s. Bottom group of 10’shots. Then shot a 20 round group from a new box. Top group . At least they are consistent w1.7” and 1.8 respectively.

Queation is are these accurate enough to use for practice and the Shooter drill ?

Yes, they are accurate enough for practice.

Tikka T3 .308 Win
168 Eldm over N150
Shooting as quick as I can get back on target.
Almost annoying how well it shoots, considering how little I enjoy shooting it.. I’m sure with a brake or suppressor it would be a lot funner

Took the wife out for a practice session.

I shot just enough of the ADI 69SMK's last June to show promise and wanted to really see how they would shoot.

I did a suppressor comparison at the same time. I compared an OG to a OG 6.5. both for suppression and to see if the weight difference affected group size.

As a base line, I shot a 10 round group bare muzzle. I can't find the target but it shot the ADI 69 SMK's into about 1.3" and the 73 ELDM's into about 1.5"

This batch of 73's shoots terrible. The first batch i loaded shot about 1 moa. I used a different primer on batch 2 and it's terrible. (B-2)
I tried the Reaper with the 73's just to see and it seemed to tighten them up slightly, but a larger round count would be needed for certainty.

Anyway, as you can see, the OG and OG 6.5 shot about the same. I was intending to keep the OG 6.5 on the gun since it's lighter. I was surprised by the high pitch crack it makes on a 223 though. I much prefer the lower tone of the OG.
Interestingly, I don't notice a difference in tone between them on my 243.


Then I shot a 20 round zero w/OG and 69SMK's


Then I did a 20 shot break and build, no time, just as quick as I could make a decent shot.
it was 27 degrees and still, mirage was a challenge...or I still suck...

If I miss or in this case, I'm off the bull, I want to know what exactly caused it so i can learn from it. I had just proved a 20 shot zero so I know it's me. I believe it was body position more than mirage.

In this case the butt was too close to the ground to make a fist grip. I couldn't get my hand in a good position under the butt no matter what I tried but I went with it to see how I did.
Trying to force my hand position was putting pressure up on the butt and it shows by the low center of the group and vertical stringing.
if I raised the front about 1", it would have fixed my rear support issue.

Good shooting! So you prefer the OG over the OG-6.5 on a 223? I have an OG that I was thinking about dedicating to a gas setup, but this is the first time I've seen that comparison and favor the 30.

He’s not the only one. The OG65 is lower dB than the OG on everything. However, people seem to forget that one of the drivers of the OG testing was to produce the “hollowest” sound possible- not so for the OG65. It seems to be a trend that people that have had TBI’s, concussive damage, blast over pressures, etc., do prefer the OG to the OG65- and to most other cans. It may not matter to some people, but for some it is real.

Interesting, and good to know! I have had some of those issues and am admittedly sensitive to concussion so that sounds like a good fit. On most fixed gas systems does the OG run fine standard, or need an adjustable block?

on a 223 yes.
I've shot both the OG and OG 6.5 on 6.5 Creed, 6 Arc and 243
for whatever reason, case volume maybe, it only has the crack to it with 223(Tikka), no gas gun yet.
It might just be one of those things I can't un-hear after all the shooting I've done and been around with the OG/OG L and the subsequent lower tone that isn't as annoying as the higher tone cans.

Having had a TBI, this caught my attention. Is there anything you can point me to on the hollow sound being better? I’m not doubting it, but wondering if there is more to this than what people perceive. I’ve got 2 cans - TBAC Ultra 9 (Gen 1) and Magnus CB - that I purchased primarily for overall noise reduction (at the expense of length). Mitigating more hearing or brain damage is pretty high on my list and I’d welcome any rabbit hole of research to go down to see if there is any benefit of changing, or if I’m good. Thanks in advance

Nothing medically in depth. It is generally stated that high pitched sounds are worse than low pitch (or high freq/low freq).

What I was speaking to is the user preference trends. It’s not uncommon without anything being said about for some people to prefer the thumpier sounding cans to the cans that have a high pitched “crack” or “hiss”.
It is common in the S2H classes for people to state that they would rather shoot next to people with the deeper sounding (even if technically louder) cans after a couple of days, then the cans that are objectively quieter but have a sharp crack to them.
Go all the way back to the OPS Inc 12th model suppressor and the general love of those who have used it and been around it extensively. From what I understand, in the development of that can he didn’t have sound equipment as we do now, but did notice that a lower toned can sounded better to him.

Very interesting, thank you. Might be useful in the suppressor section someplace, as I just stumbled on this a minute ago.

If baffle design/spacing is similar for both cans, it may boil down to wall thickness (additional mass & stiffness) changing the resonant frequency of the chambers.

The OG and OG65 are different internally. They had different goals.

Thanks. I will dig around a bit and see if I can find anything. It makes sense though.

I'm told the OG/OG 6.5 are different internally. The OG was designed with a lower tone in mind, the 6.5 was not. beyond that, I can't elaborate.

Thank you.

I really appreciate the sound of the OG on my 6.5 Creedmoor, especially when there are other cans on the range at the same time.

I need to get my measurement rig together and record some shots for TEF analysis.
