I used to do range reports, chronograph test, various test like suppressed vs unsuppressed and so on, on the RFC forum but them being the dickheads they are "dickheads=P___py, So__a and the clique gang, to many numbnuts to mention" I have stopped posting things like this over there. Now that that's out of the way let's start.
I haven't shot the Tikka 17 much so this time I really wanted to get a good feel for it accuracy and dB level. Yesterday, I started out with a Lantec Dragon muzzle brake because I had success with it on my 22's. It was way too loud and I had to wear earmuffs. Since this being a jacketed round I also decided to swap out pistons in my AAC Ti-Rant 45M and try it. I already had data from the Silencerco Sparrow and thread protector. I use a free app for my android phone called Decibel X. I put it under the trigger guard and record the MAX sound and just reset and repeat. I took 15 readings with the Sparrow, AAC Ti-Rant, Lantec brake and thread protector. Ammo used for all was CCI 17 GR TNT. Recordings from the AAC and Lantec were taken yesterday, the others were two weeks ago. The T-Rant really surprised me being "that" much lower than the Sparrow.
Results
AAC Ti-Rant 45M "full config" AVG 86.85 dB
Silencerco Sparrow AVG 93.4 dB
Thread Protector AVG 100.1 dB
Lantec Dragon Muzzle Brake AVG 103.7 dB
Next I want to show some photos of split necks I had. I only found 10 out of 50 but they were all out of the same box. This didn't seem to affect accuracy.
I had a lot of FT Eject this time, more than I remember having last time. I'm pretty sure I have it fixed now though. With one of my 22 Lr's I got it fixed on the first try but not this time. I made a bend too far forward and it caused my rounds to not come up high enough to feed. I had to correct that and make other bends. I'm going to cut the chase and tell you the way you see my ejector in the photos is how it ended up and it works great. I do have a little more resistance closing the bolt than before but it's not bad, just noticeable. I do want to point out and have included photos that the medical pliers makes it easy to access the ejector.
Now the accuracy part. I only shot 15 rounds with the Lantec to get the dB recordings so no targets with that. Can't find the targets with the Sparrow and Thread Protector. All targets shown were shot yesterday, roughly 350 rounds total. As you can see the 20 GR bullets didn't do so well this time. All the 17 GR shot great "to me". Yes, I did get lucky with 5 shots in the 1/8" group. But.....I'll take it. I can only post ten photos, that's the reason for another entry.
