Sorry if I missed it. Did you go with the Hybrid lite contour on this build? I have a Hyperion K and want to make sure there is enough material at the muzzle for it.
Yes I did, it seems to have plenty to seat against.Sorry if I missed it. Did you go with the Hybrid lite contour on this build? I have a Hyperion K and want to make sure there is enough material at the muzzle for it.
Have you been using standard Tikka mags? If so, have you had any feeding issues with the 22 GT?
Yes, I’ve cycled probably close to 100 rounds through the standard M magazine without any issues at all. Seems to cycle just fine out of mdt aics mags too, 308 mags without binder plate.Have you been using standard Tikka mags? If so, have you had any feeding issues with the 22 GT?
19", 162ELDM, 3.131 coal, WLR, 52.2gr H4350. Peterson brass.How long is your barrel?
I've got about 120 rounds through my 18in 1:9 Tikka light hybrid 284 win. Consistently getting 1.25ish 10 round groups at all distances.
162 eldx 3.100oal, 51.5gn H4350, cci200, Peterson brass, 2675fps
During load development I saw the same, clickers at 52.5ish and hard bolt lift at 53.519", 162ELDM, 3.131 coal, WLR, 52.2gr H4350. Peterson brass.
I will note that I am getting light clickers on the first firing but I didn't FL size the virgin brass so not gonna get too concerned just yet on that front till I set up the die for a proper shoulder bump now and see how things run.
Even the brass from the starting loads of my ladders have a tiny bit of click (IE 49grs of H4350 for instance). The primers aren't flattened or cratered at all and I can't see any ejector marks, some brass has a faint extractor mark on them. I'll clean the chamber well and get these all properly FL sized and revaluate. Might as well load up some at .5gr less too just to compare.During load development I saw the same, clickers at 52.5ish and hard bolt lift at 53.5

Was it virgin brass or did you FL size it first?Data points FYI
51.5 - 2672
52.5 - 2713 (couple light clickers)
53.5 - 2776 (primers slightly flat, hard bolt lift on 2 of the 5 shots)
This is my first time working with a Tikka, I could have misdiagnosed the clickers, I cleaned the chamber and bore after the initial ladder and haven't touched it since. I'm at 140 rounds now and it's been a flawless performer.
