I have only put a few rounds down range through the TRG A1. I was really disappointed with the trigger over the earlier TRG’s I have owned, it’s the same basic action with a new bolt handle just screws into the bolt body. The trigger had to be redesigned because there was an issue with the sear is adjusted to light by the end user causing it not to reset correctly when set light and and permanent damage would be caused. My last TRG was re-barreled in 6.5x47 by
@Ronin and I must admit I did like that rifle but the AX action just tops it.
I can understand you wanting something unique but I can honestly say that the the Accuracy International AT action feels far superior and the tiggers can be adjusted to a decent weight. This is the same action used throughout the short action rifles so the AT, AX308 and the newer AT-X.
The AT-X is designed with competition in mind with the chassis mimicking the chassis’s developed by the niche US companies developing PRS race guns. A factory rifle does always seem to hold value far better than a custom build based on a remmington 700 footprint.
I’ve had most but still own an AX308 with a custom 6.5X47 barrel. It just feels so more solid than the Sako’s in all guises. I have also got your old TAc A1 .223 barrelled action in a Sako TRG stock with the older TRG trigger. It’s a nice foxing rifle and cheap practice calibre as I can reload for 40p a round. It gets expensive plinking any of the larger calibres when even the cheapest bullet is 40p before you add a primer and powder let alone brass prices.
If you really want to keep value in any investment buy secondhand in the first place.
The TRG action is so similar to the Tikka T3 that in reality the Tac A1 would be a worthwhile buy and there would be no loss in accuracy over either the more expensive rifles of Sako or Accurate international. At the end of the day it’s the nut behind the butt that makes the difference.
A Keeper turned up to a U.K. PRS comp with a factory Tikka Varmint in .243 and schooled the entire lineup of competitors with custom rifles in go faster calibres.
I know prices have gone up but there is a secondhand Tikka Tac A1 for sale secondhand that would be perfectly adequate.
If you really want something unique the Fix is brilliant but probably too lightweight and the reason I ended up with seeking a heavier rifle for target work. Still own it and won’t ever sell
I know that having a young family and shift work certainly get in the way of attending comps let alone informal gong ringing now days to have so much invested in my kit sometimes does feel a waste. I do hanker after a crotch rocket but after the most recent work accident the wife is putting her foot down, well I certainly can’t

(excuse for glory shot of most recent metal work installed)
I even used my AX for a Chinese water deer last year to get some use out of it. Plus it’s so confidence inspiring it’s unreal.
So if
@One on top of two is posting glory shots I’ll have to join in…
Sorry for long reply. As you know I’ve got time on my hands…
