Sako TRG / TRG-S M995 Thread **Sticky??**
- Thread starter JBM_DC
- Start date
The CTR mag is held together with two pop rivets. Removing these makes the mag fall apart.
Som measurments, a bit of modeling, a few test prints and done.

It's hard to tell from that pic. But the easiest way is by the safety lever. If it's thin and just a square tab on a flat metal piece that goes up into the trigger it's the original. If it's a wide wing that protrudes outside the trigger guard it's the second. You can also tell by the adjusting screws but that's a little more nuance.
It's probably a first as the second is made to be less likely to mess up with adjustments. You may be best off to call Beretta USA. I know of people who messed up the original trigger and said they had to send it out to be repaired.
I have owned and adjusted many of the original ones and never had a problem but it happens, hence the change.
From your description it's a gen1.
He hasn't shot this rifle much at all since he's had it. Previous owner reportedly shot less than three boxes through it. For those shooting factory barreled guns, do they seem to prefer the lighter bullets ? It shoots the 250's pretty good but it doesn't care for 300's.
So far he's used S&B 250gr, hornady precision hunter 285's I think, some flavor of berger elite hunter, can't recall what they were loaded with and prime 300gr.
Sounds like an early TRG. Pre-2013. The initial run had barrels with 1/12 twist for 250 grain bullets, and wouldn't stabilize 300's. Sako quickly switched to 1/10 twists as heavier bullets became popular. Then around late 2013 they did a redesign on the trigger so people wouldn't tamper with it too much. Pre-2013 had a thin metal tab for safety, the post 2013 had a larger winged tab. From the pic posted thats a pre-2013.

Sako TRG-22 Trouble
My Sako shoots fantastic however I've been having a little trouble as of late. The Trigger mechanism was binding up so I sent it off to Beretta in MD and they promptly replaced it. Very good service. Now something else odd is going on. It only happens when you rack the bolt hard / fast...The...

Quick question, did Sako make the M995 TRG-S 338 Lapua Magnum in both 1:12 and 1:10 twist? I'm buying one online, and don't see a twist rate in the photos. Serial Number starts with 8883XX
Thanks so much!
Jeff
Thanks so much!
Jeff
Appreciate your response, thanks so much!! For some reason Sako lists their discontinued M995 338 Lapua with a 1:10 twist rate that's why I was confused, appreciate your help!
Jeff
The Vision Chassis has some options for the TRG-22 and TRG-42, now stateside being sold through GCP Rifle Co in Florida!
The TRG-22 has the option for a full chassis replacement, and both the TRG-22 and TRG-42 have a replacement forend option.
The TRG-22 has the option for a full chassis replacement, and both the TRG-22 and TRG-42 have a replacement forend option.
Unfortunately it will not work. Only the short action TRG-22 will work with the full Vision Chassis, there isn't a long action option for the full swap.
Thanks,
Sam
You certain about that?
I remember mine as 1:10

Yes, I bought one this year for mine.
There are few tricks to figure out that is different than the docs, and then fit/works great.
Stick a tight fitting brush or patch down the barrel and see what push distance it takes to do a full revolution of the rod, aka let the rifling spin the brush
Or! A TRG-42 stock, but then you need to manufacture a trigger guard/mag release and get a TRG-42 mag. (See my previous postings)
I just looked up a bullet stabilization software and if I inputed everything correctly, it said a 1:12 twist would stabilize a 270 gr ELDX very well, maybe my inputs are wrong?

Not 100% certain as a lot of weird stuff has come of the Sako production line through the years and I've been wrong before
. But I would be hesitant to trust the Sako website or ad catalogs since they are usually ridled with typos. The TRG-S also came with a lot of different calibers and barrel lenghts that are missing from the linked page.The TRG-S manuals and the sample I've come across (including mine) have been 1:12. Also, I've seen a statement somewhere on a local forum that all Sako LapMag barrels were 1:12 before the TRG-update, but I'll try to find where I've seen this.
But, I'm eager to hear what your measurements tell about your twist rate. It would be nice if it is a ten.

Finally put all of the pieces together for my poor man's TRG... I'm going to put a coat of Krylon on the factory barrel and brake for now, and then have the whole thing Cerakoted when I rebarrel to 338 NM. I just slapped the SWFA 3-15 on there to get a feel for the rifle, but not sure what I'll do long term for an optic.
The backstory: I got this M995 in the early spring for a pretty good deal with Redding Match dies and a pile of Lapua brass. Next, I picked up a KRG W3 and swapped rear ends +cash with a member on here to make it match my other Bravos. The rail was custom ordered from Murphy Precision, and I sent it along with an MBM brake that would blend with the factory taper to Long Rifles Inc to have the receiver drilled and tapped and the muzzle threaded and brake timed.
FWIW, it was my first time doing business with LRI (I sent along a Tikka barreled action for some work at the same time as this one), and they have one more loyal customer. Communication was top notch, prices were excellent, and the workmanship is outstanding.

I will check tonight what my TRG-42 .338 Lapua is. I believe 1:10 but I will confirm.Not 100% certain as a lot of weird stuff has come of the Sako production line through the years and I've been wrong before

What are you asking?
The trg-s is a 42 action with the top milled off.
The 22 is 20 mm shorter.
The trg-s fits in a 42 stock (as per pics posted above), but needs a trigger guard/mag release which KRG provides with the trg-s W3 chassis.
Never measured mine, as I have only shot Lapua factory 250gr. loads.
What would I need to measure this?
You'd need 1) a Hornady OAL gauge with modified case 2) and a bullet comparator along with a micrometer. There are other ways to do it as well, but that's probably the easiest. Essentially pushing a bullet out of the mouth of a chambered case until it stops against the lands, and then with the bullet seated at that length measure from the base of the cartridge to the ogive.
I'm sure there are folks on here that can describe that process more accurately and with more technical precision, but that's my version.
Or one of these?

As I am just starting out trying to reload., I am thinking of getting the tools I need now upfront, instead of incremental upgrades.
Wondering how the above would be vs the Hornady solution?
Though being a newbie, I don't think they are the same end result?

2 questions,
First has anyone run 6br in their trg? Mine is currently 308 but has been collecting dust for a few years after I built a bighorn but I recently started to play with it and like the action and trigger much better than the bighorn so would like to convert it into my prs rig. If the br won’t work, what the smallest case people have had luck with?
Second, when I run the bolt Fast I’m getting about 10% failure on the trigger. Once the bolt cycles the trigger is hard and won’t fire. I have to lift and close the bolt again and it works. An my ideas?
