Sako TRG load development thread

[uracowman]

I'm going to start this because I cannot find good load data for the trg anywhere.

My gun: 26 inch TRG 22 in 308

dies: forster micrometer seating die, redding full length resizing die

componenets:
178g amax
federal champion primers
federal GMM brass
varget powder.

I'm starting the OAL at 2.890 +/- .0005 on both sides. Currently, there are 45, 45.5 and 46 grains dropped into each case.

I'll report back sunday with the results.

TRG-22 load near end of thread...

My buddy just picked up the rifle referenced in that thread.

It's a short read, but CMS gives a load that his '22 likes and it's the Hornady 178gr BTHP over 43.6grs of Varget in LC brass trimmed to 2.005" and using a Fed 210M, bullets seated out to 2.840"

You might just have to fiddle with a few boxes of different bullets and a few brands of powder. The TRGs shoot well with most components, so it's up to figure it out.

thanks for the link.

I'll keep that load in mind, but I'm going to fiddle around to see if I can hit a combo that works.

wow I totally forgot about that thread. Thanks for the refresher.

do you know what type of ballpark OAL people are running through the trg when they mention .001 off the lands?

Re: Sako TRG load development thread

For the bullets you are shooting, you shouldn't need to chase the lands. People shoot tiny ass groups with factory FGMM and don't have to chase the lands. IMO, you would be better off finding where your gun shoots in terms of powder charge then chasing the lands.

I believe my load on my TRG is at 2.83. Why that length? Who knows. I know with the 175s it will shoot 1 holers with little to no effort. The throats on the TRG are pretty long.

Right on.

I currently have all my rounds at a 2.890 OAL, but I may just work off that just to be different. I have 10 rounds currently at a 46 grain load, but after talking to someone here on the hide, I am going to pull those bullets and opt to work off a colder load. Most likely, I'm going to take out 43.5, 43.8, 44.1, 44.4, 44.7 and 45 grains to the range this weekend to see how each one performs.

My TRG 22 likes 43.6gr Varget with 175 SMK,s AMAX and BTHP and it's the shorter 20" version.

You can easily jam while still having a little room left in the magazine, so it's not like they have a Remington long leade.

I'm thinking you might start to see a slight ejector mark at 44.4gr. Maybe the extra 6" of barrel will help you keep pressure a tad lower than mine.

Let us know how it goes.

Re: Sako TRG load development thread

Prelim results from today

I went out to the range for .308 load development and the results were quite good. I found two nodes, one at 43.9 grains and 44.5 grains because the other loads could not group for sh!t. I'm talking about 1.5+ inch groups, especially with the 45 grain loads I sent down range. Next week, I'm going to take out 43.8, 43.9, 44.0, 44.4, 44.5 and 44.6 grains to see which one groups the best, then I'll just load those. I'm sort of reluctant to fire the rounds at the 44.5 grain node because I could REALLY start to feel significant recoil at 44.5+ grains.

The loads:

178g amax
43.6g varget
federal champion primers
GMM recycled brass
2.890 OAL +/- .0005

178g amax
43.9g varget
federal champion primers
GMM recycled brass
2.890 OAL +/- .0005

178g amax
44.2g varget
federal champion primers
GMM recycled brass
2.890 OAL +/- .0005

178g amax
44.5g varget
federal champion primers
GMM recycled brass
2.890 OAL +/- .0005

178g amax
45g varget
federal champion primers
GMM recycled brass
2.890 OAL +/- .0005

Here are the groups below. It was REALLY windy out today, and at times it was so windy that it was hard to keep the gun still even with sandbags in front of the bipod. I don't think that would of affected the groups that much at 100 yards, but in any case, I'm going to head back out there on a calm day and run an evaluation.

43.9g varget, 5 shot group

44.5g, 5 shot group, jerked one really bad

Re: Sako TRG load development thread

Sako TRG 22 22" barrel after about 45 rounds life.

Aiming mark is 1inch sticker

5 shot group at 300m ignoring wind off the bench, still getting used to the rifle.
Federal Power Shok once fired (from a Savage) brass,
FL resized
2-3 thou headspace
trimmed to 2.010 max
Fed 210M primer
reamed outside primer pocket and deburred inside flash hole
HBC BJD 155gr Australian F-Class STD projectile about 10 thou off the lands
45.0 gr ADI AR2208 powder
Sun was going down and so Chrony wasn't playing but about 2750ft/s around 30deg C high humidity.

This quick load up and ladder test was just to get me going.

I am sticking with this load and spending more time shooting well until I can find more accuracy from reloading. I haven't experimented with much else and I'm sure there's much more to be gained.
