View Full Version : Savage 10PC/Sightron FFP - Also, why Match ammo matters

09-29-2013, 1:42 PM
Howdy folks,

I've owned a Savage 10PC in .308 for about 4 months now, maybe 450 rounds fired, not a whole lot. This is my first non-.22 rifle, so it was a definite step up.

I started with a Nikon M-308 BDC scope, then got a Sightron SII Big Sky from SWFA's Sample List, and just this week went big with the new Sightron SIII 6-24x50 FFPMOA, sitting in Leupold PRW Medium rings and Warne Maxima steel bases. (The Nikon now sits on a R700 SPS, and the SII is on my 10/22.)
A PRI Quiet Control brake on the factory threaded bbl, Harris BRM-s bipod, Crosstac rear bag, and hokey Uncle Mike's ammo carrier stuffed with a rag for a cheekrest round it out.

Like a genius, I forgot to take mags with me, so I single-loaded through the mag well.

For the first few sessions I bought cheapo ammo to get some practice, and it was the only way to get brass for reloading. It was CBC 147 FMJ, and shot maybe 2.5" at 100 yds. Today, with my new scope, I shot four different factory loads, now that Cabela's has a much better stock.

Sighting in at 100yds with Norma USA TAC-308 150 gr FMJ, 7 shots

Total rounds fired: 27; first 100 yd group is shown, worst was 4"

Next up was American Eagle 168gr OTM, 2 5-shot groups

About the same, around 2", 10 shots fired

Silver State Armory 175 gr SSA HPBT

Again, around 2", so I think we can see a pattern developing, WRT my skill level. (The shot in the top right is for a different target, I'm not THAT bad.)
Total fired: 10 rounds; both groups ~2"

However, saving the best for last: FGMM 175 SMK, 3 5-shot groups on 3 targets

These groups are representative of my shooting today; the Norma, SSA, and AE all shot about the same for me, ~2" at 100 yds. The FGMM almost made me look good. I was absolutely giddy after that first group, only to be ever-so-slightly let down with the next two.

So yes, better ammo (for your rifle!) = better groups.

I've fired a couple sub-MOA handloads (168 SMK over 37.9gr of IMR3031), so I've identified a couple options for now.

Most savage 308's are 1/10 twist and do really well with the heavier 175's. So when you get into reloading, you might want to stick with the 175's... That's what I run through my savage.

175 smk
44.8 g Varget (kind of stout load, but no pressure signs in *MY* rifle)
coal 2.810
Black Hills brass (winchester)
whatever primers I can find- usually cci.

When you reload and find the powder charge the rifle likes, it'll tighten up more. You're off to a good start.

What stock is that? does it have an aluminum bedding block?

And I thought my scope was big.... that thing looks GINORMOUS!!!!! LOL!

Savage 10 Precision Carbine
20" bbl, 1:10" twist
Accutrigger and factory Accustock in ACU Digital. I guess the Accustocks no longer have the little wedge that tightens down against the recoil lug, but it does have an aluminum bedding block, although it's not as beefy as what I've seen advertised on aftermarket stocks.

Scope is Sightron SIII 6-24x50 LRFFPMOA. Included 3" sunshade makes it seem bigger, probably. I doubt I'll keep that on for long with the shooting I do: covered benches at 100 yds.

My scope has a 3" shade too- it isnt a small scope... but for some reason that thing just looks really big!!! I'd leave the shade on anyway. It helps reduce the amount of dust that makes it to the obj lens.

I havent heard much about the new accustocks wedge or no wedge. If you're "handy"... you might benefit from a skim bedding action bedding.

Look at the very last group you posted... 2 touching.... 2 touching a little farther left, and a high flyer... This makes me wonder if your rifle would benefit from a skim bedding. Might be too soon to tell for sure though. Also could have been a shift in wind speed...

The other groups with 175 smk look pretty round... so it looks like a good velocity for the rifle, and doesnt really raise concerns about bedding issues.

Too early to tell for sure I think. I wouldnt worry about it yet.

Very nice, I've noticed similar differences between PMC bronze and Hornady Amax match ammo with my R700.

Where are you located? Just curious.

First, a correction: I do own a Puma M92 in .454 Casull, so I guess this isn't my first big-boy rifle, but definitely different applications!

Back on topic, how close should I try to get the scope to the rifle? The closest point right now is the objective cap, which sits 3/32" away. I have a Talley 20 MOA rail, but the scope sits much to high, maybe another 1/8" higher than with the Warne bases.

I'm looking into the skim bedding, and I'm not sure if it will work, as the Accustock seems designed to "flex" slightly, from left to right, as the action is torqued. Maybe I just need to mess with the torque settings.

Same area code as you, actually. It was the target that gave it away, wasn't it?

You can try bedding in that stock, but it will still flex. You're better off getting a stock with either an aluminum block, or a high quality synthetic you can epoxy bed.

You want the scope as close as you can get it to the barrel without is touching.

Nice shooting, hand loads will close those groups right up.

I have the same rifle as well, nice shots.

Try starting at 43.2 gr Varget with 175gr SMK, and work up. Keep us posted.
