6SLR out of Peterson or Starline?

[jrbet83]

Has anyone tried to make 6 SLR out of Peterson or Starline 243 brass? I'm not wanting to turn necks and am looking for a better option then Remington or Winchester brass.

Anyone have a few pieces that I could buy, to try myself?

Im still waiting for peterson brass to give it a go but I think you will need to turn necks if I go on what I hear with other calibers. Sounds like they have thick brass around the shoulder/neck

First have you tried using WW? I have, my 6SLR shoots great with it.

I switched from W-W to Lapua and my scores jumped dramatically.
I hope this helps.

Robert Whitney said he did NOT recommend using the Lapua brass. I have had to neck turn all of my new WW brass. My accuracy started going to hell when I switched to new brass and found out the necks were to thick and causing me pressure problems. After turning the necks it shot like a house of fire. New WW brass quality sucks!! I have seen a lot of bad flash holes in new brass. Some it it looks like a bathtub instead of a circle. My "New" brass was purchased years back.....

I stayed away from Lapua for years because Robert said to. When I chambered up my current barrel I had it throated for the 110 SMK to seat just in front of the donut area. When I turned the brass, I gave enough of a relief cut at the neck/shoulder junction that the brass had somewhere to go.
As of this date, I have had -0- issues with Lapua brass.
I hope this helps,

My life is to short to shoot WW brass in anything, I have used Lapua for a couple years and the rifles shot amazingly with it. I prepped 200 new pieces of Sako brass the last couple weeks and looking at the piece of sized/formed SLR brass I think I might have found a winner as long as the primers pockets holds up. Will shoot a ladder and a couple of loads in the next week or 3 and will know more but all I did was clean up the necks like I would do in any rifle and go. The lapua brass worked very very good but I had to cut away allot of brass especially on that "donut" area that forms after sizing the brass and I felt it left me to much sizing down after firing the brass

I worked with 50 pieces of Peterson. Neck turning is required unless you have enough throat.

So how did the Sako brass turn out? Petersons developed donuts for my friend in his client’s SLR.

I’ve been using lapua in my SLR as well. A little time upfront but after that
smooth sailing. I’m with capt. oblivious on this one life is too short to use

Very happy with the Sako brass, gave them a lite turn and loaded them. Load in virgin brass is .2gr less than in the lapua and the node is just about the same. Time will tell how they hold up but for now im happy. Friend of mine also started with sakos and he shoots them straight out the DIE.
The couple weights and measurements I took on the Sako brass also looks very good, its strange because as far as I know Norma makes the brass for sako and I had the same donuts when using Norma as I had with Lapua.

Far right is as they come out of a Whidden FL DIE before any turning

Hear! Hear! on recent Winchester quality (as Raptor says too!) Re Sako, I've seen it said several times now that it isn't made by Sako in Finland rather Federal Cartridge Co. in the US under contract, (likewise Sako ammunition). I don't know if that's true, but the two cases are very close whenever I get a chance to compare them (weights, water-capacity, neck thickness) and Sako brass also sees case-heads/primer-pockets expand quickly with hot loads, or even after any significant number of standard working pressure loadings.

 

[Capt. Oblivious]

As far as I know Federal and Norma makes brass for them in different calibers but things change so quickly they might even be making brass themselves now or some unknown guy might be making the brass, what I do know is this lot of Sako brass works very easily and even if it is Federal Federal is short changing themselves for not putting out all the brass they sell in the same quality as the Sako brass.



Perfectly round primer pocket (it’s not that hard Winchester), very consistent weight (I actually stopped after weighting and measure H2o capacity on 25 pieces) and nice round flash holes without burrs, had a dented neck here and there but they go through an expander anyway so it’s no problem. If they will hold up is the main question but the primer pockets are very hard if I can call it that, my K&M cutter suffered to cut them any deeper or wider but I know they won’t hold up as long as Lapua brass. If they give me 8 reloads per case ill be happy but like I say time will tell, the lot of Lapua brass I used the last season made this rifle a dream to shoot so the Sakos will have a bit to prove and If they cant match the Lapua brass Ill dump them and get another Blue box filled with brass. My next chamber will be a tight one and then ill use lapua again but with this chamber I suffered with carbon as a result (I believe) of having so much clearance between my chamber and necks after having to cut as much of the lapua necks as I did.


With that lot of Lapua 243 brass I had a 105gr HVLD going at 3300fps and there were still space to go, the pockets on those couple of pieces are obviously looser then the load I settled on but they still managed 10 more loads and they are still going. I doubt the Sakos will get close to that but it looks like a decent piece of brass to use

You may well be correct as contracts change and Norma has in recent years set out to become the number one contract supplier of quality cases in the West, and/or supplier to companies introducing new cartridges which aren't mainstream and don't have large production volumes.

The 243 Sako brass I have is some years old and I'm 90% convinced it's Federal. Super quality, but now barely usable after 7 or 8 firings at normal pressure firings due to primer pocket expansion. It originated in some budget shop-clearance Sako factory 90gn FMJ ammo in out of date packaging. A couple of hundred rounds of this ammo provided enough brass to comprehensively shoot the remaining life out of an ex-UK police force Parker-Hale M86 heavy-barrel sniper rifle.

I hope the company does use Norma now as most recent production from that company is very good. (I'm not convinced their case-heads are as hard as Lapua's though in all models, so that's still the best choice for very high pressure loadings. Can't comment on Peterson etc yet as not enough experience with it. I did notice really tight pockets on new Peterson 260 Rem large primer brass, so have hopes it'll last a long time too.)

Just a little update on the sako brass. Went to the range early yesterday to confirm my "fireform" load before my last match this coming weekend. Conditions were as good as it gets on a range, 3-4mph wind blowing steady, 81 degrees F.

Check zero and the labradar said the first 5 shots were exactly where I wanted then to be. 3085-3092fps.

With the previous lapua brass the node was around 3150fps but this speed is where it seems to shoot now.

Ranged the steel plate at 886y, spun the golden eagel up 17moa and gave him half a moa for wind. Shot 3 groups of 5 letting the barrel cool between groups (driving down to paint the plat), al 3 groups avg rite around 2.5" with les than 2" vertical exactly where they need to be. Speed stayd between 3090 and 3080 for 14 of the shots with one dropping to 3077fps.

For now im happy

The rifle is a savage action with a no turn neck chamber in a Krieger 7.5 twist barrel
Have a never fired Peterson 243 SRP brass that after resized with widden full length bushing die with .270 bushing and loaded with a 107 Sierra hpbt can be forced to chamber as a dummy round. If you just skim the brass I believe it will fit as desired. I'm comparing a loaded, never fired Peterson piece of brass loaded with a Sierra 107 bthp. to a loaded and multiple time fired piece of win
brass loaded with the 107 for comparison. They are practically identical visually but the win loads much easier, leading me to the conclusion the Peterson needs slight clean up of neck to function as well as win as relates to chambering. Dealing with donut is next step. Appears my 107's may be just ahead of same.
