Had this for about a month now. Just got around to posting.
It's a HS precision.
So far I'm in love... if you have a custom bob lets see it.

nice scope

Great lookin group! That is indeed a gorgeous scope also! What load you runnin?

My first custom is a Czech Mauser chambered to 257 AI w/ a cheap Adams & Bennett F34 contour tube in a Remington 798 take-off laminate w/ M8 6x 42mm Euro #4 reticle. It's been around a fair bit, but last fall I introduced this dink to 90 gr GMXs:



Fortunately I hadn't been sitting round the 'fire when I built it or I'd not have known that cheap tube would shoot 75 gr VMs so poorly:



...or 110 NABs:



...or 100 gr Interlocks (200 yds):



My Yugo 48 was finished last fall but I haven't had a chance to wring it out.

Blueprint:

Yugo 48 Intermediate Mauser action
S&K Sculpted Bases/Rings (plated to match rifle)
Dakota 3- position "M70-style" safety
Custom knob
Timney Sportsman trigger; shoe plated to match rifle
#3 CM Shilen 1-in-10" twist tube trimmed to 21"
Boyd's Classic Nutmeg laminate (grip drilled for cap; barrel channel free-floated)
Mahovsky's Metalife Plating
Now wearing a silver VX-2 w/ LRD

GOOD THREAD; I bet it yields some Grade-A Rifle Porn.

That was the factory target. They were 85 grain nosler ballistic tips I believe. I can provide load data later.
Currently it's shooting consistent 1" groups w/ factory loads.
Right now I'm in the process of working up some 100 gr ttsx loads.

You got yourself a fine shooter and a looker.

Man a 117gr Hornady Interlokt boat tail and some 4350 will make these Roberts shine. powdr

I started out loading mine w/ IMR-4350 & 100s. That worked really well, but the stuff doesn't flow so nicely through a measure.

I've been working with Ramshot Hunter in both my standard Bob & Better Bob (as well as my 6-250, 280 AI, and 30-06) and getting FANTASTIC results speed- and accuracy-wise. If you can find some I highly recommend it.

It flows like water through a measure, too!

I look forward to seeing your results!

EFW, Those are some outstanding customs you have there. I especially dig how you were able to take some inexpensive parts and put together that second 257 that looks great and shoots better, on the cheap!

This link has a load for hunter powder

Very nice! I dabble in the Roberts round a bit. It's wearing a 6x42 matte now.

Be still my beating heart... we need details! That one is HOT!!

09 Argentine action, Leupold M8 6X

I was able to acheive .8 today with 80 gr ttsx and 48 gr of hunter.

Excellent! That'll knock em dead fo sho!

Don't know if you're inclined, but I'd bet you can go up a grain or 3 more before experiencing pressure issues.

Are you running magnum primers? I've gotten best accuracy results from them (and lowest extreme spreads in velocity) w/ Hunter in all 4 cartridges I've tested.

Sounds promising! Don't overlook the 90 gr Hornady GMX if you're into tipped monometals.

Thanks for reporting back!

Today I tried 47 48 49 and 50 with plain large rifle primers and no visible signs of pressure.
Take a look at barnes website.

I will be getting 500 free bullets from hornady for free so some 90s will be inbound.

257 Roberts Ackley Improved Rimmed Shilen select match barrel on Uberti 1885 action with home made scope mount/forestock/bipod tube.

The butcher said that mule deer almost never drag the nose on his floor, usually only elk do that.

That's awesome Clark! What load you use to take that cow?

That was 115 gr Nos Bal Tip at 3050 fps.
I would go faster, but the Norma brass is soft as butter.
