I just completed my first build. For about $3000 Aussie so around $2000 US
I paid $950 for a Tikka on clearance
$990 for a carbon fibre stock Bolly, made by Precision Defence Industries. Australian made.p
$900 for an IBI Carbon Fibre. barrel
And I have to pay the gunsmith when I collect in a few days, he will be fair . He fitted and chambered the barrel to .280ai.
Uhh, 150 Norma .280ai cases and some Redding dies cost nearly $500, I can't count projectiles but I grabbed a heap of those in 7mm as I run a 7mm-08 too.
So I built a lightweight rifle for about $3000. Alternatives like a Christensen arms Ridgeline would be $4500.
A Proof research barrel would be near on $1500
A McMilan stock could be $1500
A Custom action would start at $1500
That easily takes me over 5k k in Australia.
Building on a Remington or a Tikka. Can be viable pending what you want. I'm settled on That in my price point. I can test the IBI barrel, the Bolly Stock my gunsmith and my skills.
I also bought a Sterk ultralight Bolt shroud $130, I will swap an MTN tactical ultralight bolt handle from another tikka. MTN a NewZealand brand . This is 3D printed from Titanium.
I could be into nearly $4000 when I finish but that's cheaper than any off the shelf custom I've found. It's maybe my one and only build. Sourcing the parts certainly helped getting a quick turn around from the gunsmith and I know him so that helped.
