if you want a 3kg rifle the about the best you can hope for is a #3 at about 20" long

about offhand shooting so what is he built like

But is it a HB rifle? How would it handle long strings of shots? Remember I plink 10 at a time, x10 so 100 shots in one session. Don't worry this rifle definitely caught my eye... it would save a hell of a lot of work and $$. Have you had personal experience with it?

Still not 100℅ sure of the end purpose? Short medium range cheap plinking offhand? Pistol caliber lever? I dn

Laugh all you want buddy but I don't think so - give or take a few hundred grams. Remember it won't have optics so there's a few hundred right there. Under 4kg is achievable. The 223 mini action has a HB, AND it's 20", weighing in at 2.99kg. I never said I wanted a bench barrel - just not a sporter.
in2anity wrote:Off the back of discussions we've had in other thread I would like to propose a compact .30 cal, heavy-barrel target rifle that is still light enough to plink with offhand for extended periods at the range. It needs to weigh around 3kg, take most 308win projectiles, and have a tight enough twist to stabilise long heavy projectiles (perhaps up to 220gr?). It's really important that it can handle cast lead - this is what I'll predominantly be shooting; gas-checked 308 165gn rnfps. A 10 shot magazine is also a must.
So here goes (thanks Gwion for originally suggesting this idea):
1. Pick up a Howa mini-action HB in .223 (preferably with a target/varmint stock)
2. Have it rebarreled and re-chambered for 300blk
3. Get it dovetailed for a front sight at the same time
4. Throw a target aperture receiver on the rear mount
So here are some questions for you knowledgeable folk regarding this proposition:
a) The muzzle diameter for the Howa mini-action HB is .725"; would rebarreling up to .30 cal mean it's heat-dispersion capabilities would be dramatically reduced?
b) Would it be safe to presume that such a rifle be still as deadly accurate (sub moa 5-10 shot groups)? Would the thinner barrel dramatically change the harmonics and thus accuracy?
c) Would there be enough meat in the barrel for the front dovetail after the rebarrel?
d) What twist rate would be appropriate? 1:7?
e) Would I be just better off buying something off-the-shelf in 300blk (like the Ruger Ranch)? Any other 300blk suggestions to fill these requirements?
f) Are there already 308wins that realistically tick all of these boxes; i.e. lightweight, short heavy barrel, tight twist, 10shot magazine, very accurate?
Any advice would be greatly appreciated.

didn't see this bit in the op just the bit about the for sight and it didn't click so this will be a fun little project .

300blk only needs a 16" barrel for powder burn etc. Any more is a bit wasteful, hence why they all come in ~16" lengths.

I suggest you check out the magazine and it's demensions because I know the 223 with 50 and 55gn projectials is a snug fit, and you may have seating depth drams with 30 cal.
But it would be a good thing if you could get it up and running

If you want to stabilise heavy bullets at low velocities then you probably do want a 300BLK barrel (not that 168gn is heavy in 30-cal.).
The alternative is to order a tight-twist .308 barrel at whatever length you want. Use a slower powder and I'm sure the bullet will still be accelerating at the muzzle of even a 30" tube, it just won't be doing so as efficiently as it does in the first 16" or so.
You can probably pick up a Ranch rifle for what you'd pay just to buy a custom barrel, plus the cost of fitting it to whatever action you already have for it?
And if you don't like it you can resell it for almost what it cost you.

It'll be going transonic by about 400m as well. A 150m zero puts it 90mm high at 80m and 200mm low by 200m. It's also down to the "magical" 800ft/lbs by 200m. At the muzzle the 300BLK has the same velocity that the .308 still has at 500m with the same bullet.
in2anity wrote:Very interesting Blade - thanks for this information mate I really appreciate it Nothing like a few facts to ram-home the truth. I'd punch paper at 300m with it, then maybe stretch it out to 500m at Hornsby down the track. Hunting - never past 150m with irons. I might varmint with it though if I experimented with a scope...
Ok how about this then - instead of 300blk, how about use the 7.62x39 action instead of .223? Although then it's technically a wildcat... would it be dangerous running 0.311 projectiles through a .308 barrel (i.e in case I put. factory 7.62x39 ammo through the.308 barrel)?
