dont laugh just yet but i seen an article once............

a guy pulled apart a Ruger m77 (or howa) and stripped the bolt, then drilled a while bunch of holes in places to lose some weight.... end outcome was alot lighter- an i notice the Abolt i have, seems to be very heavy in the Bolt.
any gurus here , an whats the possibility of stripping the bolt an atempting to lose some weight with it??? or skeletonise it in places, bolt handle, shroud , but the bolt sleeve itself..woweee.

Thoughts?

its something id do lol
 
Might want to strip cocking piece, shroud, firing pin etc. from that bolt - then weigh that bolt body. Lock up is at the front (I think) so rest of it could probably be made of plastic, I think. But not certain how much actually available for weight reduction. I do not have an A Bolt here. Just weighed several Mauser 98 bolt bodies - some military, some "sporters" - so ranging from 255 to 275 grams - so 9 to 9.7 ounces - some with, some without extractors - might be able to steal 25 or 30 grams (an ounce)?? without compromising important stuff??
 
An A-Bort Composite Stalker weighs in at 7 pounds 2.08 ounces, according to the folks at Browning. Throw a light scope and rings on there, you're well over 8 pounds.
As my very good friend Charles has alluded to (guaranteed, even) above, there probably isn't enough weight to take out of the bolt to worry about, quite yet. A cubic inch of steel weighs about 4.57 ounces. Sounds like a lot, but really isn't. Think in terms of 1/4 inch cubes weighing about an ounce, or an ounce and a quarter.
You'd have to define how light you wanted to go. Most say it's a 6 pound rifle, scoped, which really is a sub 5 pound bare rifle.
Start by weighing the stock, and the barreled action, to see what you're working with. Fortunately, factory stocks tend to be heavy, so you may not need to scrape much off the action, IF you can find a lighter stock, preferably around 1.5 pounds, or less.
What is the target weight here?

Rman, that was a very thoughtful post so no criticism at all when I suggest there are 16 quarter inch cubes in a 1 inch cube. Each weighing 0.3 oz. At least I think that is correct.
 
So, if you drilled with 1/4" diameter drill. And took out a 1" total length of hole - so total of 1/4" diameter by 1" long - would be .049 cubic inches. From above, at 4.57 ounces per cubic inch, that one inch of drilling would amount to 0.2244 ounces - about 6.4 grams - less than a 1/4 of an ounce... Unless I screwed up the Length x Pie x "Radius" x "Radius"...

ha ha , good one! i am going to find this Article just to prove i am not mad, an it is just a thought, money it is but better than hunting with a tikka...

RE the stock weight, i believe its 26-28oz ..... 750 grams or so? that isnt heaps? * going off internet forum where it was asked an someone replied there abolt.

i thought about having the barrel thinned? or have those flute things in it? or going new barrel all together different profile an length proberly...

the magazine itself is quite heavy... im going to think about drilling holes in the side of that thing :D haha

thanks for the post rman, i think stock is 26 ounc? take to it internally with a dremel... :D
 
what stock are we specifically talking an can You guys get it/available?

what is the CAD for it?

il look them up online in Aus an see what pricing looks like an what the Weight is.
 
26 ounces is hard to beat, really. You'd be spending a lot to get anything much lighter than that. It means your barreled action is around 5.5 pounds or so.
Next step is for you to decide where the finish line is. What is the target weight of the rifle?

Rman good Question an with the magazine out.... rifle feels pretty good or better.......... i might modify the mag to just a top load per say with spring an no box.............(like remingtons)

then flute tube an it should be in the ball park as a comfy all dayer... no kimer... but no abolt.

200grams or 300grams seems reasonable? maybe up to close to half KG if bolt skeletonise thoughts??
 
What caliber is this abolt?

The 30/06 composite stalker is the lightest. 22” factory barrel.
I have a 280 Rem composite stalker handy, with heavy steel Browning mounts and a vx2 3/9 it weighs 7lbs 11 oz. The 22” barrels are too light to flute IMO. The 26” magnum barrels could be cut to 24.

That bolt is stopping a massive explosion from coming back in my face so I would leave it be. Drill some holes in the stock that will not cause it to splinter.

Maybe read that part again...

Just because someone took the time to write something down, and someone else published it without really thinking about it doesn't mean much.

Better way to look at this, is how much do your eyes weigh? In the event of a pierced primer that is the weight that you would be cutting, instantly, and permanently. Doesn't happen very often, but it would only take once if you had a bunch of holes drilled in your bolt sleeve and a cartridge worth of flame and hot gasses took the path of least resistance 2" from your eyes.

You are not going to make the gun noticeably lighter by drilling it full of holes. If you want a lighter rifle you need to rethink the entire arrangement.
