Planning a New Build - Feedback and Advice Welcome

[TheNatural]

I'm in Canada and our lovely government recently banned the semi auto I used to consider my well rounded multipurpose gun so I'm building a "new" rifle to sort-of replace it. I'm planning something accurate, reliable, light enough to carry around, with good ergonomics, and capable of long strings of fire. I'm thinking ranges of 50-800 yards. Not a long range rig, but it will see some mid range target shooting. It could also see some close range hunting shots in dense woods.

I'm going to use the action and trigger from a Savage 110 Tactical (short action 308W), because I already have one broken in that I like and I know it's reliable. I'm going to use an optic I already have as well, an Athlon Ares BTR 2.5-15 which is relatively lightweight for the style of optic, although not the lightest. I want to keep it under 10lbs (including scope) but my current build list is going to put it a little over.. I could use some tips on cutting a little bit of weight. Also please chime in if you have an actual measured weight for something I've more or less guessed at.

Specs:
Short action receiver, bolt, and trigger from 110 Tactical - 32oz (based loosely on numbers I've found floating around this site)
EGW 20moa rail - 2.5oz (according to EGW website)
Athlon Ares BTR 2.5-15x50 - 27oz (as per Athlon website)
Burris Signature XTR Rings - 7oz (weighed myself)
18" CarbonSix barrel, 308Win - 39 oz (using CarbonSix barrel weight estimating tool)
Muzzle Brake - 2oz (weighed myself)
MDT LSS XL Gen 2 Chassis - 29oz (MDT lists as 1.6-2lbs depending on inlet, took the middle number)
MDT Skeleton Lite Buttstock - 26oz (quoted from MDT's Q&A on their website)
Grip (either Ergo or MDT) - 5oz?
MDT polymer magazine - 4oz (weighed myself)

That puts the total at 173.5oz... 13.5oz over the 10lb goal weight.

I thought about using a KRG Bravo instead of the MDT which would save roughly 12oz, but no left hand savage inlet available.
I could use the MDT LSS (not XL) which is listed as 1.4-1.6lbs and would save roughly 5oz, but I don't like the really short forend. I'd like to get a bipod a little closer to the muzzle and give myself more to grab on to when shooting offhand.
Leaving it in the Accustock could be an option, but I've modified it a bit and made a custom molded grip, added some QD sling cups, etc, and it weighs 3lbs 5.8oz with the bottom metal. I like that the chassis systems offer more adaptability for basically the same weight. With a chassis I could quickly attach an arca rail and some Mlok weights for a PRS match, add a "NV Hood" to give me full barrel coverage so I can use a J grip for 3gun without burning my thumb (without all these newly banned semi's I don't know what 3gun is going to look like), etc. I don't compete in anything enough to justify specialized rifles for every discipline, so having something adaptable is kind of nice.

Other places to save weight? I read somewhere on this forum that the big BA bolt handle weighs 5.9oz and I could replace it with something titanium/aluminum/carbon fiber to save a few oz? It's not worth the weight savings to put a smaller hunting style bolt handle on it to me. Any rings that are lighter but still solid? Perhaps I should invest in a lighter optic - anything significantly lighter that still offers FFP, good tracking, zero stop, etc?

Let me spin you in a different direction if I may. Years ago I worked on
what we called the poor mans assault rifle. Basically it was the 760
Remington game master pump converted to use a BAR magazine. Back
then the only AR available to the public was made by Colt. Now that
being said, and if the day came I had to give up my auto loaders, Id
move to a platform such a Troys pump actions. Or even find what legal
means you have to remove your gas tube, and convert to a side cocker.

I guess I would ask, why do you want to keep it under 10lb?

Looks like an interesting project.

The Troy PAR is an interesting idea. I'm curious about how accurate they are. I imagine a pump would be less than ideal for shooting in a lot of positions other than offhand, like prone. The straight pull model might be a bit more functional. We also have mag limits that would make them a little less fun... 5 rounds for magazines designed for semi auto rifles. We've been able to use 10 round mags that are designed for AR pistols (LAR, etc) due to some poorly worded laws, but they've also banned those pistols so I imagine they'll be coming for the mags too. No limits on mag capacity if it's designed for manually operated actions (AICS mags, for example)

They banned the upper and lower receivers of basically anything remotely resembling an AR15 or any of the other popular semi's, so I can't get around it by using one of the conversions for straight pull conversions or bolt action uppers I've seen online.

Just based on my experience carrying things. The custom Stag10 I can't use anymore was 9lbs unloaded (but with optic) and I liked carrying that around the woods, but I hate carrying my 12lb target oriented bolt action around. I figured sub 10lbs would be a good balance of light enough to carry but heavy enough to help with recoil and allow some flexibility in components to hit the other non-weight goals.

I kinda figured it was due to hunting.

Are you limited to cartridge? A good compromise hunting and long range target cartridge is the 6.5 (CM, 6.5x55, etc). A 6mm might even work depending on what you hunt. Then you could go lighter and be within your recoil limits.

I'm not totally married to the 308, but I do like the idea of 308 for a general purpose rifle. It's also sufficient for moose and elk at close range which is good for me.

The 6.5 Creedmoor is great and I have some brass and dies already, but I wouldn't try to use it on a moose.
