I have been trying to figure out the weight of two barrels that I'm trying to figure out how to bestgo about reducing their weights (T3 lite 308 Win & T3x lite 223 Rem). Initially I was thinking about swapping out the barrels to two Proof CF in 20" variety... but those aren't cheap, and wondering if there isn't a better option that would rival the weight savings for fewer pennies out of my pocket. Problem is, I can't find what these things weigh in the first place, now what weight I would be looking at subtracting from those initial weights for things like cutting the original down and/or fluting them after a cut down. Doing research and though I haven't found my complete answers yet, I thought I would post what I have came up with from various other sites, to have all in one place, for anyone else who might find it helpful.
If you have anything to add, comment, etc., I'd appreciate any and all information. Thanks!
- T3x 308 & 223 = 6.4 lbs factory weight, complete rifle (add 0.2 lbs for factory open sights)
- T3 = ??? factory weight of complete rifle varied 6 - 6.5 lbs from various source and couldn't find it on Tikka website any longer to verify.
- T3x 308 & 223 = 22.4" factory barrel
- T3 308 & 223 = 22.4" factory barrel
- T3 receiver, bolt, and trigger = 30 oz
- T3 : Adding plastic mag box and bottom metal to above = 33 oz (aka 3 oz more for these to be added on)
- T3 BA = 4.4 lbs (aka 70.4 oz)
- T3 barrel (unknown caliber or length) as deducted mathematically from above info:
- Never found anyone who weighed just a barrel, and only found one person who weighed a BA and they didn't say what caliber it was, or the length, but using the two figures above: 70.4 oz - 30 oz = 40.4 oz (aka 2.525 lbs)
- From context clues I believe this was a 22.4" 308 but they didn't specify that and I can't verify it, but it's the best I currently have to go off of unfortunately. Do with it what you will. They did specify it was a T3.

- T3x action (I'm assuming this means bolt and receiver, no trigger) = 28 oz
- T3x Unknown Munitions recessing = -4 oz (aka shaves action down to 24 oz)
- T3x 308: cut to 16.5" (probably technically 16.9") and threaded = -6.5 oz
- They noted they sent it off to be cut/threaded and could not verify themselves exact lengths.
- T3x 308: cut to 18" (probably technically 18.4") = -4.6 oz
- T3x 223: cut to 19" (probably technically 19.4") = -5.2 oz
- Question: So at first I thought this made sense, 223 would have a thicker wall so more weight reduction per inch... but the barrel lengths are the same on the 308 & 223, and Tikka is claiming the 308 & 223 weigh the same amount as a complete rifle... so is this data point incorrect, or is Tikka incorrect... or is there a explanation where these could both be correct?
- Apparently there are calculators for this if you have calipers and a loose barrel to take your measurements, such as this one: https://pac-nor.com/barrel-weight-calculator/
- Assuming by looking at the diagram on this page, I'm assuming most barrels are straight for the entire section that I plan on lopping off.
- If that assumption is correct and using the numbers from around the internet:
- T3x lite 30 cal = about 1.1 oz per 1" cut
- Given aftermarket barrels are interchangeable I would assume this applied for the T3 as well, but can't verify that.
- T3x lite 30 cal = about 1.1 oz per 1" cut
- If that assumption is correct and using the numbers from around the internet:
- Assuming by looking at the diagram on this page, I'm assuming most barrels are straight for the entire section that I plan on lopping off.
- Fluting... I didn't add any data points as there seem to be to many variables. How deep, strait, spiral. Let me know what you think one would typically expect from a flute job.
- 20" Proof CF 308 barrel = 2 lb 7 oz (aka 39 oz)
- 20" Proof CF 223 barrel = 2 lb 10 oz (aka 42 oz)
