Let me start by saying that I have nothing against the Rem 783 or people getting out and shooting no matter what rifle they have but, Ryan and Kthomas, and Go_Big_Tactical,
you guys hit the nail on the head. There are better options in that price range. I have owned a couple of 783's and by no means do I think they are junk, but the use of investment cast parts in critical parts of the gun and lack of support means there are better options.
Tikka T3 CTR 6.5 Creedmoor 24" Barrel - $1289.00
KRG Bravo Chassis - $595.00
TOTAL: $1884.00
Most Tikka factory barrels shoot extremely well and a upgrade is not likely required. But even if you wanted to a prefit from PVA would probably be about $650 after USD to CAD exchange and import costs. So you are still only looking at about $2500.
You could probably sell the CTR Mag/Stock/bottom metal for at least $100 making it even more competitive. Lets do a comparison of features.
Tikka:KRG Bravo is better than anything currently available for 783, plus basically all large aftermarket Chassis/ stock manufactures support the Tikka, Manners, McMillan, MPA, KRG, XLR etc.
Rem 783: Limited options - not likely to change anytime soon.
Bolt Lift -
Tikka: 75 degrees
Rem 783: 90 Degrees
Bolt Handel Attachment -
Tikka:Robust dovetail attachment - easily change to different bolt handles/knobs in 5 mins no gunsmith required.
Rem 783 - Less than desirable brazed on bolt handle. Oversize knob requires gunsmith, which a lot will refuse to do on the 783 because it doesn't fir their Rem 700 jig.
Case extraction:
Tikka - Robust Sako style extractor.
Rem 783 - Savage style sliding extractor. (Arguably less robust).
Bolt takedown:
Tikka - Tool less
Rem 783 - Tool less
Firing Pin Assembly:
Tikka - Robust piece machined from steel.
Rem 783 - Investment cast, weak spring right out of the box. **I have concerns about the longevity of the cast bolt plug/cocking piece on the Rem 783. See pic below, this was wear right out of the box with basically 20 cycles on the action. Maybe it will be a problem maybe not. The piece rotates every time the bolt is cycled. I don't like the idea of a pot metal type cast piece in a rifle that will see a very high round count it just doesn't give me a warm and fuzzy feeling. I have logged about 1500 rounds on my PRS rifles this season and at least double that in dry fire so lets say 4500 bolt cycles in one year, I am not sure Remington designed the 783 bolt plug/cocking piece to ever see that in it's life time. (just my opinion)**
Trigger:
Tikka - Bolted to action for easy swaps, extremely crisp, very nice machined piece. Timney aftermarket 2 stage option. $10 yo-dave option for lighter pull if desired.
Rem 783 - Bolted to action for easy swaps. Investment cast housing no aftermarket support.
Prefit Barrels:
Tikka - Available from Patriot Valley arms. Swaps are arguably easier due to recoil lug design (no lug to align.)
Rem 783 - Prefits available, need to have gunsmith notch action for savage style recoil lug to make swapping barrels easier.
Interchangeable bolt heads:
Tikka - No support
Rem 783 - Capable - but in my experience getting the bolt head from PT&G is not a problem but getting all of the extractor & Ejector parts and pieces from Remington is.
Action smoothness -
Tikka - Very smooth right out of the box.
Rem 783 - Just as smooth after worn in or sanded.
Scope Mounting:
Tikka - Action has provisions for pic rail recoil lug - arguably more robust.
Rem 783 - No recoil lug on rail.
Action Machining Tolerances:
Tikka - Take bolts and barrels from different guns and still headspace - Yes, I have done this.
Rem 783 - Yes based on Jerry's experience.
Resale -
Tikka: If you decide you don't like the sport or want to upgrade you will recover the majority of you money.
Rem 783: Not as desirable and easy to sell.
I have owned a couple of 783's and by no means do I think they are junk, a lot of what Jerry is saying about machining quality and features is correct, but in my opinion the use of investment cast parts in critical parts of the gun and lack of support means there are better options, even on a budget.
FYI - I don't currently shoot a Tikka as my main PRS rifle so I am by no means a fanboy.
