Yah have R22 on hand. By hot are you talking sticky bolt, primer signs, or ejector marks? And you’re .002 off lands?
Be nice if Ruger would put one out in the Gen II . Still looking for one with threaded bbl. Thinking 18"-20" for my needs.
I’m also planning on a suppressor and cutting my Swede back to 20ish. I’m interested to see if others have data on that combo but I’ll post here if/when I get things built up.Don’t Swedes like slow powders and long barrels? I’d think with the ballistics out of an 18”-20” barrel you’d be Creedmoorish or slower…..
Grabbed my book to refresh my memory.Yah have R22 on hand. By hot are you talking sticky bolt, primer signs, or ejector marks? And you’re .002 off lands?
Have a 20" prc, you'll be at 2800 plus no problem. That's what I'm thinking also for the Swede, light work and a good project.I’m also planning on a suppressor and cutting my Swede back to 20ish.

In my case I also picked up a 6.5prc barrel,with the plan to happily hunt with the PRC if I can shoot suppressed around 2800 (19-20”), while the Swede does target work at lower fps.
The VV website and Shooter reference had some helpful data points. With an 18” barrel down from the average 24” barrel or so used for many of the Swede test data, you would lose 150fps (if my reading and understanding on rokslide is correct). Given 2750 seems pretty achievable and below pressure on a longer barrel, 2600 should be pretty easy I agree. Keep us posted on what you come up with! I’m going to move to 44.0 grains IMR 4350 from 41 which should get me there as well and be a safe round. I will use slightly less for the 127 LRX and 143 eldx.I’m going to cut my Tikka down to 18” and thread it soon. I’m hopeful to stay at 2600+ FPS with 140 grain bullets, but anything above 2500 will work just fine for my needs. @WI-Carcosa your data makes me think I should be able to achieve that pretty easy
Great points, I appreciate the feedback. I agree on short length. No to the comparator but I need to check length a bit more. I will likely do the Form sharpie trick with a few various rounds.120g ttsx

Those are seated quite deep if your 6.5x55 barrel is the Tikka factory barrel. My factory barrel had a very long throat. The coal for a 127 LRX was @ 3.17" to reach the lands. Have you checked any of those with a Hornady L&L Comparator or something similar?
I can’t even get to the lands on some high BC bullets in my tikka, I run out of neck first. Those LRXs touch lands at 3.2 on mine120g ttsx

Shot a 10 round group of this pretty quickly to see how it would perform. Grouped very well with 2680avg fps, 60 es, 27std dev. This bullet shoots great in my 19” T3 6.5 Swede, I’m pumped. I am hoping the n555 shoots well and I can get a bit more velocity out of it. I am really hoping to hit 2750 with a 19” barrel.This one is from Hendershots and I had them work up a load for the 6.5x55 Swede in a Tikka T3 19” barrel with Banish Backcountry suppressor. They do a nice job, but with the Swede and lack of modern book values, most loads are pretty anemic.

135 DRT terminal shock
Lapua brass
N560- They did not share grains of power used, but I weighed components and came out with 48grains minus primer which I estimate at 2.5-4 grains. Guesstimating around 45g or so of powder.
2694.6 fps average, ES 52.9, Stdev 15.3
The load shot fine but my shooting today was terrible. VV SKAN loading table below.
I will be working up a 135g round with my uncle with 555 hoping to be north of 2800 with a bit better ES and stdev.
update on this for those trying to get more speed from a shorter barrel. I had Hendershots add .5g of n560 for an updated load shooting 135drt out of a 19” T3.Shot a 10 round group of this pretty quickly to see how it would perform.

Just ordered my own Tikka in 6.5se and got it cut down to 20 and drilled for open sights, odd question, do you have full pics of your tikka? Im buying a Wildcat stock this week for it.My all time favourite cartridge (and my most accurate / consistent rifle). I cut mine down to 19” (6 1/2 lb scoped/loaded), running 2675fps with 140gr AB’s with reloader 22.
I want to see a pic please when you're done. I'd love a short barreled Tikka with open sights.Just ordered my own Tikka in 6.5se and got it cut down to 20 and drilled for open sights, odd question, do you have full pics of your tikka? Im buying a Wildcat stock this week for it.
Stupid question here, but I see people mentioning the long throats on the tikka rifles, do most people when loading for hunting not go to cartridge base to ojive? Would that not solve the problem of how deep or shallow the throat is cut?Given the case capacity advantage of the 6.5x55 over the 6.5CM and .260, and the fact that tikkas have such long throats that I can get even more capacity than SAAMI says, I’ve had no problem hitting the velocity numbers you’re talking about. Out of a 22” barrel I’m getting 2700 with no pressure signs and plenty of room to go up using 140 grain bullets, 2600 with 156 grain bullets in a hot load, and right under 3000 with the 127 LRX before pressure signs showed up.
