I didn’t shoot today, but I cleaned up my range. I also moved a piece of steel and looked at a few places to put some new steel.

I’m tracking.Yes. The speed difference is typical for long-barreled guns. Once you get past maybe 18" or so (I have no way to know the exact predicted length) all the powder is burned and the expanding gases are adding less speed to the bullet than bore friction is subtracting. Or, it gets slower.
I shot some of it over the chronograph with my 27" 513T just now. Fifteen shots went 1040-1100 average 1081.5'.
(ETA: And 10 shots from the 513T after sunset at 40 yards with peep sights, went into 1.8", which is about as good as I get in low light. Better than the short 457 did).
As for why the two guns shot different....there's things that'll make a combo shoot artifically bad, not many things that'll make one shoot artificially good, so I suspect some quirk with the 16" gun. I'll figure that out when its can baffles are clean.



Working on subsonic 38 Special in a 16” Marlin lever rifle. Using Bullseye and 125 gr plated projectiles, 4 grains of powder netted ~ 1000 fps. That was good enough for me. Came home and loaded 500 rounds. Should be fun, cheap, shooting.
Do it!The thought just crossed my mind about what an incredibly useful truck-gun that would actually be, especially if a selection of those subs and heavy .357 stuff was kept with it too. Talk about versatile...
Geez, that's a really nice looking rifle. Funny enough. I bought a rikka super lite. I like it but don't love it. I am getting back into bolt guns. So in looking to build a 18" shorty tikka. But right now I'm looking to take my tikka out of the krg bravo it's in and place it in a bag compositeMy new semi-custom Tikka T3X 6.5 CM w/ 20" barrel, wooden RokStok, SWFA 6x, AB Raptor 8 w/ 3" reflex. 10.0 pounds. 45.75" long.

This rifle also experienced an unexpected drop test. The magnum rifle shooters interrupted my string to ask me to please go cold. Flustered, but not wanting to offend anyone since I literally joined yesterday, I left it on the bag. And it promptly fell three feet onto concrete. Zero did not shift (but the brand new AB suppressor took the brunt of the fall).

I had a bit of mirage, despite the suppressor cover, by the time I got to this group. That, and I suck.

That group is unreal. Wow.Shot a 10 round group with 88 TMK's from the 223. First load combo tried with a new powder and primer.
