Yes the Martini actions are sensitive to how they are held
Can you show us a target?

Something is loose.

That was my first thought. Nope. Tried two scopes. Checked bases. Checked stock bolt. Checked fore-end tightness. Tried another barrel, too, with yet another scope. Thanks for offering a suggestion.

Have several, what do you need?

Tiratore, thanks for the dm,I think you should post that information in the thread to give everyone the bigger picture.
When trying to assist information is the key to getting good responses.
Ignition can cause vertical, ie weak firing pin spring.
But before replacing the spring, I would stop using the graphite in the necks and lightly crimp the bullet in place. Many found that crimping the bullet improved consistency.
What are the readings from your Garmin?
Did the groups change when the barrel was replaced?
Btw that’s a nice looking Martini.

Is there too much head space?

Overall length? Carbon ring?

Ignition - good suggestion. I guess I'll try to disassemble and have a look at firing pin movement. Primers look OK, but I've had problems with a sticky firing pin on a 44 1/2. Caused vertical. Never disassembled this martini. Hope the hinge pin does the trick.
Also - both barrels produced similar groups.
Uff da.

October 8 group sizes - m.o.a., 100 yd, 5-shots each. In order fired. First 2 shots were sighters.

Hornets are very hard to get consistent velocity from. I have found 12.6 grains of Lil'Gun, Fed Small Pistol Primer and 40 grain Vmax or Blitzking, no crimp, will shoot well under an inch in over 30 22 Hornets we have tried the load in. The small pistol primer is recommended in the Sierra load manual and produce much more even ignition and tighter SDs, some replicate this with a light crimp on the bullet. We have never found a Hornet that would not shoot this load, If that load does not give tight SDs and groups in the .75 or better range, then there is something wrong with the rifle itself.
It has been producing these kinds of groups for 30 years. The target squares are 1/2" on a side, rather than the standard 1".

I would be interested in what you found and the results of load development.
When I get a barrel blank and some time I will build a 17 Squirrel most likely on a Rem 581, I'm hoping that I may be able to make it a repeater, otherwise I may use a Martini.

Nice 3-shot group -
I agree. Rifle or technique (sic.) problem, most likely.
Poorest groups associated with using bipod on a hard surface.
Other single-shots were sensitive to how they were supported and held.
Contact between fore-end and front face of the receiver was examined - some improvement with a trial fore-end with a gap between it and the receiver.
Is the 1.810" the overall length or base-to-ogive?
