Never saw a rifle in one of those 2 calibers.
Can you give me some informations in relation to 22-250. Higher vecocity, bullet weights, twist rate, accuracy.

Know nothing of scramjet, Lazeroni is special order with own cartridges. 224 Weatherby is about duplicate of 22-250, with belted case. Discontinued yrs. ago.

The Lazz Scramjet is a 6.53mm (25 caliber) along the lines of the RUM only not quite as big. Nothing like the 22-250 at all. It will push an 85 grain bullet at 4000 fps.

Both are high end units (read expensive). I had a 224 Weatherby Varmintmaster several years ago and sold it in favor a 220 swift which I still have.
Back to the 224wby the only advantage to the 224wby is that it is exotic (smallest belted mag/case). Honestly the 22-250 will do everything the 224wby will do and more.
As far as the Lazz it to is a exotic too however giving you great top end performance but at a cost. The brass is very expensive around $45 for 20. I like the Lazz rounds as I have a Lazz 7.82 Patriot chambered in my long range XP 100 and love it.

If you are thinking of the 224 Weatherby - I have RCBS dies, boxes of factory loaded rounds and factory primed cases (never loaded) ready to reload, I would sell.

I see, th 22-250 is the way to go. Its hard enough to find ammo for it in Germany.
Tanks for the advices.
