Lazzeroni

[bearkilr]

Are Lazzeroni calibers "copyrighted" and only to be had by buying a Lazzeroni rifle or is it possible to rebarrel an ultramag Remington or similar?

I really, really want a 6.53 Scramjet, but not in a La$$eroni.

I know Sako use to chamber them on special runs and custom orders, they even may still do on occasion? These are real screamers!, cheers Dale Z!

I see Shilen barrels chamber for the warbird so the may chamber for the scramjet but not sure, send them an e-mail.

I understand we all like different things, and that is ok, but why a Lazzeroni? I looked up some loads - 100gr bullet @ 3745fps out of a 27" tube.

You can get close to that with a .257 Wby and greatly exceed that with a .257 STW - the latter can hit 4000fps with a 26" barrel.

You can also get similar go out of a .25-.300 Winchester Magnum.

Plus that Lazzeroni ammo and brass is very expensive! The others are easy to find and/or make out of cheap brass.

Savage also had the .308 Patriot 5 or 6 years ago while Sako had the .300 Warbird.

Some good points and info,thanks. From my research, the Scramjet has about 20gr. more capacity than the Wby, and I don't like Weatherby's, a personal thing, overpriced for no reason.



I'll have to check out the STW.

257 STW is the only cartridge with a short barrel life than the Lazzeronis! LOL well almost.

I've owned a 243 middlestead that would argue that statement....

Obviously it wouldn't be a prairie dog rifle. I'm pretty sure a person could expect 800-1000 rounds with allowing proper bbl. cooling.

Why not 257 off of a 338 lapua case? Sure it would burn ot a barrel, but the brass is top notch, and it should beat a 257stw for speed. Or a 257RUM.. Take a look at pacific tool's list of reamers might be some good idea's there.

Maybe a 257/50BMG..........the true definition of overbore.

Jeez the flame coming out of the barrel should BBQ everything with in 10 yards!

Lazz brass is probably over $100.00 per 20 in Canada, if you could even find it. If your not going to get a Lazz, I would suggest a wildcat with either WSM or RUM brass.

Once the Rifle (expensive) and brass is purchased the cost to shoot would only be a little more expensive, due to more powder being burned. This is not to different from the AI's, magnums etc. They don't get a linear increase in velocity from the extra powder burning.
I like the fact that we have choices and can have something other than just a 30.06 or .308 or 270. Not really needed but then neither is a 120mph car.

He said Lazzeroni, that means he doesn't care about half of the exhausted gasses being vaporized steel . I tend to think a 257-300 win mag would offer the best performance/dollar ratio for the calibres suggested, it will be so close to the 257 STW the critters won't know the difference. Uses less powder and brass is plentiful.

He did mention 6.5 scramjet...if he wants to stay in the 6.5 mm range i would suggest 6.5 STW / 6.5 RUM...better bullet choices, parent brass is fairly easy to find if you dont' mind remington .

If you do go ahead with the laz let us know how it works out.

The Scramjet isn't a 6.5mm, that's just the way Lazzeroni words his calibers, by groove diameter, not bore size. It's a .257.

I'm definitely going to look into a RUM wildcat. I like the idea of being able to use a Rem 700 ultramag as a base rifle. I have no intention of buying a complete Lazzeroni rifle.
The more research I do, the more it seems most replies are accurate. I guess at the time the Lazzeroni's came out, they were the cat's meow, but since some newer factory calibers have been modded, they pretty much became overpriced and hard to obtain, kinda like Weatherby.....
I also read several articles which suggest Lazzeroni's velocities are very optimistic and generally only obtained with lubed bullets.

Did you know that you can run a 7mm Rem Mag case through a .257 Wby FL die and whammo, you have cheap .257 Wby brass? No need for special dies, no need to find someone with a special reamer (or to pay for one) and the performance really is quite good - 3650 fps with a 100gr bullet. Or that new 85gr TSX at close to 4000 fps.

Yes, I knew that. I still have a bag of 7mmRM brass for doing this when I had a 257. However, they are not an exact match to 257, the necks are quite a bit shorter. Whether or not it makes any difference is up for debate.

I've never seen any difference but ymmv.

If you've owned a .257 Wby then maybe something new like the STW or .257-300 Win is in order!

From Relaoder's Nest
.25-300 Winchester Mag + RL22 + 100gr = 3813fps
.257 STW + RL25 + 100gr = 3880fps

IMHO these cartridges are really over-bore. The RUM case would just make it worse.

I think the .25-06 and the AI version of that cartridge provide a pretty good balance for .257" bullets - although I don't think we are talking about balance here!
