Does any one know if it is safe to fire .458 Lott ammo in a .450 Ackley chamber?
Thanks.

A mate of mine use to have a 450 Ackley that was made by rechambering BRNO 458 Win.

He necked up 375 H&Hs to 45 and fired those in the 450 Ackley so firing 458 Lotts in his rifle would have been just fine.

An excellent way to make slightly short 450 Ackleys!-Rob

I would not do it "A Lott" as you are starting off with 2.80" brass in a 2.85" chamber, and will wind up with 2.75" or so brass. Tends to clog up the new found freebore area of the chamber with powder residue, leads to high pressures if you fire full length brass.

What is wrong with using the correct length brass? Buy some Norma or Hornady or BeLL cylindrical H&H basic brass.

Yes it's safe. It's kind of like shooting 38 Specials in a 357 Mag chamber. Don't make a steady habit out of it (corrosion and wear in the neck/throat portion of the chamber). Remember, 458 Win Mag in the Lott, the Lott in the Watts, and the Watts in the Ackley. Think 38 S & W/38 Special/357 Mag/357 Max in a 357 Max gun. - Dan

Thanks to everyone that replied. I do not reload, so I have to buy loaded ammo. I have A-Square ammo for my Ackley, but I noticed that the Lott ammo was cheaper and it was available through Hornady.
Thanks again.

recoilpad,

The bigger the cartridge you shoot, the more you have to shoot it a) to get acclimated to the recoil, and, b) to become proficient.

It definitely makes economic sense to handload for the bigger rounds.

If you are planning not to reload for good then you can probably treat it just like a 458 Lott.
