[QUOTE="Long Time Long Ranger, post: 606475, member: 505"] The Lazzeroni and the 338-378 wby are big heavy hitters that put you into the big 338 category and the ones to look at if that is what you want. The 338-378 wby has been about as good as it gets with a big 338 since several started wildcatting it in the 70's. After 40 years it is still at the top in a hunting weight rifle. I have seven of them. If you want a heavy hitter it is an excellent choice. The edge mentioned on here is one of the many names given to the 338-300 RUM. It and the 338 RUM which is a factory cartridge and has the same performance are on the low end beating the 340 wby by about 125 fps. Those two are excellent choices for a guy wanting to get started cheaply with a donor magnum action and learn the ropes of long range before getting into the big 338's. I did quite a few 338-300 RUM's for guys from 1998-2001 because they were the biggest thing out there that could be done cheaply on a standard magnum action and got a little more performance than the 340 wby which was the best until then. In 2001 the 338 RUM came out with the same performance as the 338-300 RUM and fit better in the rem 700 action so was the better choice from then on. The 338-378 wby and similar size cartridges will outperform the RUM's by 225-300 fps depending on the rifle. It outperforms the 338 lapua by about 200 fps. The Lazzeroni is between these and the 338-378. The Excalibur case improved also gives top performance. The problem with going to a big 338 is cost. So that is the decision. How much performance do you want to pay for. [/QUOTE]
