So I want to build another custom and I am kicking around the idea of a 270 allen magnum 7mm allen magnum or just going big with a 338 or 375 allen. So if you have experienxe with theses calibers can you please give your two cents and maybe a list of pros and cons. I already have a 338 lapua and a 300 win mag and I do reload. I hunt elk and deer but am kinda liking the idea of a fast 270 for deer but if berger gets the new 7mm off the ground who knows. Well I hope someone can shed some light on this for me.
You definitely picks some top end stuff! I really liked every AM I've gotten behind but there is some lack of fodder for the smaller cals. The 270 is one of the favorite cals but as it stands there are almost no interesting bullets that will survive the launch of the 270 AM, hopefully soon we'll see a couple but a 150 ballistic tip just doesn't hold much for me, a .700 BC 170 bullet however is cool but not a reality yet.
The 7mm seems to suffer the same as the 270, light bullets fast just don't hold much interest but there may be some bullets coming just nothing shown yet.
The 338 starts getting me excited, there are some bullets that will take the launch and have ballistic qualities that are most interesting, bullet selection real makes it stand out IMO!
The 375 is, well a 375, how awesome is it to watch basket ball size rock vaporize through the scope!! Shooting it is like eating potato chips, you can't shoot just one, it's crack for horse power junkies!!! But it has limited bullet options without going to specialized lathe turned $$ bullets.
Purely my personal take, I don't own one I just shoot everyone I can get my grubby hands on but I will have a 375 AM gun)
