I just came back from the range where one of the guys did let me fire a handful of his 338 Win Mag reloads "by the book" (Hodgdon loading data, within specs, no extra pressure, brass perfect...) with 300 gr. Sierra HPBT bullets that he uses for his Ruger, with my rifle.
Apart for my sore shoulder , my relatively cheap Weatherby Vanguard did average 2513 fps on his chrono....
Well he did fire his monster (poor my ears) 338-378 Accumark (same bullets, Hodgdon loading data as well) and that loads averaged 2827 fps....
I always wanted the 338-378 (fun factor) but the price of the rig and ammo (or brass if you reload) kept me away....
In his own opinion, basically the 300 and so fps of extra velocity is not worth the cost......he thinks that the 338-378 is just a tech showcase (he got the dough so price it's not a factor for him)
I computed my results in a ballistic calculator and the 338 reloads I fired in my rifle would still have carried ~1600 ft/lb of energy at 1000 yards!!!
At 2000 yards the energy left would be ~700 ft/lb and the bullet would be just barely subsonic.... that is long range wallop territory to me.....
He tolds me that his Sako 338 Lapua with the same Sierra 300 grainers average 2650-2680 fps..... only 200 fps or less of difference from my "little" 338 Win Mag...
So what is your opinion?? 200 or 300 fps more are worth the extra cost for a Lapua, a 338 RUM or a 338-378???
Disclaimer...
With lighter bullets the velocity difference with the 338-378 could creep almost in 400 fps trerritory....still
Overall I was impressed by my Vanguard performance.....before the ammo crisis I was able to find relatively cheap ammo for informal long range plinking even for $30 a box.....definitely not the case for the big boys...
