Baldhunter your comparison of the 338-06 with a 200 gr. AB to a .300 WM with a 200 gr. AB is a faulty comparison.. For the comparison to be equal or even close, you should use the speeds of a .30 cal 150 gr. AB to compare to the 200 AB in .338.. It is no great trick to get 3400fps out of a 150 in a .300 WM.. Or you should use at least a 250 gr. 338 AB and compare that to a 200 gr, 30 cal.. Things that look good on paper are not always what they seem..
What is faulty with this?Maybe you didn't understand my statement.I wasn't comparing apples to oranges like you.I was stating what velocity I was getting with my rifles with a 200gr Accubond in my 30-06 @ 2650fps,300 Win Mag @ 2860fps and 338-06 @ 2849fps.I wasn't making comparisons of different bullet weights and the speeds of them,I was looking at one bullet type and weight,the 200gr Accubond,the difference was 30 cal and 338 cal.Using the same case but increasing the caliber size,I was able to gain about 175-200fps over the 30-06 by necking up to 338.My 300 win Mag load was was running 2860fps and my best 338-06 load was running 2849fps.That was only 11fps difference in speed.And when you have a 338cal bullet going the same speed as a 30cal bullet of the same kind,which on do you think will have the bigger whoomp when it hits?Is the 338-06 as good as a 300 Win Mag?Hell no it isn't.The 300 Win Mag is far superior.In this particular case the 338-06 was a step up from the 30-06 parent using the same bullet weight and brought it closer to the 300 Win Mag I was using.
