If I recall correctly that thread, somebody commented that German and other gunmakers upgraded their 6,5 x 52R barrel pressures sometime before World War I to the 25-35W standard. As a a matter of fact my 12x 12x 6,5x52R drilling built before 1923 has been firing Winchester made 25-35s for several decades with no trouble. My CIP Bullet table says that Pmax for 6,5 x 52R is 2450 bar, while Pmax for 25-35W is 3050 bar. Sellier & Bellot sells a 6,5 x 52R at 2200 bar, according to a Frankonia catalog from 2003. So we have both bullets in the market so far. If in doubt I would do some research on manufacture dates for a gun with this calibre and should consider proofing if possible.

[quote=montenegrin]"6.5x52R is 25-35 Winchester."
I once wrote this here but was vehemently opposed by a member of this board (who doesn't seem to be active anymore). It's true that under CIP standards 6.5x52R is loaded to lower presserus compared to the American version (which was of course the first on the market). I wrote to the CIP Direction in Belgium for an explanation when and why this happened but, predictably, received no answer.
With kind regards,

Jani,
6.5x52R is still 25-35 Win with another name. It is not uncommon for a cartridge to be loaded to different pressures in different countries.Examples of this are 8mm Mauser as loaded in US vs the Swedish and German loading, and 22 Hornet as loaded in US and Germany.Indeed,some cartridges were loaded differently for use in differently proofed guns.Examples of this are 9.3x72R and 8x60/8x60R.Some were loaded to different pressures for use in rifles vs use in pistols.Examples of this are 32-20 and 38-40 (WCF). Some were loaded to different pressures for use in the off season ( DWM had several such loads PRE WW2). Regardless of the different loads, the cartridges are the same. I'm sure this will create a "great gnashing of teeth", but there it is.
Mike
