Load data compare to powder manufacturer
Hi, I recently joined to find data for 8x68s. Not many are available from powder or bullet manufacturer.
However, for the few I had there is a huge difference that I find hard to explain.
ex. From vihta published data. N160 and accubond 200 gr. Max load listed at 70.r gr.
Xxl reload give 64.3 gr as max load … and a lower MV of course.
Any insight ?
Cheers

Hi - this topic is the most commenly discussed and we get many emails with similar enquiries. However, we are happy to explain again:
When comparing load data, make sure you compare apples with apples, i.e. load data based on similar inputs
Our inputs are always stated on each load page, most importantly: COL, case capacity and safety buffer
In this particular case, you compare our data with a 3.374" to 3.425" at VH. We have a safety buffer of 10% while VH assumes 0
You can use our personalized load calculator and adjust our values to those og VH and get to a max load of 67.7 g vs. 70.4 of VH - a difference of 5%
Unfortunatly, VH only specifies that they use a RWS case but do not state the case capcity. if it is larger than what we assume, the gap would be reduced further.
Hope this helps to clarify!
