Norma Tipstrike 170gr load. Danger from Norma?
Hi Community
I am working up new loads for the Norma Tipstrike 170gr together with Norma 202 powder and I am totally confused.
When searching the XXL reloading site, I find a recipe with a Max load of of 40.1gr, Min 33,6.
This (max) load should result in 87% of max pressure.
Now, moving over to Norma homepage, I find the recommended max to be 44.0gr and Min 41.2gr...
How can there be such a massive difference between Max and Min between these two sources?
Further, I have checked in Gordons Reloading, which calculates the Max pressure with the XXL Reloading Max (40.1) to be around 96% of Max pressure iso the 87% . Of course, the Norma load (44.0) gives a MASSIVE (and dangerous) overpressure.....
Looking at Barnes TTSX 168gr indicates the same phenomena; Barnes figures differ MASSIVELY from XXL Reloading and their Max load gives and overpressure indication in Gordons....
I know that Gordons is not an official source, but being fairly new to handloading I am now at loss.
Anyone who could explain and assist?
Many thanks
