Depends on which tradition it might be and what the bolt or hammer design might be? But if you shoot t7-3f and a 300 grain bullet in an older falling hammer style gun you could expect excessive blow-bac... It is simple math vs older designed guns.... Remember these guns were being built before T7 even made it on the market.

The question is do you understand why T7-3f builds a higher pressure quicker than 2f in a given volume space?

I can get the same thing in my White with a heavy bullet and T7-3f or even the Remington with a Remington Conversion - so are those guns bad also?

One further point if you go back and read Cayugad's post you would find that the retaining spring is a concern with the BD. Even when I bought my CVA Firebold, CVA recommended purchasing a 5 pack of retaining springs for the nipple. it can be a problem in older guns...
