M3 30 cal/slugs?

[johnp]

Looking for a 30 cal slug recommendation.
Right now I am shooting 47.2 grain Nielsen's and I'm getting 98 ft lb. I was wondering what weight slugs do you recommend for my build? I'd like to get it up around 130 foot pounds but I don't have the tungsten Hammer weight which is going to be ordered today and I'm assuming I need heavier pellets. If you have any ideas to get me up to the that energy please help me. Thanks
here are my specs as of now see pic. The darker writing is my specs as of now also how heavy can I go with the Factory Hammer weight?

Not same gun but my FX Maverick can make 150 FPE with heavy slugs in the 70-85 grain sizes. I would think you need at least 60 grain slugs at higher pressure than you are at now. For reference my gun is at 200-210 bar and I am using a 26 gram tungsten hammer.
