Borderlands 3 - firing range

I’m one trophy away from platinum and it’s the damn firing range. I went through 60+ rounds with the boss to get the dictator gun to help but I’m still nowhere close.

Is anyone available to help? PSN mysteekmeg

Still need it? Just got it done myself so shouldn’t be too bad. PSN lukman4068. I’ll be around for a few minutes now and then again later this evening - about 4ish hours from now.
