Working on load development for my Mossberg MVP (1-9") and wondering if it would be better to try 40-50gr bullets, or 60-69gr?

I would start with the 69 smk.
Those 69 smk bullets are the standard for punching paper. They are what many people use for testing to see if a rifle is still good or gone. They are very jump tolerant and work great loaded to magazine length for service rifles. Another that seem to be well liked are the 50 flat base Sierras. I have not shot those but I have with 69 and 77s.Thanks for the responses. I have some 40gr BT and V-Max, so will give them a try. Will pick up some 69gr and try them as well. I plan on using it for gophers and also punching paper.
I found 40 gr bullets in a 1-8 twist to be the most accurate.Thanks for the responses. I have some 40gr BT and V-Max, so will give them a try. Will pick up some 69gr and try them as well. I plan on using it for gophers and also punching paper.
Gas up those 53s and get to testingFound some Hornady 53gr match and 60gr SP in my stash. More options.
From experience, you really do need to try a range of weights, and give each a fair shake. You won't know until you do.
At 1:9, I'm not sure I'd go heavier than ~70 grain, but it's still worth a box to try.
I've noticed some reviews for Hornady's 75gr BTHP match bullet... they said it does great in 1:9 twist. If that works in your barrel, you probably got a lot of leeway to try lighter bullets too. I recall 68's working nicely in a 1:9 too.

Have any Tac? That or h4895 would be a good start. Test both head to head if you got them.What powder would you suggest?
