300 RUM Bullet weight?

I have a new M 700 Police 300 rum, I was planning on shooting 180 gr. Through it, but after reading some of these post, I'm wandering if I need to go heavier? I've got other rifles to hunt with, it will mainly be a long range toy. If I did hunt 180 gr is more than enough hunting central Texas. I got a mark 4 20x sitting. On top. So shooting at a grand which weight will I have the best luck with?

The most important thing is to find a bullet your gun likes. A heavier bullet works better in the wind and has a longer range with effect. The 210 Berger would bea good one to try but you may need to try several to see what workd best in this rifle.

It'll depend on your individual rifle.

I have several freinds who shoot 1000yds plus with 300 Rums and 300wm's who swear there's no point whatsoever to going heavier than 180.

I also know guys that believe heavier is better because of the higher BC bullets.

I'd say buy a few boxes of different weight bullets (all same brass stamp) and just see what shoots best with the factory loads and then try to match that if you are going to reload.

180gr at 3,400 FPS is going to more than enough energy to kill anything in North America out to 1000yds if you put it through the bread box.

My personal experience is that very few rifles will perform with either the lightest or heaviest bullets, nor with the fastest or slowest loads available.

All of my own rifles have always shot best with a good high bc bullett in the mid range of the weight for the caliber at just under max FPS.

Sometimes you get lucky and get one that shoots everything great. I actually have a mini 14 in 6.8spc (customized) that shoots sub MOA with anything I run through it.

More often than not though there's just one particular bullet, one particular powder charge and primer that gives you maximum precision.

That's why long range fanatics spend so much time tweaking and tuning.

When developing a load it's not at all uncommon to just load 5-10 of each of a dozen different loads, bullets etc at a time and spend a day at the range just seeing which of them hits the sweetest spot.

When you find that perfect point, make sure you have enough similar components and enough powder of the same lot number and load as many as you can. Then you are set until you run out and have to try again.

Sometimes you get a significant variance between lot numbers of the same powder so having enough powder to just keep running is important.

When I was loading a lot I'd just buy several pounds of a given lot every time and then chronograph a few loads to see what variation we had vs the last lot.

Can't really sum it up any better than that, I am finally wising up and buying powder by the 5/8lb keg rather than 1lb. Lot to lot consistency seems to be a joke these day with most powders I use. Not gonna mention company names, but it starts with H and ends with N, lol.
