150 or 180 grain?

[seamus30]

Hi, I have a BLR in .308. Last year I shot 150 gr Winchester with it and got good groups, I also tried 168 gr with mixed results. I thought I had bought 150 gr at the store but when I got to the range I realized I had 180 gr. I figured what the heck and I shot a few. I got really good groups with them, they shot about 4" higher than the 150's. So my question is, Whats the difference going to be, other than the weight difference, when hunting?

Thanks.

Don't matter too much, use the ammo you are confident in and shoots well.

Nothing here that will know the difference of 30 grains.

Just some trajectory changes you may notice with range practice.

If you're getting longer legs with the 180's, use them.
Nothing wrong with a bigger bullet.
I use 150's in my 308win Ruger.

For moose the weight and construction of the bullet matter more than on deer.

I love the 308 with 150's for deer.

A few friends of mine had better luck with 150's on deer than 180's. With the loads they were using they got more bang flops on deer with 150 grainers.

I do not think it would make a big difference,other than if you are shooting at a moving target.If that is required,its nice to get used to one speed of bullet.

Best bet is to find out what your gun likes best.... I like 180's because I'm a fan of heavier bullets and it just so happens that my rifle does aswell
