I highly doubt you’ll see much difference what gun are you shooting and bullets a 308 tends to be a pussy cat that eats everything

Went out to the range on Sunday. Got the rifle sighted in for 100, 200 300 yards with the 150 FMJ boat tails, shot acceptable groups at all three ranges. Cleaned the barrel and shot the flat base with the same powder charge and primer. The flat base bullets did rather well at 300 relative to the the boat tails. Using either bullet would would work for shooting the steel plate at 300 off hand once I get up to snuff. Now I need to start practicing..
thank you for the info and advice..

My only aversion to flat based bullets is that they are a little trickier to start into the case when seating. For hunting any supposed advantage in accuracy of a flat base is offset by superior downrange ballistics of boattails but it really comes down to what works in YOUR rifle. Not if you chamfer necks.. I prefer flat based bullets, I think they penetrate better... of course that can be an opinion instead of an observation..

Some .308's shoot 150 grain flat base bullets better than 150 boat-tails because they have a long throat e.g. Remington 700's, and the only way you can get anywhere close to the lands with 150's is with flat base bullets.

I prefer flat based bullets, I think they penetrate better... of course that can be an opinion instead of an observation.. Necks are chamfered. Boattails are easier. Boat tails are definitely easier. However, it depends on what flat base we are talking about. Some are far easier than others. I just loaded some 150gr Nosler partitions, but those are actually chamfered to allow for easier seating. Some flat based bullets are not like that at all and are a biotch.. Now, as for accuracy. This has been brought up a 100 times here. Generally flat based bullets are more precise at moderate ranges. Say out to 400 yards. But after that, the boat tails are generally better. They are more streamlined, so it only makes sense..
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

Boat tail vs flat base bullets are an enigma in the dozen or so 7x57's I have owned. The longer throated barrels don't care much for boat tails, but with only a couple exceptions they all liked Nosler Partitions even though there is a light chamfer at the base.

My std. bullets for the .270 Win and 6.5x55mm are flat-base Speer GS, 150 and 140 gr. respectively.
For decades, it was the Speer Hot-Cor and then Nosler Partitions swapped in for hunting. Both flat-base as well.
Only boat-tails are the Barnes TXS bullets, but they shoot very good as well.

Most every rifle I have tested flat base bullets shoot better at 100 meters. I suspect it would be different at 500 meters.
Example: my 300 savage shoots 150 grain Interlock flat base under 1 1/2 MOA, it shoots boat-tail 150 grain Interlocks around 4 1/2 MOA.
I have rifles that shoot boat tail bullets well. But flat base bullets almost always beat bt’s in accuracy in my testing.
I still test both.
I prefer classic.
