I have never tried this so I am asking will a .308 handle a 200gr.? Treestand hunting Saskatchewan. What is the gain over a 180gr. or is it just a wild hair idea? All shots under 150 yards. Just looking for a little more smack down with a gun I already own. Buckfever

200 grain .308 winchester

It's not a wild hair idea at all.

The .308 Winchester can accomodate the full range of .308" bullets from 90 grains thru 220 grains and more, just like it's big brother the .30-06.

What you will get is likely more penetration and bullet weight retention in the heavy game animals like moose and elk. More recoil, of course, and a slightly more arched trajectory with the RN bullets than with the pointed 180 grain bullets. It's my idea of a 200 yard maximum range cartridge, and is there to give you more stopping power on the big stuff if you are limited to the .308 Winchester cartridge.

Just thinking aloud, isn't the twist rate on most .308's a little slower than what you'd normally find in higher capacity .30's? Maybe being a little too slow for ideal performance with longer bullets?

.308 twist

The "standard" .30-06 rifling twist was 1-10", just as it was for the .30-40 Krag. This rate was decided on for the then-standard 220 grain RNFMJ military bullets.

Most manufacturer's use 1-12" twist, although the competitive target shooter boys like the faster twist for long range stability.

Either one is perfectly suitable for the 200 or 220 RN hunting bullets at short to moderate ranges discussed here.

granted i am in no way better than most on here about bullets an reloading
but why not go with a lighter prem. bullet at lesser weight
say like bonded trophy bear claw at 180 or an a fram or even a partition
seeing some of them in articals an from a lot of focks around here that might be your best bet an a little less kick an like they are saying about twist rate it will be more acurite

200 Gr. .308 load

Winchester made and marketed a 200 grain .308 load until about 1984 or 1985 so it is a viable load.I still have a full box of these.
Why they quit making them I have no idea but this load was at one time manufactured.

Yes, a 200 Grain Nos. Part. will work in a 308, at least under the conditions that you are hunting & what you are shooting. I assume that
the treestand hunting involves those wonderful Whitetails, but if Black
Bears are included, it still holds true. They may give you a little more of a
"smack factor", but I don't think they will give you anything special over a
180 Grain Nos. Part. in the 308 Case.
Concerning range, you say that all shots are under 150 yards & if you
are sure of this, fine. But if you have any chance of a longer shot,
consider the fact that most reloader manuals will show 2,400-2,450FPS
with the 200 Grain bullet . Nosler #4 shows 2,400 FPS with the 200 PART. at 300 yards the bullet is down to 1,900 FPS & this is the lower limit of predictable expansion & with a 100 Yd. zero you would have nearly
20" drop. At 150 yards you will have some frontal expansion but not very
dramatic unless it is a shoulder type shot because of the low muzzel vel.
There is another way with the modest .308 case to have your cake & eat
it. I am merely pointing this out as an alternate possibility. If your rifle
likes the Barnes 165 or 168 Grain TSX, that is. Exhaustive test have shown
the Barnes X to penetrate about 28 percent better than the same weight
PREMIUM LEAD TYPE bullet such as a Nos. Part. That means a 168TSX
will offer penetration about the same as a 200 Gr. Nos Part. I have seen
various stats. & some of my own testing that bears this out. Now you have
a bullet that will start at about 2,800 FPS with a good deal of shock, a great wound channel with no lost penetration & a much flatter shooting
load if you ever need it.
I like 200 Grain bullets & use them some, especially the 200 Accubond,
but in 300 Mags that have the capacity to push these bullets fast for a
flat shooting, wind bucking, hard hitting load at long range.
