I have a Savage model 10 fp in .308 with 1:9 rifling
twist and was wondering if anybody's got any good long
range loads for a 220 grain Nosler partition?
thanks

WF,

220 grains is a heavy bullet to push from a case with limited capacity.

If you're defining long range as 800-900-1000 yards the 220 grain is going to be ill suited when fired from the 308.

At unknown distances your range estimation skills will really be tested, as the bullet falls pretty much on the vertical that far out.

Two very good weights for the 308 at 800-1000 yards are the 155 palma and the 175 matchking. Skip the 168 grain from Sierra, it's designed for 300 meter ISU shooting and sheds velocity real real real fast past 800 yards.

If you try either of the above bullets, repeat after me.........VARGET......Varget.......Varget.

Good luck

Nosler's own .308 loads top out at 200grs. Ditto Speer and Hornady. Hodgdon gives loads for 220's, but we are talking about 30-30 velocities out of a 26" barrel. I don't see the long range potential in them.

If this question is related to hunting heavy critters, I'd use 180 Partitions, Barnes Solids. If that doesn't cut it you may need more gun for what you are hunting.

I have loaded the Sierra 220 gr. RN in the .308 Win. Velocity was 2350 FPS, and I got 3/8 inch groups. Powder was W-760, Winchester brass, WLR primers. I won't post the charge on a forum, but I will give it out by E-mail if asked. Rifle, BTW, was a Win. Mod. 70 with 1 in 12 inch twist, 22 inch barrel. My load might be a tad stout for rifles with a faster twist.
Also, I think the Nosler partition might be to long to stabilize properly
Shortly after the turn of the century, a bit after 1906, the 30-40 Krag was considered to be a better elk rifle than the 30-06. This was due to bullet construction not being up to the 06's velocity. Now the Krag shot a 220 gr. bullet at 2000 FPS and was considered more than adequate. So why shouldn't a 220 gr. bullet at 2300 plus or minus 50 FPS not be just as adequate? Of course, you have to be a good enough hunter to "Injun" up close enough to use it. Are you?

ah ha Paul, how many yards with that 3/8s group? I get 8
inch groups with a Mauser 98 in .308 with 240 gr. match kings. I use a amount of H335, the barrel only has 2 groove
rifling, not accurate, its about 800 yrds to target 55 gal
drum, its supprising the damage this bullet can do at long range, can bust a cinder block at this range.

I've heard of people doing it for short range and getting amazing groups. I have shot a Savage 10FP at 1000 yards just for fun using a 190 MatchKing. It did pretty well. I believe I was using 42.0 grains of Varget with a 210M primer. I've seen people who molycoat use up to 44 grains with the 190, but that's pretty hot. 42.0 flattens the primer out pretty well in my Savage. Did Savage change their twist rate? Mine has a 1 in 10 and I was not aware they changed it or had a 1 in 9 option. Is it custom? It wouldnt matter as a 1 in 10 will easily stabilize a 220, just curious. I would tend to agree with some of the other folks that a 220 out of this case would be distance limited, but would probably drive tacks at shorter ranges.

Zot. My shooting was done at 100 yards. Frankly, I tried it because I kept hearing that you couldn't do it. That it would not have enough velocity.
Just for the heck of it, I just checked Sierra's ballistic tables. Using 2300 FPS, the 220 gr. RN sighted in at 200 yards is 3.3 inches high at 100 yards, 5.24 inches low at 250 yards and has 1545 ft. lbs. of energy. So you really don't have to get up that close for say an elk, moose, or whatever.
I still think that spitzers and spitzer boattails are too long to stabilize at .308 velocities. JMHO.

Thanks for the info guys, I will mainly be using
this round for Whitetail, but also I am also just
Experimenting with the loads to see whats best.

BR1000, As far as I know the rifle is off the shelf,
the guy that sold it to me said it had a 1:9 twist
so, I took a Dewey cleaning rod and covered a brush with a
patch, marked the rod and slowly withdrew it until it made
one complete turn..I did this about 10 times to be sure,
came up with 9.25 every time...do I have a unique rifle?

WhiteFeather,

It sure appears unusual, to say the least. Mine is a 1:10 and to the best of my knowledge, they still come from savage that way. 1:10 is the dominant twist used by all manufacturers and barrel makers who want to make certain just about any 30 cal bullet will stabilize. 1:12 seems to max out around 175 to 180 grains. Depends on the rifle. Even though Sierra may advertise otherwise, a 1:10 stabilizes a 240 MatchKing just fine. My 300WinMag 1:10 match rifle has even stabilized the old 250 MatchKing that was out in limited numbers during the 1980s. I still have about 500 or so of them. Whatever the case, you should be able to shoot a telephone pole out of yours with the right powder charge.
