What 100gr bullet have you guys found to be the most accurate?

For hunting or target shooting? Just load up some TSX or TTSX to SAAMI COL. I've had luck enough just doing that in all cartridges......for hunting.

Sorry, it a hunting round that I am looking for.

I have had outstanding accuracy and killing power from both the Hornady 100 grain sp and the Nosler 100 grain BT. I like the price of the Hornadys better.

Most accurate is the Sierra 100 gr. MK, the one I use on game is the 100 gr. Hornady IL. Muddy

100 TTSX is THE bullet for the .257 caliber of rifles.

Tested a custom today with several different bullets. The Sierra Game King and Barnes TTSX were both impressive.

Not for a 14 twist 250 Savage. Or a 25-20. Would be real suspect in an old 12 twist 257 Weatherby as well.

Minor technicality/qualification. There are 80 Gr. TTSX's out there, too.

25-20?.......Don't think many of those guys are going to even think about pointy bullets.

100 grain hornady interlock. Have made a lot of peoples 25-06s that "don't shoot" shoot amazing with this bullet.

But where can you find them??

Nosler 100 grain Ballistic Tip, accurate and deadly.

100 grain hornady interlock

Not really. A blanket statement was made which was far from correct.

There are plenty of bolt action 25-20s for which spitzer bullets work well.

I like Barnes bullets just fine, but they are completely unnecessary on deer sized game, which is the standard hunting fare for most 25s.

I've also had better luck overall getting the 100 grain Matchking or 100 grain Speer HP to shoot really well in different 25s compared to the TTSX. Not that I would recommend either of those for big game, but they shot the best, which was the OP's question.

Somewhat off the subject, I tried 115 VLDs in a 1894 25-35 sometime back. I figured it was worth a try. Shot freaking awesome!

Sorry. I was thinking 25-20 was mostly lever action.

And Barnes do waaaaaay overpenetrate!

Winchester and Savage both made bolts, and Savage made a single shot in 25-20. Probably a bunch more that I don't know about.

The round was hugely popular in the first half of the 20th century, and though we don't see them around a whole lot these days, plenty of perfectly serviceable rifles are still sitting in people's closets.

I would like to have one of those pump action carbines. Somebody sold one on the classifieds recently. Would be FUN!

But that would require the non-pointy bullets.

I pulled the bullet starter off the false muzzle of a Stevens and not sure how well the Berger vld would fit.

That was a fun little rifle.

Yep. That WAS you. That was a nice package you passed along. Almost said the magic words. Haha.

I seriously considered it as well! Cool little rifle.

The 25-20, 25 WSSM, and 256 Win Mag are the only factory 25s I haven't messed with; I should have bought that little pump just to check one more off the list.

Though my interest in messing with a WSSM is on the same level as hitting myself in the junk with a ball peen hammer. So I probably won't be completing the 25 experimentation anytime soon.

For the OP it started and ended at the 100gr TTSX in my vangaurd

I had a 25 WSSM and foolishly sold it along with my dies and brass. Great cartridge, but I chose to keep the 25-284 instead....and recently foolishly sold it!

Better nip that business in the bud!

I've had good luck in 25-06 and 257 Roberts with the 100 gr Hoornady soft points and 100 gr TTSX. My preferred hunting load is the TTSX.

100gr partition

The 100 gr Hornady SP WAS always my favorite, but since Hornady has had them " temporarily suspended" for a year and a half now I've had to move on to other things.

Just loaded 50 100 grain Sierra flat base.. Will use them on a whitetail hunt next mth.. Hornady's also work well as do partitions.. The Sierra's have always been super accurate for me.

Sierra 100gr. MatchKing.

Shot several head of hogs with them too. Just don't expect an exit.

100 grain partition has worked well in a number of rifles. Have been impressed with the E-tip as well. My Montana loves the 80 grain TTSX....

I have yet to see a 25-06 that didn't shoot the 100 NBT well

100 grain GS Custom HV's are the cat's meow in my Roberts.

In antique lever action 25-20, I clamp a pistol scope to the barrel and shoot Sierra 75 gr hollow point 1600 [short bullet that can stabilize], 1.895" OAL [too long to feed, must be loaded single shot] with 12 gr LIL'GUN does 2350 fps. I have to keep the pressure down to 28kpsi or the primer will pierce with the sloppy firing pin to firing pin hole fit.
That shoots ~ 2.2 moa, which is good for an antique.

For modern big stuff, the 75 gr Vmax at 3500 fps can shoot in the .4s.

But for mule deer bucks, I like the Nosler 115 gr Ballistic tip at 3050 fps.

I haven't either...that said I've found that I can make a ballistic tip shoot well in just about anything. I also found that the 100 grain interlock and the 100 grain sierra flat base shot well in my 25-06.
