I am looking for a new bullet for my Triumph, has anyone used a Sierra Gamemaster .451 300gr bullet?

If you are looking for one of the less expensive bullets that might work well for you, I would suggest you take a hard look @ a Speer Gold Dot - either the .452/250 grain or the .452/300 grain.

The 250 is an outstanding bullet for whitetail and can be easily shot to 175 yards without any sight adjustments. The 300 grain is really a great bullet and can be shoot to 200 yards. My only hestitation is the 10 to 25 yard shot where it MIGHT not open as fast as the 250....

When hunting whitetail in my ciuntry I would easily select the 250 grain, with it's deep HP it opens quickly and because it is bonded it stays together and drives all the way through the animal.

If you are looking to move to what they call a 'premium' (because they cost a lot more) my choice has traditionally been a Nosler Partition .451/260 grain... it is deadly really deadly... HOWEVER, I may change may choise after this years deer season. I am trying a new bullet this one of the new Lehighs - they are accurate... and the reports of their terminal performance are really over the top - just do not know myself from first hand information...

Hey! welcome to the forum - it is a great place to hang out...

welcome to the forum. I never tried that bullet. Nor that rifle. Good luck. Sabotloader gave you some good advise.

Thanks guy I have been lurking here for awhile, lots of good info. Is the 250gr enough for black bear over bait? I am possibly going to take this next spring. Other than that it will be for deer at ranges less than 100yds.

I rate it as an outdstanding bullet for most any animal @ 100 and less - for thin skinned animals such as whitetail you could almost double that range - especially if you shoot it hot.

I would think the 250 over bait on BB would really do the job...

Here are some pics of the 250 after I dug them out out of a wet clay water bar...

Thanks again for the great info. Also, with the tight bore on the Triumph which sabot will load easier a MMP 3 petal or the Harvester Crushed Rib? I have read both ways. I could not get a shockwave down with supplied black, it will go down with a yellow super glide but I really have to stand on it.

I think I have an 'odd ball' Triumph - I can load the HPH-40/50 Blue, HPH-24 Black and the HPH-.458/50 Orange very well.

The Harvester short black is much tighter and the 'crush rib' loads very well.

Other than that can not tell you much....

250grn T/C Shockwave with Harvester short black sabot and 110grns of BH209 is pretty hard to beat as far as accuracy in a triumph.

If you want accuracy and performance just pick up some 250grn Lehigh's and the bullet will take care of the rest.

Welcome

I buy bullets where I can find them.
Here's a variety that I bought partial boxes of.
The 405 grain Winchester flat soft point (bottom left) looks
like it would be a bruiser for both the shooter and the game.
