The Speer 300 grain Gold Dot is no longer made in .451 - they changed the nose configuration it 2 years ago and it now made as a .452. They (speer) does offer a .451/300 grain but it is not a Gold Dot, it is a Uni Core bullet. The .458/300 grain is also a Uni-Core bullet.

45 Revolver UCSP 45 Colt HV

45 cal. Flat Nose HP (45-70; 450 Marlin)

This is the Gold Dot...

45 Revolver Golt Dot HP 454 Casull

I can not find the listed velocities on the Speer site but you can look up the velocities of the gun suggested and come up with a good idea.

Here is Gold Dot spec sheet

Hope all of this posts....

I like the Speer .458 HP which I think is Uni Core. It is a 300 grain and out of an Orange MMP sabot is very accurate. I have not shot anything but Sabotloader was explaining to me that this should be an excellent big game bullet.

I am - and also the the 250 Gold Dot for deer - there are a lot of peopleusing these now... CG even uses the 300 grain from his rock sparker... The Gold Dot is a 'poorman's' Nosler Partition.

That .458 Special Purpose bullet that Cayugad found (built for a Marlin 45/70) is a Uni-Cor ( bonded ) bullet and it would be an excellent bullet even for big biggame. I do not know how Dave found this bullet but it was a very good discovery and from his tests - it shoots very well + plus it is a rifle bullet builf for hunting... and I do not know about you but any time I hear 45/70 I am thinking Buffalo stopper even though I know they used a heavier slug...

Sabotloader- Your data file post, is that from the reloading book or did you find that on line?

It is not from a book - I bought a ballistic program from Barnes several years ago and have it installed on my computer...
