The bullet you are looking for and the one that Cayugad is pointing out are different bullets... If you want the 452/300 grain Gold Dot - go to the Speer Website....

http://www.speer-bullets.com/

Choose > products
then > Bullets
then > Gold Dot
then in the middle of the page > product listing
then scroll down to #3974 300 grain bullet for 454 Casual.

So the product number is 3974

To get to the bullet Dave is talking about which is a .458 (45/70 bullet)

Choose > products
then > Bullets
then > Special Purpose
then > Product Listing
then scroll down to > #2482

Speer does not make any rifle bullets that are Gold Dot's, but this bullet is made as a Uni-Core bullet - which is much like the construction of the Gold Dot.

Now I need to go back and read if this what you wanted and has it already been pointed out...

Hope I have not confused the issue...

The Gold Dot 300 grain is a very good bullet and is 45 cal
The Special Purpose bullet is also a very good bullet designed for the Marlin 45-70 Rifle.

OK - I'll add a bit....
The .452/300 Gold Dot in a HPH-24 Sabot or Harvester Short Black should measure something close to .502-.503

The .458/300 Special Purpose in a MMP .457-.458/50 cal Orange sabot is closer to .503 - .504 in diameter - but the sabot is really forgiving and will go down most .502 barrels
