H4895 is too slow for a 55 grain bullet, and TAC might be, I don't know.

I have used nothing but WW748 for the past 40 years in the .223 with 55 grain bullets, so if it was me, that is what I would use.

It will give you about 200 FPS more velocity then H4895.

I can't afford to shoot Combined Technology Ballistic Silver-Tip's so I can't help you there.

i was just going by sierra's reloading book.. they ask for h4895 for all their 55's and on the list of powder speed i found it right next to w748 and h335

Well, I could be wrong then.

I just like WW748 because it is ball powder, and it goes through powder measures and .22 case necks like water.

The stick type powders like 4895 tend to bridge over and hang up in .22 & smaller case necks.

my powder measure sucks, so i weigh and load each by hand... talk about time consuming...

To add to the discussion, in looking at this (http://www.reloadbench.com/burn.html) Powder burn rate chart, assuming it's accurate, out of 173 powders, they have ten powders between them, so I'd guess they're quite close in burn rates.

Listed max for H4895 in 223rem with 55gr bullets is 26gr and 26.3gr for w748, from the hodgdon reloading data center.

W748's data seems a little on the light side as it has lower pressures than H4895's starting loads.

I like to use H-Benchmark(25.6gr listed max for 55gr bullets), as it's a fine short grained powder, and meters well in my powder measure.

I know some others who like H-Varget(compressed 27.5gr max for 55gr bullets). But it is a larger gained powder, which doesn't meter well in some powder measures.

357,
It's hard to tell which powders have the same burn rates going by that chart. try this one http://www.adi-limited.com/handloaders-guide/equivalents.asp

And i always had the view that ADI-AS30N was slower than Bullseye, about the same as Red Dot.
So it's strange that they list AS30 at #4 and H-Clays at #16, with Bullseye & RD in between. I understand that various powders may differ in burn rate in various calibres.

H-Clays and ADI-AS30N are the same powder, though. http://www.hodgdon.com/PDF/Hodgdon-Clays-Universal-International.pdf

I've been using AS30/N & AP30 in pistol, shotgun and rifle loads for many, many years, and I believe that site may have inaccuracy in some of that data table.
