I got me a few lbs. of H4895. looking threw my manuals and found that its only listed for "light for calibre" bullet weights.
what is the reason behind this. If I use its for heavier bullet weights will i start seeing pressure signs before I reach proper velocity's?
 
What is your bullet type and weight that you would be using? For instance, I use 168gr. HPBT match Hornady over 42.gr of H4895 with MOA or better at 100m with my factory Remington 700 SPS with heavy barrel.
 
Check the Hodgdon website. They have data for H4895 in .308 for use with Hornady 208gr AMAX. I'd hardly call that "light for calibre".
It also works wonderfully pushing 500gr bullets in my 45-70.

If you are looking at big magnum cartridges then yes, it only worked for lighter bullets because it isn't a magnum powder. But for cartridges in it's ideal size range it works for ultra light bullets all the way up to heavy weights.
 
.243, 30-06, 375Ruger

my lyman manual dose not list any loads in those cal's with H4895

Hornady manual

.243win only list H4895 up to 87g bullets.
30-06 only list H4895 to 130g bullets
375ruger no H4895 loads

what I am getting at is when I glance threw my manuals I notice that in some cases H4895 is not used threw all of the bullet weights in a given calibre.

just wondering why?
could i used IMR4895 charges as starting points with H4895 and work up

Just because a manual doesn't show loads for a particular powder doesn't mean the powder is not suitable, that's why I have about a half dozen loading manuals.

H4895 and IMR 4895 are very similar but not identical, check the Hogdon website for H4895 data. For non-magnums H4895 is very versatile.

H4895, like all medium-fast rifle powders will not produce the highest muzzle velocities (i.e. "is not suitable") for heavy-for-caliber bullets for most rifle cartridges. Where it is suitable for heavy-for-caliber bullets is when the case capacity is small (e.g. 32-20) and/or the bore size is large (e.g. 458 Win Mag).
 
I use 69gr H4896 behind 300gr TSX's in a 375 H&H. I'm sure the Ruger can do similar, however case capacity and dimensions etc might change the pressure curve enough that it's not suitable.
 
check out steve's pages..............just google steve's pages.........more info there then you'll ever need including loading data for the obscure and antique, he pretty much covers everything and anything............
 
I am no expert but I should think the reason that H4895 only offers loadings for lighter weight bullets would be that the burning speed of the powder is too fast for heaver bullets. The pressures would go out of sight before the round left the muzzle with heaver bullets.
 
Andy's post explains it well.

These things are generalizations, however.

I use IMR 4895 to load 220 grain RN in my 303 British, for example, wich is contrary to theory. Sometimes, if you are running out of powder capacity, you need to go to a faster powder, rather than adding more slow powder, since you simply can't.
