    H4895 308w

    Hi, I have just started loading for 150gr Hornady Interlock using H4895. I haven't found Data for this exact combination do any of you know of a source.
    I have found similar of 41.5 - 45.5 of another make 4895.
    I started at 41.5 then 42 then 43 then 44, this seems the best so far so shooting similar to factory federal classic 150 just 50mm higher.
    any comments would be welcome good or bad.
    as you may have gathered I am new to this. (following Lyman handbook)
    Does it matter that the overall length of the completed ammunition is not as long as the book recommendation. the bullet is pushed in as far as the crimp canular.
    thanks

    Most of the time, 150 grain data is 150 grain data. Especially when dealing with lead core bullets like the Hornadys. Hodgdon lists loads for both of these powders.

    As to the OAL. It's usually good toload to what is being offered for OAL as yo will get a slight pressure rise. It is NOT necessary to load to the cannelure, in fact, that is not there for crimping with that particular bullet. It is a structural device. If you are having no problems you are probably fine but I would load them out to the recommended OAL just for good measure.~Muir

    That explains it ! I didn't have pressure problems. would it be good to crimp even without a cannelure on the bullet. Thank you.

    You can crimp w/o a cannelure if you use a Lee Factory Crimp Die. You must trim to a uniform length to have it be of any benefit but I like it. I FCD crimp everything I can and don't worry about cannelures..~Muir

    Thank You every one, I had looked on the Hogdon website, I was unsure as I couldn't find for this Bullet, Thanks Muir. I do trim to length, so will crimp.

    I50-gr bullets in .308 Win, commercial brass...H-4895
    according to the Hornady manual 2013
    37.7 gr 2300 fps
    38.8 gr 2400 fps
    40.6 gr 2500
    42.4 gr 2600
    44.0 gr 2700

    A lot depends on the bullet. Some boat tail bullets will have less bearing surface and more velocity.

    If you can get it..
    44.0 gr IMR-4064 2700 fps
    44.0 to 46.0 gr of RL-15, Varget or N-140 will give you outstanding accuracy and 2800 to 2,880 fps

    When I read h4895 the 110gr bullet weight came to mind, them velocities southern has posted are very slow, am I right in thinking that bullet will expand properly when 2800fps and above
