Thread: .243 win, slightly confused

    .243 win, slightly confused

    OK, this week I need to load some ammo for a new rifle I'm collecting on Friday.
    I have two powders in the cupboard, a little Benchmark, and nearly full tub of BL (C)-2.
    Bullets I have plenty of Hornady 58 grain V-max and 70 or so Sierra 75 grain HP's.
    Looking at Modern Reloading (second edition) BL (C)-2 is one down from the top of the list
    for 55 grain Bullets, so would be a good choice, but it is not listed at all for 58 grain
    It does however reappear listed in the 65 grain charts, no longer at top of list but usable.
    How is this explained, or is it as simple as nobody tried it, can I use it at all on the 58 grain V-max ?

    Neil.

    not sure how to explain it fella but i would give both a try...
    i find benchmark quite good in many 22 cal rounds as with blc-2 which is really good in 204 but you won't go far wrong with a tub of varget....
    that's what my buddy an i use in our 243's works well with 58 vmax, 70gr noslers & 87vmax too but using vit 160 in my 105gr loads
    if you got it on your shelf tho give it a go...

    Having shot 243's for about 40 years and loaded for them perhaps 30 years . My favourite powder has been and mostly will continue being IMR4350 be it a 70 grain bullet or a 95 grain bullet .

    Bl (C)-2 starting load for 55 grain bullet is 43 grains.
    How would I get on with a 58 grain bullet and start load of 42 grains, that is the same reduction as listed for
    other powders that are listed for both 55 and 58 grain bullets ??
    (note: some of the powders show no reduction, and some even go up)

    it is a common issue with MRv2

    same for N160 and 75gr
    its there for lighter bullets and heavier ones but not 75
    I started with a load for the next heavier bullet up and worked up (in my case 85gr) as the starting loads for heavier bullets are always lighter

    It's not an issue with the book, it's because the powder maker didn't supply the data for that particular bullet. Use the data for the next heavier bullet.~Muir

    I've had great results in my .243 with Hodgdons H4350 - what is the difference (if any) between that and IMR4350 - on the basis that they are both owned by Hodgdons?

    Hornady have the info on N160 for their 75gr VMax and VV have one for a Lapua 77gr (but then that is their bullet as well)
    Its not like 75gr is an unusual weight, I guess I just expect reloading manuals to cover the majority of popular sizes

    38.6gr N140 for me with 75gr Sierra Blitz Kings, touches at 100m and at around 3200fps good for both deer and fox
