Thread: found the limit........

  1. #1

    found the limit........

    I have been loading for around 2 years now and never really seen the need to run hyper hot loads and as such never really needed to get close to stated max loads.

    luckily my rifles have obeyed the law of the sod's and not had odd chamber preferences...until now

    .222rem
    Norma Brass
    CCI400 primer
    N133
    43mm case
    OAL of "about that much"
    52gr AMax


    VV data states:
    3,4 52 HPBT Sierra 54,0 2.126 N120 1,16 17.9 876 2874 1,27 19.6 957 3140
    N130 1,28 19.8 899 2949 1,38 21.3 975 3199
    N133 1,37 21.1 916 3005 1,50 23.1 998 3274

    Their Max data shows 23.1gr

    I normally shoot 50gr VMax and tried three of these as a cvomparison. (centre group, lowest one was the first AMax which I lost and thought had gone over the target som moved POA to lower cross and continued)

    I was being a "good reloader" and worked my way up from 22.0gr in 0.2gr increments
    all going well when I hit the wall on the first one of 22.8gr
    Bolt was very stiff, case came off the extractor and was well and truly stuck in the chamber.
    The case has a clear pressure mark on the head, very obvious brightening marks along its entire length up to the web

    Just posted it to show you don't need to be near max to have pressure signs and the jump in signs was all or nothing.

    you know Ed, I was reading VV's loading data last night, and N160 for a 100g pill in .243 is recommended at max 39g (ish), but when I look on the likes of reloaders nest and such, most people are shooting 41-46g's of N160,,which according to VV, is WAY over max.

    makes me question VV's load data...

    ths84 on here had a similar issue with VV data when he started loading for his .243. Halfway through the load testing, going from min up towards max he had a very heavy bolt and a hard extraction. I agreed when he opted to stop there !

    the load data you are quoting was used using a sierra bullet your using a hornady bullet,this could be the cause of your over pressure as different bullets can show different pressure signs.
    Vit data can be a liitle on the high side though,hence work it up

    could be
    I use there data for three calibres and 9 weights of bullets, very few are the brand quoted.
    never hit a max on any other load.
    indeed the 50gr VMax load I have for the .222 is based on this:

    3,2 50 SPSX Hornady 53,0 2.087 N120 1,20 18.5 896 2940 1,30 20.1 964 3163
    N130 1,30 20.1 912 2992 1,39 21.5 986 3235
    N133 1,38 21.3 908 2979 1,49 23.0 979 3212

    which looks remarkably similar to the 52gr data!

    interestingly (or not!)
    Lee Max for 100gr .243 is 43.6 and the old VV data is 41gr

    with any published load they usually air on the side of caution for legal reasons,you can usually go way above published max load data,persoanlly I find the max load for the given powder iam using first then back it off
    may i ask why you shot test loads off sticks ?? as this will not help you decide which is the prefered load for your rifle as your not staedy enough to see any difference

    I would ordinarily shoot of sticks in the field

    It seems futile to find a load that shaves 3mm off a group on a bagged bench rest and then shoot off sticks.
    the .222 is not a range whore its a utility rifle.
    I want 1/2"-3/4" groups off sticks at 100+ ideally 1" high for a 225 MPBR.
    I have yet to shoot a fox at over 175yds (99% of them are inside 100yds)

    I am happy with any one of the three groups middle (50gr VMax), left and top (52gr AMax)
    Anything else is ballistic masturbation
