Determining PF w/o Chrono

  1. Hello guys, is it possible to determine your PF without a chrono? :) I have ammo kasi for the match this weekend, but I'm not sure kung papasa cuz I changed the recipe and different din yung reloader. My current recipe is 4.7gr of VV N320, OAL of 1.17. My old load was around 4.6gr VV N20 with unknown OAL. I clocked at exactly 170pf. I added 1 gr. to be on the safe side. :supergrin: Does a change in OAL significantly change the velocity of the bullet? BTW, 180gr gamit ko na heads. :supergrin:
     
  2. Anong barrel yan dre? Kung schuemann o STI baka pumasa pa. But most probably minor yan.
     
  3. minor yan sigurado. gamit ko dati 5.0 n320 180 fmj 1.160 oal. ang pf ko around 176 to 182. bar-sto ang barrel ko.
     
  4. Lead ot FMJ? If you are using lead you maybe close to being major. My load for my 6 in benny hill as follows:
    4.7 grains 178 PF
    4.4 grains 171 PF
    OAL 1.190 VV 320 using 185 moly coated & STI 6 in barrel.
    TAke note that this is for a 6 in limited gun.
     
  5. that's not a problem, just make sure you shoot all A's!

    huwag mong gagayahin si pogi, puro Alpha Tango parati ang scoring!

    ala' tama! hahahahaha! :animlol:

    :dancingbanana:

  7. :sad: I had a thousand of these loaded!!!!:alex: :steamed:
    I shoot an STI Edge. Before kasi sa level 3 in Splendido, I barely passed with 4.6gr of N320, unknown OAL. So I assumed with an extra 1gr, for sure pasado na ako. 170pf ang minimum diba? Using Darth Board's load data, baka may chance I might squeak in at 170 pf hinde ba? (Correction 4.8gr of N320, OAL of 1.17 pala na pa load ko)
    I have some super hot loads from Truweight that clocks in at 187pf...which is TOO much for my taste.
    Any advice on what I should do? McO? Doc???:brickwall: Looks like I'm screwed!
