What was the bullet diameter of the Federal sp load?

**Yoda-Dad** · May 30, 2004, 13:15

unfired it is DIA= .309"+ (+ meaning a very little) LOA = .845"

Recoverd DIA/LOA/W , at that time i didnt record it . however , i still have a few in the 'tested collection' box and will re-shoot it the FED was around 2250fps @78F. but only 2120fps ave. @48F. i just lined up some waterjugs @50M and popped them to see if it would expand at all at the low velocity .

i figured out that , IF this PMC load was nominal SKS MV (2411fps) , the above test would equal a 155yard shot at the water jugs . AK nominal MV (2311fps) = 122yard shot . if i shoot it 'AS IS' at near 0 range = 107yard SKS shot .

i know there is a RPM diff but , from a ' stability factor' point of view , this is meaningless . the bullet is spinning with ~4 times the Stability Factor (1.5 needed) nessisary anyway all around .

i'm gonna load a few PMC bullets UP to ~2411fps to see how they hold together at near 0 range .

hey JA , shot 2 FED factory loads .

unlike the last times @50/100M , shot these at the jugs @50ft. shots went 2169fps and 2161fps @15ft.
a first for me , both retained jackets but , one ofem is 'rattly' .

IMO these are 'overexpanded' for large game hunting bullets at this low a muzzel velocity . hit the jugs about 2130/2120fps as per JBM.

RW = 94gr / 102gr
R-fd = .6 to .7" with jagged jacket edges rounded off . lead in the middle .
R-LOA = .380" / .370"
UNFIRED LOA = .845"
compare these recoverd dimensions to the PMC bullet below !

both did the 'overexpanded water dance'. 1 exiting the rear-side of jug 3 (4-5.5" jugs in a row)and found laying on the ground 3feet farther . 1 hit the forth jug on the corner an BOUNCED OFF forward and to the right a couple feet . had i not saw the glint of it going , woulda never found it . cant believe a bullet could bounce off a flimsy milk jug !
jug 1 and 2 destroyed , 3 just a hole

if they would load this bullet to standard velocity it would be an excellent S/D round . the ratty jacket edges are sharp all-around .

have 2 more left , HMMM . what to do with'em .

WARNING - these reloading practices not generally recomended . dont go adding powder to factory ammo willynilly ! i have a lot-o-resorces , experiance and a chrono ! your lot of PMC will probly be different

shot the 125grn PMC PSP at 4 waterjugs lined up @50ft. 20"B , 78DEG.F.

this first shot was just the factory load , 2199fps @15ft. (its like 10 degrees warmer than the chronoed 2112fps average . very temp sensitive powder? or just within the 117fps ES ? ) . strait through the 4 jugs (22") and recoverd from the softsand backstop laying on the ground like you threw it there . jugs 1-2-3 blown open . #4 just a 5/8ths inch denthole that drained like a hose stream out the front while standing there by its self .
hit them at about 2166fps .

RW = 118gr
R-fd = .520" to .550" flat button head . edges hardly rounded off at all .
R-LOA = .480"

next shot was re-loaded with 3 grains more PMC powder (still mild pressure signs on brass/primer)
2327fps , hit the jugs at 2294fps . basicly the same effect as the first shot but more splash in 1 and 2

RW = 112gr
R-fd = .540" to .560" . same very flat expanded end . hardly any rounding off at the edges .
R-LOA = .460"

after this i realized i didnt bring enough water jugs , hadnt planed on 2 shots with the Federal . [img]redface.gif[/img]

a Factory PMC with 4 grains more powder did 2430fps from the 20"B @15ft. still showing mild-normal pressure signs .

this is an unknown fantastic 762x39 deer/large game bullet . every shot showed that the bullet gets maximum frontal diameter hitting the first jug then , is of the correct shape to drive that flat tipped diameter straight through 22" of water , with almost nothing left after that .

to bad ya cant buy them seperatly .

somehow i screwedup and managed to shoot the FED factory load again , exactly the same way as the above 2 FED shots already !?! with the last of my milkjug supply . 2180 fps @15ft.
RW = 101.4gr
R-fd .620" to .660"
R-LOA .390"

this shot hit lower in the jugs than i like . that blewout the bottoms of the first 2 . because of this the bullet tipped sideways and slipped through jugs 3 and 4 that just got dentholes in them and stood there draining . bullet barly made it to the sandwall backstop 3ft. behind .

again , i have to say , this bullet would be destructive as heck @full speed . i wish i could find a way to get a pic of them for you .

the jackets seem to curl out (8 strips) , then back against the shank and support the frontal diameter . guess they stay together , jacket/core , at higher velocities than what i previously tested them at in waterjugs .
