I’m measuring velocity with a Chrono pal.
it’s always been dead on with drop to 600y with various load on various gun in the last 13 years.
and i was shooting alternately my 300win to let the second rifle’s barrel cool between groups. and the velocity is always the same with each load for each...
Hello everyone!
Last year i traded my left hand Rem 700 BDL in 7mm for a right and 270 of the same model for my daughter.
I unfortunately put it in the safe without much of an inspection, and now that i’m starting working on it, i noticed there’s pitting on the bolt face. No worring much about...
Hi!
i’m getting a new rifle in 300 win mag.
i managed to grab 200 180NBT in classified ad.
but the only suitable powder i’ve found is imr4831.
Anybody care to share their experience with this combo?
i’ve found lots of info about RL-22 and H4831 online, but not much with the IMR
Hi!
i will start loading for my daughter’s BLR in 7mm-08
i will load the 120gr NBT with H4350
the min coal for this powder with 120gr bullets is 2.800 as per my Lee manual.
problem is, the cartridge won’t feed reliably at that lenght, i have to go 2.790”
for reliable feeding.
now i loaded...
3100-3125 impact velocity, 45gr retained weight (35%)
shot into 1 milk jug, the following were windshield washer jugs, found in the fourth one.
not impressive penetration or weight retention, but impact velocity was pretty high.
this should work on deer
Well finally she ain’t just pretty, she shoots pretty good too.
60gr H4831 behind a 130 interlock Sp at 3145 average.
that should be good enough for hunting to 400-450 yards.
the two groups in the left side are new Win brass
the two on the right are once fired in that chamber and neck sized...
thanks Dr Mike
i was expecting a velocity closer to what i’m experiencing.
when i look at the 3139 fps velocity line, it reads 64000 psi
can i expect that this is about what the pressure is in my rifle, since it is the velocity i get?
Hi.
finally completed my load development with my Carl Gustaf semin custom rifle
it shoots the 130 hornady SP in about 3/4" with new win brass and 1/2" with neck sized brass.
average velocity is 3140 fps
can someone with quickload run the numbers for me?
i’d like to see what it guess the...
Thanks guys
would it be safe then to test from .010 to .040 from the land without backing the powder charge?
loads are already made...
that’s 0.010 longer and 0.020 deeper than the test loads
I recently started loading for a new to me 270 winchester
loading the 130 hornady interlock on H4831
first test was a ladder from 56 to 61 gr to check for pressure sign.
i forgot my chrono that day, but didn’t see any pressure signs.
following test was all 60gr loads with different primers...
shot it today with factory american whitetail 140gr btsp and i’m not impressed...
1.5" to 3" groups.
hope it will do better with handloads.
i should receive 130gr interlock flat base this week.
but i was still expecting a semi custom rifle to shoot better with anything, hopefully it just...
I’m about to reload my first round of 270 win.
I normally hunt in temperatures between 25 and 50°F
but it sometimes get to 0° and even -5°F
i have on hand CCI 200 and BR2, rem 9-1/2 M and fed 215.
Which would you start testing with?
