Thread: 300 blackout

if going to use supers /factory ammunition and reload your subs...you just about the same or indeed better off to use a 7.62x39mm and yes you can use .308 projecties in them to good effect..said it many times before,the x39mm is a 150yard rifle/cartridge so you dont require 1/4" accuracy...a 2-3" group /pattern will do chest shoulder shots with ease out to that range...but like others have said,the novelty wears off when deer are at 200-250yards.

Thanks ! validation of the conclusion I came to when I grabbed a Howa Mini in x39, chopped to 16" added a DPT and a red dot - light weight quiet and ideal for goats and maybe deer in the Marlborough sounds bush I reckon - ammo darn cheap too.

30tc/ 308/ 30-06 /300wm too
theres nothing special about a 300blk to make it push a 30cal pill 1000fps

if you are able to handload any of your 30cal rifle will do exactly the same as a 300blk
and with trail boss it is so simple

The hard part is finding Trail Boss,
I have just had a .300 BLK built mainly as a cast bullet test rifle and a small game rifle I don't own an accurate .22RF
and I don't want to waste Trail Boss, 3.5 to 6.0 grains of any fast Shotgun or pistol powder will do for sub loads
the expense is in the primer.

I know where a big pottle is of it just around the road from you...99% sure the owner would part with it ...or most of it to you....

Thanks for the heads up but I don't use it that much anymore, I have a enough powder to last quite a long time,
I will run out of primers before powde.r

Yes indeed, been using some old ICI Nobel Shotgun No78 powder for exactly that. 12-13 gns max in my old 303 gives 1600-1800 fps with Walker 215gn (approx) gas checked boolits. Accuracy is not outstanding from the old girl but will hit and drop minute-of-goat out to 80m no problem.
10-12 gns gives around 1400fps in my Marlin 30-30 with Walker 151gn GC HPs with better accuracy. They hit pretty hard too. Neither is suppressed- don't have much interest personally in subs other than for rabbits with 22lr. More interested in emulating 19th- early twentieth century woods style hunting for table meat out to 120m with least wastage. Think 32-40, 44-40 for e g. Whitetail size ( Fallow, Goats, here) and 30-30 for the bit bigger ( Sika, Reds, Pigs)

Provided you have the twist rate to run the heavier projies, which most 308s etc don't.

i used the standard tikka 1-11 in 308 and my brno had a 1-10 and stabilisation is not an issue with hollow point cast bullets till the went over 180gr

with the 151s exiting everything i dont see the need of putting more energy into the bank behind them

Id be very surprised if the 151s didnt stabilise in what ever you currently have

You are correct the reason I bought the 151 HP mould was because it will stabilise in standard .308 twists also it was designed sperficly for the .308 Win
if crimped at the crimp groove the Gas Check is inside the neck,
I already had a 200 grain FP that people have trouble stabilising in 1:12" twist barrels at subsonic velocity
I still get asked for heavier .30 cal bullets; But there is no point the 151 HP exits on heart lung shots the only recovered
bullets are from longitude shots and 100 metre shots,
A few have shot two goats with one shot at close range,

The slower twist works better for lead bullets they can't handle high RPM, My .30 cal Cast Bullet rifles have 1:13" twist barrels
and shoot accurately at 1800 -1900fps with bullets soft enough to expand
Hard cast do not expand cast bullets have been shot to 3000fps but are like FMJ's totally useless for hunting
