Can I use the 50gr Sierra Blitz 1340 through my .223 1 in 8 barrel?

[Geezedtee]

Hi from the UK where bullets/projectiles are scarcer than Unicorn poop. Need some advice please.
I bought these bullets (green box No1340) to shoot Hares -we are overrun by them. Doing some reading prior to reloading and the Sierra website said "should be used only in “conventional” twist rate barrels (1×12″ or 1×14″). Confusingly they also said "Designed for velocities below 3600 FPS"
I've got a 20" barrel 1in 8 twist. So, according to PMax, my max velocity with Vit N130 powder is going be approx 3350fps
Question for you Guys: Will these bullets blow up on exiting at that speed?

No worries on those BK blowing up at that speed. But they will blow up big time on those rabbits...hope you don't intend to eat them
As they say here in the south..
JUST CHOOT EM!

Will be flip of a coin, likely the quality/condition of the bore will be a factor as well.

IME, the 55s are better performers in my 1x8 223 than the 50s, but I suggest you try anyway. Each barrel is an enigma unto itself.

We don't eat the heads
Shoot them at night using thermal scopes. Ranges 100yds max. We process them for consumption.
The occasional one goes for stew LoL.

It's a new Tikka Roughtec stainless. Hope the name isn't a clue

He’s not talking about the BlitzKing, he is talking about the old style Blitz (1340)

Yes, they're the ones.

Thanx...good catch

You could always back the load off a bit. I use the 1340's in my 222 at around 3000 and have had no complaints from the bunnies. - and it's a 1-8 twist.

I used the old 55 grain Blitz in a couple 222s years ago. Those bullets are extremely explosive and a varmint hit with those usually looked like it was hit with a 22-250. The same goes for the old Hornady SX (super explosive). Either of those old style bullets are over looked these days. Pity.

All I’ve shot for over 20 years in my deuce. Hard to beat. Dont know about 8 tw tho. Try and see.

Thanks. That's reassuring. The 3350fps was a predicted max load using Pmax but I prefer precision over speed so hopefully will get a good load before reaching that. Also prefer a 100% powder burn for night shooting.

I have found a great bullet for Jacks and Yotes to be the 55gr. Barnes MLE. Long for weight as it is lead free, the bullet responds very well to a faster twist, has superb accuracy and is very active on impact.

I've shot a lot of 50's in my 1-8's but the vast majority of them have been Hornady Max 50's. The Sierra Blitz Kings I've used in .223 have been 55's.

Its not the speed, its the rpm that blows them up. Email Sierra and ask them.

I’ve shot a lot of these in my 1-14 twist 22-250 but loaded them down to 3400 (by the book). I’m certain they were slower than that. Load some up and try them, you’ll know pretty quick!

Velocity can play a factor, as with more speed, the more heat generated on the jacket

Definitely maybe. The #1340s on the shelf here read "Blitz medium velocity". I've used them successfully in a Swift & 22-250 Ackley at over 3900 fps, with a 14 twist. You can do the math for the rpm generated, or just try some.

The Hornady 50SX is one of my favorite 223/556 AR bullets for critters. I run them in 1/8 and 1 in 9 barrels, at book max. Fox,raccoon, coyote and smaller targets. Makes for nice short coal, great for magazines as you can still play with seating depth. I imagine the Sierra bullet would be good if not for the rev limit.
