Doubt I will see this with cast

I love cast boolits and have a few rifles that see cast exclusively but still use J-words.
This is one of the reasons why, not bad for a 24" barrel and no it isn't a 17, 20 or 22cal.

[RobS]

OK, Ill bite............what are you shooting there; I bet the throat is short lived with such velocities.

[MBTcustom]

Ill take a guess.
300winmag with 110-150 grain bullets?

Barrels are expendables. That rocks!

[reed1911]

6mm/284?

[tazman]

300 Weatherby magnum will do that with 110 grain bullets. I used to have one years ago. You wouldn't believe the muzzle flash from that combination. Blindingly bright even in bright daylight.

A 55 gr. .224" cast bullet in a sabot and fired in a 30-06 will do that and more....:D

Light bullets in .243 will also get there.

240wby, they are available in the vanguard so cheap shooting, picked mine up new for less than the cost of a rebarrel here in Aus.
Don't expect barrel life to be great so have kept testing to 3 shots, last 2 loads tested both clocked over 4000fps and accuracy actually improved as velocity increased. Last 2 loads went 0.61" & 0.52".
For a budget sporter weight rifle Im happy, should make a heck of a walk about dual purpose rifle, 100gr are still scooting along at over 3200fps and shoot to almost exactly the same point of aim.

Hadn't thought about sabbots and cast, might make a very interesting project further down the track.

My Chrony acts up like that some times too.:rolleyes:

yeah does tend to read a bit slow:kidding:
Swift is almost due for a rebarrel, have been thinking a 28" improved chamber, 4500fps easy might even see 5000fps with the real light weights.

[Hamish]

Can't speak for anyone else, but my experience with the 22 boolit in the .30 sabot resulted in very poor accuracy and melted white plastic strung from one end t'other. Blech.

We've seen close to 4500 with 40gr in 22-6mm Akley Improved. Definitely not barrel friendly. Only did it for kicks.

I'm pretty sure mid 4000's is the limit for smokeless powder. That is as fast "normal" gun powder can shoot a bullet and stay within pressure limits. That is why the military is working on magnetic guns and such.

When I 3nfered the reloading life style, I had to have some sabots for an 06 very fast I envisioned long range coyote hunting, accuracy never got better than minute of paper plate and what a mess, a few years later when hill country rifle did some work on that rifle they asked what all the small bits of what looked like plastic were.

Mine too. I had three of those things before I got the Pact I have now. I'll never buy anything with the Chrony name on it again.

[Motor]

I was joking about the Chrony. It's nice to see "220" got it.:)

The only real trouble I ever had with mine is when my brother shot it with a 50 caliber muzzleloader. I ended up with a new model. Of course my brother had to pay, half price I think.

One of the blokes on a aussie forum I also hang out at has a couple of improved swifts runs 40gr at around 4500, both are getting close to 1000rds and still shooting better than 1/2moa at 400.
Have seen reports of 4700+ with improved swifts and 36grs, there was a kiwi that used to post on some of the aussie forums that had seen over 5000 with light pills in a 22/243 improved.

I'll bite, 6mm-06 with 58 grainers?

close 240wby & 55grs

Cant say the old crohny has given me any trouble over the years, must be about 20yrs old and apart from a fresh battery every year or so that is it. Only modification has been a piece of Perspex to give a little protection to the LCD readout from muzzle blast, lube etc. It has been blown over quite a few times by muzzle blast but hasn't taken a hit yet.
It is one of the early ones and does nothing but display the shot velocity, next shot replaces the previous one on the readout, might be why it has been so trouble free. Have checked it against a few other brands and it is on the money.

There I go thinking wildcat when 240 Weatherby should have come to mind!:-) You are definitely haulin' the mail!

I have a glass microscope slide over the readout screen, affixed with clear Scotch tape. Keeps unburned powder grains from holing the thin plastic over the LCD display. Readily replaceable if something cracks it.

[44magLeo]

I have a Chrony. The Master F-1 No need to do anything to protect the readout. It sets up on the bench. When I got it I thought it would be much easier to read the display if it was closer.
I also picked up a Chrony printer to help keep track of the info. Just print it out and staple it to the target.

Mine too. I had three of those things before I got the Pact I have now. I'll never buy anything with the Chrony name on it again.

I wouldn't put much faith in that Pact either. If you are going optical, Oehler is currently the only name with accuracy.

The others are good for general reference and that is about it. Which is still quite valuable. And, I'm not knocking the "others", I own to Chrony's, Caldwell, etc.. They are convenient, and still see plenty of use. But if I'm chasing single digit ES for a comp load the Oehler is the only one I take.

[Frank V]

I use a Chrony a lot, but I'm only after velocities & the ES not doing tecnical things with mine. It's accurate enough for me.
I have a Pact also & one time I put the Chrony on the frame the sky screens of the Pact are on ( between the start & stop screens) so the Chrony would read the exact same shot as the Pact. They were within 7fps of each other. The Chrony is much faster to set up so I'm using it the most.
