Re: chronograph's

I think this is gonna be more of a personnel thing. I have a Pact MKIV, only one I've ever had. Been working great for close to 20yrs. It's called a championship timer, but has a cronograph. Also balistic takes the dats you feed in and gives back balistic data. I shoot against that data and the data is really good.

Re: chronograph's

If you are a weekend reloader / ballistics player (like me) I suggest a Beta Chrony
If you really get into it, you can send the rig back to Chrony and they can upgrade it to the Beta Master Chrony with remote LCD reader pretty reasonably.
Will tell ya what ya want to know.
Down side is the entire unit is housed with the screen assembly, if ya hit it, it's likely toast.
I've had mine for years with no problems, just take care when lining it up.

If you are gonna be serious, Ohler makes a great machine, but then you'll want a device to measure chamber pressure, an indoor range, etc. Yes

I have never used a Pact unit, but understand they work well.

Re: chronograph's

Thanks 233d--I am somewhere betwixt a weekend and serious loader- been at it for 20+ yrs and do all my own stuff- shoot maybe 1500 rnds a year of different rifle cal plus handgunsd-so I just thought it mght be a good idea-- the one you mention is priced ok-and is at cabela's so I can grt it with points- just finished a new shooting table so with two i can use one for Chrono and one to shhot from. Thanks.

Re: chronograph's

If you decide on the chrony, ya only need the screen shades on bright sunny days. Thats the shades the metal rods hold up over the readers.
I try to run my numbers on overcast days so I don't need them. The rods are just there to hold up the sun shades, but they can also provide a verticle reference point. I replace the rods with cocktail straws so I maintain my verticle reference point and don't ruin anything if a wayward bullet strikes a straw. You can imagine what might happen if a bullet going mach + wacks a metal rod. When sighting the across the unit, I place the vertrticle cross hair dead center of the unit and the horizontal cross hair resting right on top of the cocktail straws.

Another trick is to build a sort of steel V, point toward the shooter, to place in front of the LCD read out on the front of the unit. If a bullet is low, it will skid off the ramp out of harms way and not ruin the machine. This is a must if you are chronoing shotgun loads, the wads can come out with enough force at short distance to damage the unit. Some wad types break away pretty fast.

Good luck

Re: chronograph's

I bought a CED Millennium three years ago and have been well pleased with it. Bit on the pricey side compared to some of the others but I liked the remote processor/display.

He used it three years in a row to do various science projects with rifle rounds. In case anyone is interested the following is what he did.

The 1st year he compared % of velocity changes with 4 powders and 3 load densities in his .308. He used 3 reloading manuals as sources and came up with consensus loads for minimum, middle, and maximum loads then I supervised the reloading. The second year he compared the differences of the various load densities between the .308 and .30-06 to see if the case size makes much difference in the percent of velocity spread between the min-mid-max loads. This year he was inspired by a sniper special talking about the Canadian sniper that made the then longest recorded shot in Afghanistan. The program was talking about the sniper and his spotter laying the rounds out in the sun to heat them up for more velocity since it was significantly cold at the time and he was shooting at such a great distance. He decided to use .308, .30-06, .22 LR, and .38 Special rounds. The three approximate temperatures used were, -10*F (as low as freezer would go), room temp 72*F, and heated in a dehydrator to 125*F. They were all "soaked" at the given temperature for 12+ hours. When fired there was not a significant variation in the resulting velocities. Eliminated my concern about needing magnum primers for my CO elk loads compared to my typical MS white tail loads.

Being able to even do these experiments is a study in the differences between private and public school. Heard of a pellet gun experiment that was forbidden at a public school because it was a "firearm".

I purchased the shooting beta

I purchased the shooting beta chronograph from cabela's. It has worked great for me so far with bow, pistol, and rifle

I have the Beta Chrony and it

I have the Beta Chrony and it works great as I do not use it very often for my guns I use it a bunch for my bow.

I think I'll be looking into

I think I'll be looking into the beta chrony then. Thanks for the suggestions.
