I have had a Oehler 35p for about 5-6 years now. I bought it before they discontinued production. They do charge more now, since they did another production run about a year ago.
I bought it after my first chrono went south.
Let me explain that I have been handloading for over 50 years, and the information I get from the Chronograph can really point out what is going on with your loads. A very useful tool. It may not be absolutely necessary, but I think it is.
I have the complete kit, (with Proof screen and printer) plus one extra screen (you never know when you may need it!). I also use a medium size, full size rifle case to carry everything as a kit.
Yesterday I chronoed 200g Montana Gold in my Kimber Grand Raptor II with 8.7 grains of AA5, to get 950fps.
My Springfield XDM .45 match did 947fps
Factory Winchester ranger, 230 grain in the Kimber went 924fps, the Springfield went 940fps
I have two Savage 12BVSS's in 22-250, 26 inch heavy barrel. I shot both of them Saturday to test out a load that I can reload for both of the rifles. The first rifle COL is 2.460, the second COL is 2.450. Sierra lists the COL at 2.350. By setting the COL to 2.430, I can load one load for both rifles. The load is 35 grains of IMR 4320, a load that I have been shooting for years in my 22-250's, with a Sierra 53 grain HPFB. All of my rifles shoot the 53 grain better than the 52 grain HPBT. Anyway the velocity in both rifles is 3532 in the first, and 3562 in the second. The COL of 2.350 shot decent, but the COL of 2.430 (which gives .020 jump in one rifle, and .032 in the other rifle) shot GREAT!. 1/2" groups (8-10 rounds), with a velocity variation of 18fps, and a SD of 0007.
Now I would know that they shot great, and with the pressures not hot (primer observance, and micing the cases), but the velocity, the consistancy are determined with the chrono. With the known velocity, I can determine and plot the trajectory. The chrono is a great tool to have.
Granted, I do not take it to the range all the time (It rains here in Western Washington), and I DO NOT let other shooters use it, but I think that it is one of the best tools that a handloader can have. I do not load my loads up to the Max. It is hard on equipment, and really does not shoot as well as a slightly reduced load.
A velocity of 3550fps is warm, and very accurate with the bullets that I use, and the barrel is much easier to clean after shooting.
Besides, I hit ground squirrels out to 300 yards, and even with a 18 power scope that can be a challenge.
The difference between men and boys is the price of their toys.
Just my two cents.
