CM 84E ammunition

I'm about to buy a Morini CM84E, any comments on which is the "best" ammunition to use ? i.e. does it "like" (generally speaking) one brand or another ?
Also, does everyone use the same ammunition in training as in matches ?

All comments gratefully received.

Trev.

Trevor:

You'll find if you do a search that this has been cussed and discussed several times before.

Shorthand version:

- Buy match grade ammo (some cheap stuff like CCI standard vel (blue box) Aguila, Wolf, etc. are considered "Match Ammo" OBTW)
- Each gun will slightly prefer one lot number (not brand) over another; two guns with consecutive serial numbers will slighlty prefer different brands/lot numbers

More importantly

- The difference between lot numbers for a single brand are frequently larger than the differences between different brands, for an individual gun
- The differences between serial numbers of individual gun models will frequently be larger than the differences between types of gun, for an individual lot number of ammo

Most importantly

- The differences between several "really good" lot number/serial number combinations and the "best" combination are meaningless

Therefore

- Find something that works "pretty good"* and forget about it until you are regularly breaking 550 in FP

These "rules of thumb" apply to .22 LR only- and are particularly true for pistols; still pretty true for rifles.

In my humble (of course) opinion.

* something that will give you 98%, ten shot groups, with dot scope, off sandbags

Mine works fine with Eley ammo. Actually the cheap yellow Standard Pistol cartrigde works very well. I shot 565 with it.

Steve,

How did you mount a Dot scope on your FP? What hardware did you select? Thanks in advance for your help..

Jim:

Get a block of nylon/phenolic/hardwood and drill a hole through it slightly undersize to barrel OD. Split in half and mount brakets ("Dogears") so you can clamp the two pieces together around the barrel. Saw a piece off a weaver rail to mount the dot on and screw it intot he top of the block.

I use a single-mount on a 1" Ultra Dot . . . with only one mount it "vibrates" a bit between shots but I can also keep the length of the mount block shorter.

I clamp it on my CM84E just in front of the reciever. I know it's having some effects on barrel harmonics etc. but I am looking for relative performance between different rounds, not absolute performance (since I shoot offhand anyhow).

Steve

[I tried clamping a laser sight onto the trigger guard . . . great idea in theory but in practice I would have had to aim the while looking at the dot on the target through a scope. Also limited the use of sandbags. Just wasn't practical.]

And always remember Ragnar Skanaker, who, when asked about his choice of ammo, replied "the cheapest, of course!"

Thank you, it was one of those days when everything seemed to work out just the way you want to.

Tycho:
When was this? Last time I spoke with mr Skanaker he used Norma 1 and 2. They are not very cheap at all, but he is sponsored by Norma.
However I don't think he would go to the WC or Olympics with let's say CCI crap-ammo just becuase it's cheap.

It was in an interview some years ago, but I can't remember where, perhaps I'll find it somewhere someday while cleaning up. I am very sure though about what (was written that) he said - I laughed for days afterwards :-) Me, as a FP-only-for-recreation shooter - I prefer the sort of ammo which cases get ejected by my 84E every single time - I hate those sticky cases...

Ammo & Ragnar

Our club in Melbourne (Oz) has a photo of Ragnar, next to a target with a possible (100) in Free Pistol - shot at the club years ago.
He used T22 because at the time it was the cheapest.
Backs up the claim...

By the way I use Geco Rifle in my Cm84e. Groups are only 3-4mm larger than Midas L(shot from a clamped
vice), which costs 5 times the price!
