45ACP Edge

[38superman]

Took my Edge to the range this weekend to chrono some ammo.

I'm still looking for the right load to race with.

I had Precision Delta 230 FMJ RN loaded with Clays, Titegroup and N320.

I had 50 rounds of each starting with loads 10% below max and working up.

It was a warm day with temperature at 83 deg.

I started with the Viht loads and discovered that the accuracy was right around 2 3/4".

Velocity was about as expected with major power factor coming at 5.0 grains.

I noticed that the extreme spread was, well.... extreme.

Ten shots with each load produced a variance from about 50 to 70 fps.

I was a little disappointed with the groups but chalked it up to eyes that aren't what they used to be and a factory trigger that is much too heavy for my taste.

I moved on to the Clays and I understand why it has many fans.

The recoil was soft, and the average group size was better, going around 2 1/2".

There were some excellent groups sprinkled in among the 10 targets.

Major power factor emerged at 3.9 grains which also produced a group under 3/4".

This might be the load I was looking for except that the cycle time with this powder seemed really long and lazy.

The gun functioned fine, but don't know if I could get used to that.

I started shooting the Titegroup loads and soon discovered they don't call it Titegroup for nothing.

The accuracy was just over 2" on average and almost every group had 3 or 4 rounds through one ragged hole.

The slide cycle was snappy but recoil was reasonably soft and quite managable.

4.5 grains produced best accuracy but barely made major.

4.6 gets it done with an acceptable margin.

All three powders seemed to burn pretty clean.

However, until something better comes along it looks like Titegroup for me.

I'm wondering how well it meters through a 650 powder measure.

Anyone want to clue me in on that?

I use 4.7 of titegroup for my 650. Of the 12 times I measured the powder charge 10 times was 4.7, the others were 4.6.
