140gn mono flex in my 3030.

I picked up 50 140gn Hornady mono flex bullets in preparation of the great persecution headed our way and full of anticipation got off to a bad start!

Using CFE 223 I loaded up 5.

Later at a safe location I shot them from a very stable rest and the group was MASSIVE!

Also at 35gn it clearly was to much powder.

The primers are flatter than a witches blouse!
I've never known a Winchester 94 in 3030 shoot well ringing it's neck so I went home and dropped the charge by 2gn and cleaned the barrel with an array of chemicals in preparation for the next day.

This morning I fouled the barrel with some small game rounds and then shot the next five very very expensive bullets at 100 good paces.
Much better.

However, a couple of rounds still had flattened primers so I'll drop the charge another grain and try again, hopefully later today.
In a turn bolt rifle I wouldn't be to fussed about flattened primers but in these lever actions the ceiling is lower and so I like to still see rounded edges to the spent primer.

I retrieved a bullet, might dig the others up and take them to the scrapyard!
Anyway good deformation. But no contact in the groove!
They measure.308" exactly. I wish they made them .309"!

Hopefully I'll have something to fall back on come the great persecution!
Thanks for watching...
 
Switched to n133 and I have less pressure sign at the primer but groups are still not really good but the last five at 28gn of n133 were showing a willingness to resemble a group. IMG_20250727_173442.webp

I'm going off these bullets rapidly and this one didn't expand worth a hoot!

I am rapidly going off these bullets, they are not filling me with confidence at all!
I shall try 28.5gn to see if there is a trend.
If not the rest are souvenirs!
I'm 25 bullets in and not prepared to shoot something bigger than a rabbit with them so far!
 
Well, I think it's a flop. These bullets don't cut it. Flyer somatic.
That's the best I can do @29gn of n133

I shot three of my 130gn Speer FP and pulled the last one.17536392794332113520628333376137.webp
All shots from off a tripod at 100yds.

I will load the rest at this but have no confidence in the receiving deer if I get on one this autumn.

As of yet the future looks grim with lead free!
