5.0gr of N340 with the GM 180gr TC. I didn't get a chance to run any over the chrono today maybe monday.

With the 158gr RNFP and others I tried Unique,Bullseye,N340 and Trailboss all with the same results - 1200fps and over perfectly acceptable accuracy at 50 yards but anything in the subsonic range was a disaster.....until today! :)

I've got a very good load using 158gr XTP HP with H4227 running at 1650fps but it's LOUD out of the short barrel, I was just keen to have something quieter and cheaper for plinking.

They seem to be strange beasts with individual tastes!

Yes they can be a bit of a challenge.

Well its time to go shoot the darn thing.
First impressions I like trail boss its a interesting powder to use does it shoot any better ?.
Bullseye I am disturbed at how bad the grouping is.

One fatal mistake when load testing I normally load fifteen of each bullet weight and powder charge and then I shoot three shot strings. So five groups of three shots. This time I loaded fifty rounds of each a total waste of time it was obvious after the first five rounds things were not going well.
One of the major factors I discovered very quickly shooting the under lever with iron sights is my failing eye sight. I suspect this is the major contributor to my poor groupings. Unfortunately old age has caught up with me.
I don't see me being able to compete at any level at my age with the younger guys unless I scope the rifle ad I am not about to do that.
I will keep trying but at 66 years old I fear all the hand loading in the world is not going to help me find that V bull.

As an aside the best bullet was the Lee bullet mold it dropped at I think .360 I did not size it. I tumble lubed it and seated it at .360 it was a tight fit in the chamber but worked Ok with 3.1 grains of trail boss. I will post the target when I get round to it.
I shot it of a bench unsupported.

Hmm whats next teanews

Actually I know whats next it involves M14x1.25 taps and dies and probably a load of grief but that's the nature of the beast.
I also need to learn very quickly how to Tig weld so I can charge the client stupid amounts of money for a couple of hours work.

What about putting a peep sight on it? (If you don't already have one.) Looking through a small aperture might just sharpen things up again. I love shooting the Marlin with a peep sight. They're pretty accurate too and don't spoil the lines.....

3.1gns of Trail Boss? I reckon you would have been lucky to have got your velocity above 700fps. A tight fit may even have had the bullet begin to slow down whilst it was still in a rifle barrel! Try four grains. Still below the maximum in .38spl guise but with a velocity that should still be useful. Even at 25yds, you still need a little poke.
In 1978 I was told by my grand dad that the secret to rifle accuracy is, a quality bullet, fired down a quality barrel..... How has that changed?

Guns dont kill people. Dads with pretty Daughters do...!
