Well just loaded up some 405 laser casts and 42 grs of RL-7 in some ww brass. Now my STBL feels like I thought a 45-70 would. Those 300gr factory Winchester factory's felt like nothing compaired to these. I was going load up fifty of them but not sure now I'd want to shoot that many.

How many rounds do have to shoot to get the barrel to lead up? Anyone have an idea of how fast these are moving. I have added the chrono yet. Going shooting now so I will load up some more. Ill let you know how they do.

Also when I crimped with the Lyman dies I had a hard time getting it to load out farther then 2.032". The book says to load out to 2.055" as I remember. I will say it loaded and ejected great.

ktmhans –

If this will be your first time shooting cast? You’ll need to remove all traces of copper fouling first, start with a clean barrel…If not, leading can be expected!!

Velocity – maybe 1400-1500fps…That will be at/or above the pressure limits of that bevel base bullet and lead some more, but will depend on the condition of your barrel.

Have fun shooting ;D

A typo on the 2.032" COL ??

Should be more like 2.5" COL ;)

The problem with using a COL of 2.32 vs one at 2.55" is there will be almost another 1/4" of bullet located inside the case - and that "will" increase pressure!

I'd be looking at getting that bullet seating issue worked out before increasing powder charge. ;)

No just about .023" I was pulling the numbers from memory before. Never a good idea. I never would have tried them back short.

So I shot 15 rnds off the 42 gr. And 3 of the 43gr. I loaded up. I don't think I have to over 42. Shoulder wasn't lovin the bench. Standing wasn't bad though. Accuracy was pretty good but hard to tell it was really the first time shooting it and I was adjusting sights, holding positions and just plain old having fun shooting it. Ill load up some more and drop it in a sled this time around.

As far as leading, I pulled the bolt out and ran the snake down it one pull and I don't see anything up the bore. No lack of sheen or dull areas. Can anyone describe what leading would look like.
I'm not sure how fast they were moving g but I think its safe to say that if I hit it right . Its goin down.
