Slugged the barrel when I got home from work.
The wife helped by holding the revolver while I drove the slug thru. Conversation afterwards went like this.
Wife- why are we doing this?
Me- to see what the barrel measures.
Her- why are we doing this now?
Me- because Rick asked?
Her- Oh for fu... sake.

Rick- the slug measures right at .430

Seems to me that a .4305 bullet should be just about perfect

No thread choke. This revolver was firelapped years and years ago. Probably 20 years ago.

Boy if it was anything like my first SRH that was some tough fire lapping. Oh so smooth now.

I used probably 50 rounds of 240 grit and probably that many more of 320. It shoots much better now and unless I do something stupid it just won't lead.
That Ruger stainless is tough stuff.

Yes sir! I had an LBT kit. I think Verals compound was a finer grit than the BT kit using 320 grit Clover. Took 200 rounds on mine. This was in the 90's. Before Veral's troubles. That man helped me out over the phone several times. His where my first custom molds.

That's good news, seems we are down to two causes for poor groups. Load too hot & shooter. :D

Loaded 50 rounds. 30 in 445 cases, 20 in 44 mag cases. The 445 cases are a hair too long. The loaded rounds are too long when loaded to the crimp groove. That will be dealt with once the cases are emptied.

445 cases are at 20.5, 21, 21.5 gr of H110
44 mag cases are at 20.5 and 21 gr of H110

Primers and bullets are identical to previous loads.
I would love to recover a few bullets from each load but don't have a realistic way to know the load that fired the recovered bullet.

A lot of trips downrange, only look in the fresh impact crater and don't shoot at the same target stand ya used last time.

I thought you were gonna finish trimming those cases? How ya gonna shoot them if they are too long?

Good ideas but some do epends on how many others show up to shoot. I hope it is a Brad only range time but I don't have control over that.

Cases have bullets seated deepe and crimp is into side of nose. Light crimp, just enough to remove flare from case mouth and turn it in. I'm not a fan of heavy crimps in most situations.

Oh, Rick? The LabRadar makes this all so easy. I find it simple to sight on targets downrange at 100 yards. I haven't had any issues with it detecting a bullet at all.
The USB power supply will keep that chrony running for hours and hours. Not sure why anyone would use batteries when the USB power supply is that inexpensive and so effective. I have probably 4-5 hours on mine and it shows no power drain so far.

Hhmmm . . . I suggest loading 5 and shooting 4 then measure the cartridge length to see if the bullet moved.

Have two of the power supplies for the LabRadar. Only ever used batteries in it the first time out with it.

If these move much I will know- the gun will be tied up. There is a fair amount of neck tension here, cases are expanded just enough to seat bullets without shaving.

Need to get some target center squares cut. Having a large black bull isn't the best so I add a 2" white square in the center as an aim point.

Good shooting to you Brad! I've got some testing to do also if it's not to muddy.

Our mud is starting to dry out. More shooting helps as it turns dirt over to expose new stuff to the sun.
Way too wet still for good berm mining. That comes in a few more weeks when the heat comes and dries things out. I hope to get another 5-600 pounds of range scrap this year.

a 2/6 alloy would help but it isn't quite balanced.
I think 2/4 or even 4/6 would be stronger in this instance.

the only thing I am thinking about the stronger lube is it would show what Ian is thinking about the cylinder gap better.
it would fight that happening, and fight the compression better.

The lube is a modified BR. I added an extra 6 ounces or so of wax, equal parts beeswax and microwax.
I will try to recover a bullet and see how lower pressure changes the impact on the bullet.

New alloy can be mixed this weekend. Not sure what I will try but easy enough to make something. I could even make a little Lyman 2 to try.
