Because YOU asked!!!!!!!!!! Well, kinda! .358 WSSM

I just put it away:rolleyes:

Yes, I can take a pic. What background? White paper ok?

DON'T YOU HAVE ANYTHING MOUVE?

Really, I don't care! :)

Thanks again, in advance!

(Did you turn all of the labels back around to the front and line all your containers up again? Mr. OCD! hahahahaha)
 
H322 Picture just for Skip!

Hope this is OK. I am going to go eat dinner.

Just remember USPS Flat Rate Boxes.:D Click and ship.

Too late for dinner now! Dinner is served north of the Mason-Dixon about noon! What you are eating is SUPPER! ;)

What was I supposed to be putting in those boxes again?
(Hopefully this weekend!)
 
That's good that someone had it, because I only have H335 and AA 2230 in fast burning rifle powder. I do have SR 4759 and AA 5744, but I don't think you'll get the velocity you want out of those two.

I love H335. Measures out like a dream.

Down with stick powders!!! :p

No, but I started to turn each little particle of powder on end so you could see if they were all uniform in length and width.;)


:D
 
Okay, had some issues. Let me share!


Went to the "pusher" and he was out of the 225gr Accubond bullet. Now, that bullet has a BC of .421. If I can get it to turn over enough to stabilize in this 1:14" twist, it is going to be one long range firearm!

I think I am really close to getting that done but am pushing the envelope with pressure. No primer signs or extraction issues but it takes a bit more pressure on the trigger guard to get this baby to open. I guess by some standards I am still good to go because I don't have to beat it on the edge of the table to get it done! :)

Above the 2500fps mark with those bullets and shot a 1" group then ran out of them.

One thing I did too though, I took the inexpensive scope off and put on a nice Leupold. Made a big difference.

At any rate, because we live in Indiana and the weather is subject to change in 5 minutes to the exact opposite as to what it is now, I didn't run anything across the chronograph today. When we went to the range it was literally thunder storming and sleeting at the same time! So, we just shot and didn't think the sun was gonna ever come out so we could run some across it.

Cases in the tumbler now though and I am going to load up some more for use the early part of next week.

My groups came down to under 1" @ 100 yards, just.

I did take Paul's advice and got some IMR3031. The loads with that powder were consistently hitting 4" higher than the other powders I tested. It is because they are going faster. I did switch to a lighter bullet. My tests are now with the Hornady 200gr Interlock.

Will post pictures later!
 
A full case of IMR3031:

Best group of 200gr Hornady Interlock SP bullets.

I changed the scopes as previously mentioned and shot my last 4 Nosler 225gr. These were in the 2400fps range though and not up to the 2500fps I was shooting for with this bullet. Now, I have to wait until the pusher gets more! haha
Here is the best group with those. The first shot to the left was the first shot after a scope adjustment, the other three in the right most hole are all done without changing anything.

Seems I remember reading about a guy up your way making/selling ARs in that caliber - dtech or something like that. He might have additional load data if you can track him down.
 
They aren't being punched out for another round of reloading???

Joking...

They look like they still have rounded edges, firing pin marks look even, I'm not thinking the eye may see what needs to be seen. Maybe use a tool like a pic inside and see for case stretch tears at the bottom. I know RCBS makes that setup that has it built in but not sure if it is sold as a stand alone part. That's a compressed load of 3031, right? I'm assuming the bullet is seated deeper than that.
 
I give up. What's wrong, I can not tell from the pictures. It must be the angle or optical illusion , they look punched out as Bob said??
 
No, they aren't punched out at all. I was wondering more about the edges and such. The point is that they look pretty normal. No signs of over-pressure or anything. All of which seems to be a good thing!
 
Skip, those primers look about like the 7mm Mag I shot today, with no pressure signs visible. However, I'm using almost 6 gr more powder than the max load listed now. We've been using this same load (same brass too!) for 40 years, always with great results, but I'm trying to illustrate overloads don't always show warning signs.
 
Certainly friend you aren't saying you load 6gr more than the published load and that it is an overload and you continue to use it, are you?

I couldn't get 6gr more of anything other than Titegroup in this case anyway! ;)

Since there is not data available for this cartridge, I have to rely on the art of primer reading and case extraction. Remember, there is NO WAY, using the slow rifle powders I am, that there could be a problem with such an overload that the gun will blow up. Usually, the burst pressure of a firearm is double a standard charge.

I am going to call MGM and talk to one of their technical guys today, hopefully.
 
Yep, that's what I'm saying, but the intent was just a friendly warning for your travels in uncharted waters.

BTW, #1 son uses the same load I'm using (that my dad used before us) in a much newer M700. My M700 is my dad's, bought new in 1964.
