What did you do in the reloading room recently?

Loaded some 10mm with a 180 grain coated lead bullet and Longshot. I've never used Longshot before. This gun throws empties so far, I can't find them all but I don't care. These are all small primer cases which I hate. Both primer sizes in 45acp is bad enough. Now 10mm too? What a pain in the ass.
Longshot is a great powder. It has a reputation for being much louder than other powders. Competitive shooters often refer to it as Loudshot. It works great in an open class auto with very light bullets. The most important thing to know about Longshot is that it will without question destroy anything made out of plastic if left exposed for an extended time. This includes your powder hopper, shotgun shells and wads.
 
As Andrew said it’s mostly about bullet profile.
I always keep this picture handy so you can see the difference in pressure with deep seating.

If you have a 124 jacketed and 124 cast lead that now has a lube groove added in it ends up being a lot longer. Enough to make a difference depending on the load.

Also some of the slow powders like H110 get a little weird when they’re not loaded just right.
If you’re running a light cast bullet that has way less friction that jacketed and you’re running on the low end of the data then maybe that reduced friction and weight as just enough to effectively be one of those H110 light loads that gets kind of hairy.
That’s more of the exception not the rule. Most times people aren’t trying to push H110 max loads with cast bullets.

This - If you go through a number of loads for similar bullet weights with different profiles, you will find that if you seat the bullet to the same depth in the case to reach similar effective case volumes then the loads will have similar pressures and velocities.
 
Snuck away for a bit and was able to load up some test rounds for a new cartridge!

26” Bartlein 1-8” 7 SAUM
ADG Brass
171gr Match Burners
H4831sc

Loaded in half gr increments across 2.5 grains just looking for some baseline numbers. Once I have a safe charge to work with will load up 200 to get this bad boy sped up and form brass.

I’m also still proofing out the BRA load. I loaded up 10 each at 30.4, 30.6, 30.8 to see how they compare to last charge weight test. By the looks of it this barrel might like to run a little faster than the last. 30.6 is running 2850. View attachment 747709

Hoping to run these in the morning before it gets too nasty.
What do you mean "sped up"?

People started telling me barrels speed up, I didn't notice a damn change in mine after 260 rounds, and I used a chrono for all 260.

Then Erik Cortina released a series of short videos (you can find them on YouTube) and he didn't notice a difference.

I read some articles, did not look for cartridge specific, and people didn't find a difference. Seems like shooting rounds to speed up the barrel is a waste of reloading components.

Maybe I read about the wrong cartridges?

I am curious as to people's personal experience. Maybe it happens with certain calibers or barrel manufacturers.

Made another 100 rounds 45acp when I got home from work.

200 grain lswc
5 grains titegpup

Keeping the dies and powder drop set up for this load and going to try to do 100 a nigh for awhile to build up some stock for plate shoots.

Pulled the turret off and cleaned and lubricated the plate when I was done. The turret was getting a little "gritty".

it’s my favorite time in the loading room when you have a “ go to” load set up and can leave it for a while.

I take a perverse pleasure each August of setting up the MEC loaders on the bench and cranking out 500 each of trap (12 gauge) and skeet (20 gauge) loads. Just enough to get limbered up for ducks. I haven’t changed my set up on those since I bought them in early 80’s.

It's nice to sit down.....pour some powder in the measure.....check a charge on the scale and start cranking.

My 6 dasher did speed up at around may be 3rd hundred shots. The groupings and SD did not change, only speed increased.

On 6.5cm bergara I think there was some change too, but less pronounced.

That “go to load set up”. Couldn’t agree with you more.

I shoot a lot of 124grn 9mm. One of my 650’s is left set up always for that load. The other is set up for whatever else i feel like loading at the time.

I have a major match tomorrow. I’ll load another 200 rounds as cushion for it after work today. Won’t take long.

forgot about this, but, here is a data sample - as i keep all the sessions:
earliest 06/09/22 - 31gr - 2836
1683300469241.png

current state of affairs - 30.7gr varget - 2908fps - es/sd 16/5, as of 12/8/22

1683300589539.png

PS. it looks like i did 5 shots of 31.1gr load in same session as well and it shows 2944fps, with a very impressive ES/SD 4/2 - but i did not seem to keep a picture of that group somehow, so, i guess it did not do that good. plus i know that anything above 30.9gr damages that brass in my gun in 2-3 firings, so, would not use it anyway.

I think every barrel is different. My last BRA barrel I had a pretty significant speed up. I ended up dropping .6gr to maintain the same speed.

The current barrel I’m 325 rounds in and I’ve not seen a drastic increase in speed.

IMO it’s really not a waste of components because i still have to form my brass anyways and I use this time to practice.

I’ve still got roughly 200 rounds loaded up to form for the BRA. I’ll go to Range with 15-20 development loads and than the forming loads I go shoot positional.
 
Started a batch if 44 mag with

240 grain cast swc
Titegroup at 9.6

I don't know how people say that reloading doest save money.......below is the cost of the above load even at 9 bucks a pack for primers

$15.46 a box. Pretty good savings I'd say.

Titegroup with a cast 240 is a solid economic load.

Cast your own boolits and increase your savings! 🤣🤣🤣
 
Must be a 10mm/1911 thing here, I have a Kimber, Ruger, and RIA and they all launch the brass way back and to my right. Been using 9.6gr of Blue Dot under a 180gr head.
I run about the same Blue Dot load or a similar one with Power Pistol in my Delta Elite. It sends brass over the pistol range side barrier and I have to go into the rifle range to get it LOL.
 
Heads up I posted the 2023 bullet casting seminar thread. Don’t be like @DW357
Be a cool kid and learn to cast!!
