Learn something every day. I always just considered them the same, as to what i use the measurement for and how the one is only needed. I think?

What Brett is measuring is the length from the bolt face to where every bullet design meets the start of the rifling.
I can't think how such a measurement can easily be taken though.
Normally we measure overall length to point of each bullet design simply because it's the easiest to do.

That should suit the "Anal Retentive, Compulsive Obsessive types" nicely.

That's me to a T

There's actually a "Comparator Gauge" made by Hornady for this very purpose. It comes with a number of inserts of various calibers that allow you to measure base to ogive for each type of projectile. I being the anal retentive OCD type I machine my own inserts and use a precision reamer to get them within 0.0005" of caliber. This allows me to get a precise base to ogive measurement for this particular caliber. The problem with the inserts is they are not precise to caliber and produce different measurements for each different projectile depending on profile and how far forward or back they reach the insert.
Generally you would use the gauge and measure and record the OAL for each different projectile used. That's the fastest and easiest method and one used by 99.9% of reloaders. With the precision inserts I use the measurement remains consistent irrespective of the projectile used.
Projectiles are mass produced and not what I'd call precise by any means, as a test grab 10 from a box and measure their length with a micrometer and they can vary by several thou in length and a few grains or more in mass. If seating based on COAL then you can have a variance of a few thou in Ogive to rifling which isn't ideal for precision but not an issue for hunting. These variables must and can be removed / minimised for precision distance shooting. I use a Meplat pointer to close the tip on hollow points then a custom made for me (per projectile type) Hoover Meplat trimmer to trim each projectile for consistent Meplat to Ogive length. I then measure and sort by base to Ogive / Mass. I seat each projectile 2-3 thou long then measure, set the micrometer seating die and seat the projectile.
I go to these lengths only for a couple calibers, 375Cheytac and .416 Barrett because it's a heap of work and I'd rather be out shooting.

That's very cool!

More info on the lathe too please?

"a little cannon, "
I love the boy.

I have a mate who made one when he was a just a kid. Blew a hole in dads shed.

Continued to work in the same area all his life. It was a real bang.

As it happens I spoke to him today regarding a chemical matter.

[BRNO_Bigot]

Maximum Cartridge OAL needs to be included in the load data not the firearm - it's different for each bullet design

Correct but the feedback to J.S was for Max O.A.L rather then Max C.O.A.L. (Or maybe I typo'd it in my feedback and JS owes me an uppercut)

Some background for those not familiar with OAL / COAL
Max OAL is specific to the rifle and generally a fixed number irrespective of the projectile used an its a measure of the base of the case to the Ogive of the projectile. COAL is the measurement of the base to Meplat and can be inconsistent unless projectiles are trimmed for consistent Ogive to Meplat.

Maybe the app needs a "FUDD" version, just enough functionality to record 1-2 loads per rifle

The app is more aimed at the enthusiast / collector / commercial producer who may be loading for many different rifles in the same or different chambering. I'm up near 30 chambering's I load for now so something like this app I see as having commercial value for me

I'm very late to this, but what about an OOAL - Overall Overall Length, which means "this length or anything less will fit and feed in the magazine - anything longer is not useful, no matter how many or few thousands of an inch the ogive sits from the lands.

This seems like a very useful practical measurement. I haven't read this whole thread yet, so I admit it may well be there later ....

"a muzzle brake....."

Thought, I got some time... I'll load 100ish (96 to be exact, I don't know where the other 4 cases went) worth of 44mag since I impulsively purchased some HRBC bullets and thought I'd give them a go. Plinking ammo, 19gr of AR2205 (since that's what I had). Then I thought, well, thrower is already setup for 19, I may as well do another 100'ish of SWC I cast a week ago.

Then I thought, I am doing this now anyway, I may as well use up my 7.62x54R 148gr pulled bullets I had sitting around, so in they went at 41gr give or take... After that was done, I thought, I may as well use the 303 projectiles I pulled form bad milsurp stuff I had, so in they went at 35gr of AR2208. Then my OCD kicked in, I had 20 303 cases in a batch and only 15 pulled bullets, so I added 5 Hornady 174gr FMJ BT.



Now I am thinking, screw this s**t. Thrower is fine for plinking ammo, but I was trying to get 35gr of AR2208 on the dot into 303 and thrower is just not doing it. Think I may need a Chargemaster or something And I am down to 200 LR primers and no pistol powder for my 44 plinkanator, re-stocking time (an actual reason to go into a fun shop, who knows, may walk out with a new gun)!

Better than a charge master and cheaper https://www.ebay.com.au/itm/100x0-001g- ... 4b0bd4aa50

Nah, that's still scales. Too slow. I'd like an automated powder thrower.

The one of very few chances to just slow down, turn off the rest of the world and take it easy almost meditation style and you want to rush through it .

How I feel weighing powder with a beam

Not at all, sometimes it's a job for balance beam, sometimes for my rcbs digital scales, sometimes for a powder thrower... But sometimes it's about quantity AND accuracy.

Brass for the barrel is paid for and on the way.
Thinking a .177, a .22 and a 30 cal.
All strictly ornamental of course!

Lucky it's ornamental couse axel steel would have been better if you were going to try it. Brass will look good on the mantel piece.

[on_one_wheel]

Na, plenty of brass barreled cannons around, black powder only of course though.

Here's my brass cannon

I know a bloke who owns a foundry. He has a pattern for a decent sized cannon, I've been really tempted to have one made ... for ornamental purposes l.

[on_one_wheel]

I'd love one in 12 ga

You could build a set of wheels and a trunnion for one of your 12 gauge shotguns ... string pull trigger and all

[on_one_wheel]

I really shouldn't be on t hg e net looking at this kind of stuff ... next I'll be trying to find out how to make it legit.

Alright... I thought it's a nice day today, I did everything I needed to do, I ordered a roll crimper and while I wait I thought lets get this DIY slug business on the road, first batch... And then I thought, meh, may as well use the rest of my pulled milsurp bullets, so I did that too.

Puuurty and productive.

Bentaz, as requested, 308 and 22 on the right for scale.

200something grain .32 bullet, on top of 46gr of AR2208 (nice an mild for this old girl).

Finished qty x 1100, 55gn round nose flat base, washed in Shelite to remove the lube and a quick tumble and dried in my wife's dehydrator. Spotless and very pretty.

Building the projectile is not hard but time and gear intensive. It is just like reloading, when you have a little gear you tend to add to it over time. You also build heaps of bits and pieces to make it easier and faster.

Do you sell these, Bill?
A quick tumble after being washed in shelite sounds like a terrific way to end the day!

Yep ....just don't light up in the area!

Yes, I do sell them if there is some interest. Have already sold the last batch. How many you after? I do batches of 1000. You probably do not want that many but if there are a few who want some let me know.

I usually post here first but since I've been promoted to a mod on the facebook page I owe them first dibs. I've loaded these babies to test the hearing protection of brother Bentaz's neighbours 2 towns over...heheheheh

I've saved some new materiel for the weekend and will give you first look ok That's providing I can get there cause I got some work / wife / child issues to resolve first.
