Can anyone suggest a max load for a 270 win using 2209 and 130g in a 26" ruger #1

The golden rule of reloading is starting low and working up to max pressure as different rifles can have different pressure limits. If I’m chasing maximum pressures, I’ll start with middle of the road listed data and work up. These days I’m happiest with middle of the road velocities with good accuracy. It’s easier on the brass , gun and shooter.If you need to load to max pressure to get the results you want I would suggest a more powerful cartridge . In this case 7mm rem mag. JMHO, I hope it’s useful to you. Be safe, cheers

I would not exceed the listed maximum for that calibre, powder and projectile regardless of rifle used based on someones comments on an internet post. Only through carefully considered experimentation in your own rifle can you creep over listed MAX, and it very seldom has any value for hunting purposes to do so. Read the post by bigrich again, he is absolutely spot-on.

Thanks fellows . I appreciate your advice.

I do seem to have a lot of air space in the cartridge that worries me. I am concerned that the powder lies flat that I am told can cause over pressure.

Looks like the username matches the loading ability besides that you get half a dozen rifles work up a maximum load for every one of them and they'll all be different so many things to take into consideration from a maximum load seating depth primer tight chamber sloppy chamber just to name a few

Fortunately I am a lot better cowboy then reloader

I just grabbed a 270 Winchester (Winchester brand) case and filled 51.0g of 2209, ADI recommended Starting Load for 130g projectiles. Case appears by eye to be +85% of volume sitting maybe 3mm below the shoulder. This seems perfect to me, I increased to 54.3g, the listed maximum in ADI 5th Edition (2010) and the load came to the start of the shoulder. If you are getting a lot of air space perhaps you should check your scales against another set or a Certified Weight, perhaps even check you do have AR2209 powder? Generally speaking too little powder leads to squib loads pushing the projectile into the barrel but not out of it, sometimes leading to people firing again in an obstructed barrel and having problems. Over pressure generally occurs from overloading, wrong powder, or too little of a much faster powder leading to double detonation events which those loading for sub-sonic often obviate by use of fillers (kapok, cotton wool etc) to keep the powder back against the primer.

mate , use ADI load data for ADI powder and you can't go wrong . seat bullets to the listed cartridge overall length as given by the bullet maker , don't get sucked into seating projectiles out like target shooters do, as that can create pressure problems and is probably left alone till you've built up experience .

make sure your scales , measuring callipers and dies are all accurate and correctly set up . preparation of cases and accurate tools are essential for accurate reloading.

do every process in steps and don't stop or get distracted especially when measuring powder and filling cases .
1- clean cases (i use a hornady case cleaner that uses the corn cob medium)
2- full length resize cases in your press with sizing die
3 clean primer pockets ,i use a rcbs tool with stainless brush bristles
4- trim cases to length if required . accurate measuring of the case is essential ,as to long a case can give pressure problems . i use a hornady case trimmer
5-deburr case mouths with the required tool . i wipe the inside of the neck with a cotton wool bud to ensure no bits of brass are left behind to stuff up bullet seating
6- fit primer in case and sit in loading tray . once all the cases you want to load are sitting in the tray primed move on to the next step
7- measuring powder . do all the cases, don't stop until their all filled, and check every case is filled . a stuck bullet in your barrel from a squib load could really ruin your day . and the rifle if you don't realize and fire the next round
8- seat bullets . i sometimes adjust my seater up high and adjust down slowly until desired cartridge length is found . recheck the depth on the next couple you seat as slowly inching down with the first case plays with neck tension a little and the next bullets may sit higher .
9- go shoot stuff

this is the process i use , i don't think i left anything out , others may have different opinions . if you not sure ask or spend the time to check it out . there are helpful experienced people on this forum who will give advice if needed . just ask , check everything twice and be safe

Wow. Thanks for the time to help. I won’t be so worried about the airspace . I am doing everything else right. I don’t need a power pack just a safe one.

yup

put the right bullet for the job, in the right place accurately . doesn't matter if it hot loaded going 200fps faster

Cowboy, you will find that perhaps choosing a different powder in a recommended load, (definitely look up the online ADI loading manual) that the airspace in the case will be different.
For example, if I'm using a midrange load in a 308, 2206H will fill the case to the bottom of the shoulder, whereas a midrange load with 2208 will be compressed.
Neither are unsafe.
And, as has been suggested, different brands of cases show different capacities in volume.
Meaning of course, they all have to have the same external dimensions, but because the wall thickness varies between brands, the volumes (using the same powder charge) looks different.
If you stay within the loading manual recommendations, this isn't a drama at all.
As you get more experienced, you will see how this makes a difference when/if you get a chronograph and get super serious into it.
If all you want is a reliable, accurate hunting load you can make up and repeat whenever you feel the need, you don't have to get into all that extra expense and time.
To most people, that's just because it keeps them busy in between going hunting and really doesn't achieve anything from a hunting perspective.
Have fun mate, it's easy.
