Just got some 30-06 bullets, wanting to reload them, but unsure of the start and max load for a 165 grain spitzer Sierra GameKing bullet. Sorry guys I know I need to get a manual, but have not had the money or the time. Oh yea the powder type is Reloader 19. Thanks

Yea I think they are an older brand of ammo, not sure though. The box they are in looks old. The price for 100 at the time was $13.33, which makes me think they are a few years old. lol

My Sierra manual lists data for a 165 grain SBT.
Start is 50.4 grains of Reloader 19. Max is 55.8.

On page 41 of the manual, Sierra notes that the GameKing bullets are included in the SBT description. Spitzer Boat Tail.

If you can't afford a $20 reloading manual, I don't know what to tell you.

Oh wait!
I do know what to tell you.

Go to the free Hodgdon website and look at the data for the 165 grain Sierra SPBT they show for 18 Hodgdon & Alliant powders.
Did I mention it's free!

As I mentioned in my first post rcmodel, I am using RL19. That website has no information on this type of powder. Thanks for info though.

Thanks to rcmodel for leading me to another website where they do show data for RL19. For those who need it, you can find it at http://www.alliantpowder.com/reloaders/default.aspx

Well I started my loads at 50.4 grains. I believe I started just where I needed to. I was shooting from 50 yards, 5 shot group and they were all touching. I have never held that tight of group before. Absolutely amazing.

Glad you like the ammo. You might want to stretch out to at least 100 yards to check the accuracy of your ammo.

IMR 4350 is another good old '06 powder for a bolt gun.

+1 for the 4350 recommendation. Much as I like and use Allliant propellants, 4350 is my go to for .30-06. ANY of the 4350s.
I suspect, though, that R19 is in the same range and will work as well (seems it has, at least at the 50 yard line)

I agree wit using 4350 in 30-06 ammo made for bolt action rifles. I use only H4350 for my 30-06 ammo use in a bolt action rifle with either a 165gr or 168gr bullet.

I bought 165gr SGK last year. I believe they are still on the website.

Cant help with the load data though, have you checked hodgdon's website?

Well I stepped off 100 yards and tried my luck again. With a 5 shot group, all shots were touching and you could place a nickel over the holes and not see any of the edges. I am very pleased with this recipe.

Well I started my loads at 50.4 grains.
What kind of velocity is that load generating because that is a little light acording to Alliant. Alliant lists a max charge of RL-19 with a 168gr Sierra MK as 61.0gr and 59.0gr with a 165gr Speer SP bullet. When you drop back 10% for a starting load that works out to 54.9gr and 53.1gr respectively. I'm just curious how conservative Sierra is being compared to Alliant.

ArchA: Sierra lists 2500 fps as the velocity for the 165-168 over 50.4 grains of Reloader 19.
Firearm: Savage 116, 26" barrel

Pete,
Thanks for the info but I already know what Sierra is saying. I was wondering what velocity he was getting from his rifle which probably doesn't have a 26" barrel like the Sierra data was done with. Like I said, "I'm just curious how conservative Sierra is being compared to Alliant."

ArchAngelCD,

I find Alliant's load data to be much more realistic than Sierra's. I called Sierra up one time to inquire about the pressure of what they call "Max" loads. I was told that they don't know what the pressure is with their Max loads, that's just the point at which they decided to stop. So much for the science behind Sierra's load data.:rolleyes:

I also tend to trust the load data from powder manufacturers most too. (except for velocity numbers lol)

I don't think you could have picked a better powder for that particular cartridge with that bullet weight. But first things first, you need to spend the money on at least a couple fo reloading books. Pick one for your general load data, and then one for that will teach you the entire process of reloading. For data, I really like the "One cartridge" books because they have most of the powder and bullet manufacturer's data for that specific cartridge. And then a good book, that will provide good reloading instruction in easy to understand termenology is Speer. Their book has easy refrence termenology translation cross over.

RL19 is a slow burning powder for the 30-06 and is easier to do load developement with than the faster burning powders out there. But somehting to be very aware of when using this and some of the other slow burning powders is where to start, which is what you were asking.

Slow burner's will commonly act poorly, and can even produce excessive pressures if they are reduced below published minimum data. When I do a load developement with these powders I always start around the mid range of the data. However, I realize many bullet and powder manfacturer's will have conflicting data, but as long as you abide by one of the two sources you'll be OK. On that note, Sierra usually has some pretty hot data in my experience.

Another trait of these type powders is pressures and velocities will commonly drop slightly when approaching the higher end of the data, often this is when the charge becomes compressed. This has also been the point in which my velocities and accuracy are most consistent. But all actions are different and will produce variations in both pressures and velocities compared to another action of the same exact model and cartridge, so working up is absolutely necessary, don't just start at the maximum charge. Some where in the middle will be fine.

Use only the type of primer listed in the data. I'm not refering to the brand so muc, but rather magnum or standard. Now brands of primers can effect performance in multiple ways, one of which is pressures.

There is just so much more to cover, which is why it is so important to get yourself a really good instructional manual. And in addition to that, high powered rifle is more involved than loading pistol cartridges. Keeping brass trimmed to spec. is extremely important with bottle neck cartridges, and once again because pressures are greatly influenced by brass length.
