I am NOT a reloader that said how could I go about getting reloads to try in my rifle and who can tell me if it can be done?

I would like to have a load with the Hornady 90 gr. CX bullet. I like the 120 in my 6.5 CM and wonder how the 90 gr would stack up in my 6mm ARC.

Would that bullet work in my cz527 action or would it be to long when loaded and how do I get the range info about energy and speed out at 300 yds


Thanks

Technically speaking, from what I know (and I'm not a lawyer) a "regular guy" can't make or sell you self-made ammo without a license...
That being said there could be folks who have a set up of 6Arc already, dies and trimmer etc, and might loan you the use of their equipt to be used at their place, of course you're bringing all your components with or something like that.

But a better way in your case might be to contact a company that does this sort of thing. Copper Creek does this and does "load development packs" - it's all on their website. Now they currently are all OOS of all the 6Arc stuff, but call and talk to them. Maybe they can do something if you have some 1x fired cases from your rifle, or maybe they know somebody else who does this.

The hornady data for a bolt action is the place to start for typical 24" barrel data... the 90 gmx is on their pdf of loads and the 90 Cx is probably pretty much like that but with a snazzier heat sensitive tip.

Would not be surprised if Hornady was offering your desired load relatively soon. Otherwise like mentioned above Hornady Load data is a place to start. Keep in mind, just because Hornady offers a velocity for a maximum load, your rifle may or may not like the maximum load.

Sounds like you are either looking to get in to reloading or building a good friendship with someone who does reload, perhaps extensively.

[gorillamotors]

Find a friend that reloads. Buy all the components; brass, powder, bullets, primers, and reloading dies. Ask him to load them up for you. That is legal as long as he DOES NOT charge you for the reloading services. I think California and those crazy blue states might be different.

Have you looked in to Hornady load data for 6mmARC gas & bolt gun for 80 & 90 gr GMX?

I bought the app for my phone ,it shows max load and speed but not what the energy is .

Maybe I will get the current Handloading manual to see.


Thanks

[grayfox]

those 2 pdf's used to be online, maybe they still are. they have all the info.

[CZ527 Guy]

So far, still are.

And the lower pressure gas gun data link below.

[CZ527 Guy]

Note: the difference in length of the test barrel between the gas gun data vs the bolt gun data. If all else were equal in terms of barrel length. The Gas gun lower pressure loads may not be giving up quite as much velocity as may first thought. Barrel length is a factor in velocity as well.

So with the all metal GMX or CX bullet it is lighter weight or the bullet is to long for chamber compared to like a ELD-x 

So I need a GMX with a tungsten center to have a 103gr bullet without a lead center that retains energy down range ?

I was just thinking that the cx bullets are lighter and was assuming that in order to get a 103 gr cx it would be to long for a 6arc. Is that a wrong assumption ? Tungsten is heavier than lead and harder so a cx style bullet with a tungsten core would be heavier and same length as a 103eldx.
Not knowing anything about reloading or bullets in general I assume that heavier retains energy down range better than lighter 
That would remove the lead from the bullet that would also meet California standards ?
Or have I gotten so far out in left field I am no longer in the ball park ?

[grayfox]

Bass, whoa... you need to come down to earth a bit. Speaking theoretically, yes tungsten is denser but IIRC it will be too hard for a core, won't deform like lead. Plus, it's expensive.
Why do you want a 103 lead free?
In the small-case cartridges like 6.5 grendel and 6mm Arc, you kind of need to keep within the boundaries they have to operate in. Not much excess case capacity for pushing speed. For the 6Arc if you want faster lead free, need to go lighter like the 85 gr Barnes. There are some smaller mfrs that also make good LF bullets like Maker bullets (the Trex) and cavity back bullets. Gotta go to their websites however to see what they offer, normally don't find them in any of the big-box retail or on ammoseek.
If you're not in Ca and can use lead core bullets might look at the 2 Sierras, 90 and 100 Tgk's. They have the longer sleeker secant ogive so can seat more normally in the 6Arc case.
Personally without looking in detil but my gut feeling is that a 90 CX won't give you much at 300 yds in the 6Arc.
But then again you didn't say "hunting" or "targets", so...

[CZ527 Guy]

Think I may understand where you are coming from. Yes heavier, all else being equal does better at retaining energy down range, Weight & ballistic coeficents enhances down range energy. That being said am not aware of Tungsten being employed as an alternate core or tip. Tips as I know them are composite & there size even in tungsten would not provide significant weight.

For all typical 6mm ARC applications 2.260 OAL will be the maximum cartridge length due to magazine limitations. Should you care to study the load data w various bullets, you will notice diffrent Over all lengths (OAL) bullet dependent. the point form controls max OAL due to differences in where the rifeling lands may contact the bullet. study up on throat length if you wish to better understand.

Anyhow, All copper bullets do give up weight & generally ballistic coefficient as well. So yes lead core bullets with high BC will retain more energy down range.

All copper bullets generally w most of todays designs are dependent on more velocity for proper expansion. Thus the monolithic bullets are more favored in the higher capacity cartridges. Im setting my goals for impact velocity of 2400 fps plus.

Expect at least one bullet design may perform well at lower velocity. may wish to study up on Lehigh Defense Controlled Chaos Bullets.

Thanks for your answers
As I have said I know nothing about this just asking. I did start hunting again this last year and eat deer normally 5 out of 7 days for lunch and dinner. My doctor thinks after gastric bypass surgery my diet needs protein and deer is perfect for me. That said I have noticed pieces of bone ? or bullet in some of the meat and had read about lead from the bullet. 
The shooting I have done does not go past 300 yds so using my cz527 rebarreled to 6arc I want to make sure I have the best round to make a clean kill and leave the meat clean too.
I have spent most of my life as a bass fisherman and in fishing tungsten is in use a lot to replace lead so just asking.
Hornady has the 80 and 90 gr CX but nothing larger that's why I was asking about heavier bullets and length

[grayfox]

Yes the lead cup/core bullets shed metal (mostly lead) as they enter and pass through the deer, so you might indeed be finding some of that. Much of that can be eliminated by the processing post-mortem. And a lead free would not present that issue for you.
I know some guys on here might not answer this way but have you thought about maybe a 6mm creedmoor? very controllable, still 6mm and the lead-free you can get higher velocities with the larger case size... or the 6.5 creedmoor, for that one I'm currently loading up some barnes 115 gr all coppers. Using a 20" barrel this one has your 300 yd reach with retaining enough knock down at that yardage. I'm loading for 2850 fps MV. The 115 is the newer barnes design with the lower opening threshold, but even so I don't plan on using it much below 2200. It does keep 1000 ke out to 400 yds however.
And I have some Trex 110's (BC of .420) in the 6.5, just haven't had the chance yet to try them out.
Cavity back says their design will open down to ~1500 fps. But 6.5 again, just sayin'.

Like Larry potterfield says, a guy always needs "just one more" rifle... lol!

Thanks for the reply
I have a cz557 in 6.5 CM It is what I used this year for my hunting.With the 120gr CX But back when I weighted 400lbs and had promised my grandson I would take him deer hunting I bought a cz527 in 7.62x39 because it was very light and a min for me to kill a deer (I thought). Now at 200lbs with more energy I took my grandson this year and had a great time with the 6.5 CM BUT I had this cz527 sitting in the gun safe. Thought about selling it but after seeing the 6.5 Grendel and the 6mm arc I decided to rebarrel it to 6mm ARC
The 7.62x39 was below 1000 ft/lb at about 150yds
My understanding is the 6mm ARC103gr eldx  will have 1197ft/lb at 300yds so I am good there. I bought a 24" barrel and Hornady's test info is out of a 24" barrel so I should be close with their 103gr eldx round for hunting but if I could get close to the same energy at 300 with a CX bullet that would allow me to use in California and not have lead in my food. I am happy with the 103eldx and have already bought some to break in the new barrel when I get it and will use it if I do not find something better or try my hand at reloading. 
Right now I take my grandson up to Alabama for deer and it looks like I will until I am to old to get out of the truck, but we have people in California and may hunt there too. I can always use the 6.5 CM BUT  that little cz527 keeps calling my name.

Again thanks for the reply, I saw this forum and am just now learning all I don't know

[CZ527 Guy]

Have you looked in to Hornady load data  for 6mmARC gas & bolt gun for 80 & 90 gr GMX?

I bought the app for my phone ,it shows max load and speed but not what the energy is .

Maybe I will get the current Handloading manual to see.

See if this gets you what you are looking for?

No problem and a belated welcome.
So for a 24" bolt gun, if you're using Leverevolution powder and can get what the Hornady data says, the 90 gr GMX/CX should get 3050 out of the muzzle, and be ~2424 fps/ 1174 ke at 300 yds. Their BC says 0.422 so pretty good for a lead-free. So reloading them could get you there it looks like.
I like the 103 I have a load for them in 6Arc but like them in my 6Creed better. But it's a good bullet.
For my 6Arc bolt action 22" I'm using a 100 gr Sierra tgk.
btw, I also cheat on all my rifles, I use a muzzle brake to keep the recoil down to a min, wear hearing pro even in the field.
