H4350 substitute for 6.5 creedmoor

[bearcatrp]

Varget works just fine with 140s, but you'd sacrifice 50-100fps compared to H4350.

May try both and chrono them to see.

[Rob01]

At least that much velocity especially with longer barrels.

[bearcatrp]

Been using varget with 178 gr bullets with great success in my 308. Better than 4064 that I started with. Now I stock up on varget every time I see it on the shelves, which isn't to often. that powder is like gold.

Really? What was your powder weight?

[Rob01]

I use Varget with my 308 178s also. Been using it for years and it's my go to .308 powder. Depending on brass used I use between 44-45grns. Most find their higher node in the 43-45grn area. Hodgdon lists 42 as min and 45 as max with the 175/178 and Varget.

Now to primers. What do you think of cci br2 benchrest rifle primers? Will there be a difference between those and their large rifle primers?

[Rob01]

Don't use either so can't comment but in the Federal 210M vs 210 I can tell you there is no performance difference in any of the cartridges i have tested them in.

So it's most likely not going to be worth the extra 4 cents a primer? That sounds silly and neglegable, but is it?

[Rob01]

In the Federals it isn't but don't know about the CCI. Buy one of each and try them out. Load the exact same loads and shoot them over the chrono and for accuracy. That's how I tested the Feds.

Not enough to warrant the price...I shoot all of the primers mentioned and several others...the CCI200s are great primers and are my go to when starting load development. Once I find a load I will load the same charge and try different primers to see if things tighten up.

Thanks. The 200s are found locally too

Shooting the 140grn bullets the H4350 burn rate is where you want to look go get really good velocity and accuracy. IMR4350, IMR4451, RL17, etc. Some use 4831 but I think it's a little too slow to get good velocity. You can get good accuracy from other powders both slower and faster but you usually lose some velocity. The round was developed around H4350 so it is a good place to be.

What rifle you get? Also check out the 6.5 Creedmoor forum at http://www.65creedmoor.com/ Lots of good info.
Thanks for the link. Forgot about them. Savage finally released a 10T in 6.5 creedmoor at cabelas.

Really? What was your powder weight?

For the 178 gr hornady match, 43.7 gr of varget using lapua brass. For the 178 gr hornady ELD, 43.9 gr of varget using lapua brass.

I use Varget with my 308 178s also. Been using it for years and it's my go to .308 powder. Depending on brass used I use between 44-45grns. Most find their higher node in the 43-45grn area. Hodgdon lists 42 as min and 45 as max with the 175/178 and Varget.

Do you have chrono data with your 44-45 gr of powder? I thought I was pushing the higher limits with 43.9. Barrel bounces enough to lose scope site on each shot. Didn't see any pressure signs getting to 44 grains but my best groups were with 43.9 with 44.0 a close second. My ballistics app tells me it goes subsonic a little over 1000 yards.

[Rob01]

Using Hornady brass and 44grns I am getting 2730fps from a 22" barrel and 2690fps from a 20" barrel. With Winchester brass and the 45grns the numbers were similar.

Make sure you have a good solid shooting position behind the rifle to control the hop as much as possible.

Hodgdon web site shows allot of different powders to use but superformance is not one of them. Varget, xbr8208, 4166 just to name a few are on there. http://www.hodgdonreloading.com/

Hodgdon also lists much of their data in CUP, when it has been known for several decades that CUP isn't accurate when used over about 45,000psi.

Pick-up your Hornady manual, and you'll find plenty of data for Superformance in the Creedmoor. Or you can look at any of the Pressure Traces I've posted with it in the Creed.

Well I bought rounds, powder and primers. They only had the rem's I plan on using cci but this is all I could find.

The factory ammo is also just to get me to the range and to give me brass to reload.

Next pay check is going towards a hand primer and another box of ammo

Superformance looks to be ok but reloader-17 looks the best. Never used that before so will start looking for it. I looked at possibly reloading for 243 using superformance but only up to 80 gr bullets. Have a boat load of 243 ammo so don't need to reload for that any time soon. Did order some Hornady 140 gr ELD match since I can't find any around town. Got a free hand gun case for the order. Grafs has it in stock if you need some ammo.

[bearcatrp]

Just picked up some reloader-17 when I was in town. H4350 seems to be like varget, hard to get. I use varget for my 308 bolt. For those of you who have tried varget, did you have to push the limits to get good performace or just not that good of powder to use? Same with superformace, you folks pushing the limits?

To each his own, by all means, but Superformance is much more flexible if you need velocity and not pressure.
If you want to try Superformance, it is DIRT cheap from Bruno.
