Hey BERGEON,

thanks for your reply.

 

Holy cow, 2840 t0 2850 with a 147gr. bullet, that´s a lot in a 24" barrel!

Did you test the RS70 with 140gr. bullets too?

As the Hornady´s prices seem to be exploded, I´m tending towards the 139 Lapua (45ct. against 30ct.). So I´m just wondering, if the RS 70 would give more speed to the "lighter" bullets too.

According to QL, the N560 and the N160 are a bit to progressive, the N550 is at max. P with 97% loaded volume.

So on paper, regarding velocity and loaded volume, RS 70 or N550 are close.   

 

 

Yes Jay the RS 70 give more velocity with less presure in big loaded volume , I I'm looking for an efficient reload for Long Range so : heavy bullet and high velocity... I prefeer the  147 gr Hornady  for a better BC than the LAPUA scenar 139 gr !

No I dont test this 139 gr with RS70...

But in an another caliber the "lighter" bullet and RS70 work very well too , for example in .243 WIN !

So why no  use the RS70 with the less expensive  6.5 mm 139 gr LAPUA Scenar  ??? 

(For SMLE : I respect your choise with the EXELENT Lapua scenar 139 gr but for me in à Long Range shooting use , the  New Hornady 153 gr A-TIP MATCH will be a good  issue too…)https://www.hornady.com/bullets/rifle/6.5mm-264-153-gr-a-tip-match#!/

I´m on the almost same route.

Working with a Tikka T3x CTR 24" barrel, the 139gr. Lapua Scenar and the 147gr. Hornady ELD-Match gave me the best groups until now.

I´ve had the N150 on hands, going up to the RS 60 and am now testing around with the RS 62.

On the high end QL would give me more velocity with the RS 70, even with the 139gr. bullet, but just almost burn all of the powder (99% at max. P).

VV seems to be a bit out of the race, because none of their powders seems to fill the gap. Again playing around with QL, regarding case volume, burnt powder rate and velocity, N550 seems to be the best option. N160 and 165 are to bulky and N560 is to slow on the books.

So RS 70 is worth a try?

Did anyone test the N550, too?

 

Cheers,

Jay 

 

 

Hi Jay,

Happy to read you, yes I tested the HORNADY 147 gr ELD MATCH (OAL = 2.90''!) in my RPR 6.5CM (24'' 5R Barrel) 

My magic load with RS 70 give me a good velocity = 2 841 mps with a very good acuracy, with LAPUA Case SRP +CCI 450 ( Picture, 8 Shots at 100 m )

My test with N560 give me a minor accuracy … 

About the 139 gr LAPUA the best powder between RS 60 and RS 62 the acuracy is better with the single base RS 62 (norma case LR)

Hi Randy,

Yes I use the moly dry with the Lyman 's ceramic kit, and any polysh media, just a long time work ! And after 3h00-4h00, I roll the bullets in a cloth to wipe the exess of moly...

Look at the results : (Hornady 147 gr ELD-Match)

Hello Randy, 

I use this  LYMAN Moly Kit,  with long time working ans poor moly ajout (about 3h00 or 4h00) anything else !

Hi Guys, here my new Long Range reload ! HORNADY 147 gr ELD- MATCH + 46.7 gr RS70 + LAPUA Case + CCI 450 OAL = 2.903'' V0 = 2841 fps (Target@ 400 m, with no wind flag, RPR 6.5CM)

For the 6.5X47L, it's a bolt bushing job or a replacement calibre barrel, or a rechamber to 260 Rem. I spoke to a gunsmith recently who said that from never doing a bolt bushing / firing pin reprofile job, he has done over 20 in the last year or two, (at somewhat over £300 a time) every one through people specifying 6.5X47L barrels on a model that was traditionally offered and used in 308 only.

 

Hello Laurie, 

Yes à  bolt with excessive space between the firing pin and firing pin hole on the bolt face will allow the primer to flow into that space...and the crater primer comes!

In my RPR I measured my clearance between my firing pin and my pin hole (measured on a crater primer) 

I have 0.05 mm (.001968'') at clearance ! Is it to much ?

Or is a right speace between between my firing pin and my pin hole?

Enjoy to read you, Laurie!

Yes, I'd agree with that.  Cup thickness isn't enough for the pressures.

The CCI 450 are the same Cup  thickness than the CCI 400, but the 450 work right with the high pressure! The metal cup is  harder ???

In my RPR, with slow powder(RS70, 47.1 gr) and heavy bullet (147 gr ELD-M) in 6.5Creedmoor LAPUA Case I use CCI 450 look at this cratered primer :

Do you think I'm in over pressure with this load ?

Thanks for the heads up Laurent.  What was the velocity at your accuracy node out of interest and your barrel length?  I'm finding a good accuracy node between 2630 and 2650fps with a 24 inch barrel.

Hello ,

I doen't measure yet my velocity to the 46.7 gr RS +147gr Hornady ELD-Match , I prefer test it for the best accuracy at 300 m 

But I hope a good vellocyty for a LR use...

I look QL for this RS70's load  :

47.1gr de RS 70 et une OAL de 74,25 mm Presure : 3898 bar - V0 = 854 m/s ( 2802 fps)

I 'll share my velocity measure if you are interesting by this LR load...

I've a 1000 to get through myself before I switch to probably CCI450's.  The standard KVBs will be disposed of.  I wouldn't want anyone else experiencing those damaging their firearms, so they're scrap.

Hi Guy ,

Yes the CCI 450 work very Right for the 6.5 Creedmoor SR Case !!!

(More than the CCIBR4)  whith Lapua Case for a long Range Load , I think I found my magic load with the RS 70...

But carrefuly for the cratered cup with this  Magnum primer !

Laurent,

certainly an improvement with the different seating depth.

I realised the figures on your loading box which I took to be velocity were seating depths,, so it would interesting to find out what speed you were getting with N560.

Richard

Hello Richard,

Happy to read You! 

I don't measure yet my velocity with my 2 slow powder (RS70 and N560) but I work with a friend called Quick Load...

Look at the results with 147 gr - COAL 2.903'' (Presure -Velocity)       

Presure Max 6.5 Creedmoor = 4350 Bar

 47.1gr de RS 70 et une OAL de 74,25 mm Presure : 3898 bar - V0 estimée à 854 m/s ( 2802 fps)

 47.2gr de N560 et une OAL de 74,25 mm Presure : 3833 bar -V0 estimée à 853 m/s (2799 fps) … (My good accuracy load with N560!)

I tell you when Iwill measur my velocity Richard !

Laurent,

 

If you mean the dotted line is the X ring, then the group is around 3.5", which would be unacceptable to me at 300m. Maybe you could try different seating depths in 5 thou increments starting at the lands or slightly into them and working back and see what that does to the groups. I would have said that N560 would be far too slow for the 6.5 Creedmoor but you seem to be getting pretty impressive speeds with the 147 grain bullet. I've been using N550 and N160 with Berger 140 VLD's and best accuracy was around 2900fps with both powders, although I'm not happy with the consistency so have also ordered some Hornady 147 ELD to try.

 

Richard.

Hello Richard,

Yes ou are in the right!   The jump in my RPR work better again with my 147 gr ELD-Match -  COAL =2.903'' (In single shot )

Here the result with the 147 gr + 47.2 gr  N560 (my best load, but I dont know yet my velocity!!! :

(yes the doting line is the X = 50 mm/1.97'')

(the nine shoot ia annonced with a bad sigth in the target ...

Now I will test the RS70 +147 gr with a slow powder  (equivalent N165) ... With 46.3 gr the density load is over- max! (with an Vibrating load with electric toothbrush )

What do you thinck about this N560 for the 6.5Creedmoor with eavier bullet?

Here my new components for load test!

Laurent

Hello

I always think (perhaps is not true !) to Long Range Shooting the better results can made with an Heavier bullet (High BC) run with a high velocity for this we necessary to use a slow powder to produce high velocity without max presure.

Well for my 6.5 Creedmoor for a LR load, I look about the HORNADY 147 gr ELD-Match (#26333)…In my RPR's barrel 1:8"

After lookin those tow link :

https://press.hornady.com/assets/site/hornady/files/load-data/6-5-creedmoor-147gr-data.pdf

http://www.wwpowder.com/PDF/Burn%20Rates%20-%202015-2016.pdf

I think I’ll choose the N560 to run this 147 gr!

Is it a good idea , can I have your opinion about my nexts choices and tests ?

A+

Laurent.

PS : Where I find this Hornady 147 gr ELD-Match in UK?

Well, i have the gun now! Rs62, 139 scenars Lapua palma brass and magnum primers! Now i need to start making some loads and get hold of a chrono!

 

Will update over the coming months!

Hi pow1,

I very interesting about your tests with RS62-139 gr Scenar using LAPUA Brass (SR) with velocity!

Because I tested this same components exept the brass, I used Norma Brass (LR) ...

I ask me if the load will be higther or less with using LR or SR for a same velocity???

Cienfuegos....no es probable que va a obtener una contesta a preguntas escribido en espanol. Puede traducirlos a ingles?

Cienfuegos you can use this tatuctor : https://www.bing.com/translator/

I understand (and QuickLoad verifies this) that RS62 gives higher MVs but I've yet too test it.

In my diferent test powder, it's the RS60 give me the Higher velocity!

Laurent.

Hobbit, I run my CM with H4350 and SMK 142 grain bullets at ~2850/60 fps and 139 Scenars at ~2900 fps. Accuracy is excellent in both cases. I know some like to push theirs faster but the elevation and wind compensation isn't worth it IMHO.

I understand (and QuickLoad verifies this) that RS62 gives higher MVs but I've yet too test it.

Hi Brillo,

It's a pleasure to read you!

It's a very good vellocity 2900 fps (884 m/s) for the association LAPUA Scenar 139gr + H4350 in 6.5Creedmoor !

Is it possible to know your load of H4350 and your lengh barrel?

Because in my RPR (24'' 5R) I run my LAPUA Scenar 139 gr Moly at 2800 fps(853 m/s) and when I see Quick Load the presure is near the Pmax with 43.85 gr H4350...Be carrefull!

Viking Arms said some months back that they would be importing Peterson Creedmoor and 308 brass as well as others.

The .308 Brass PETERSON are very good after 32 Firings!
