Sam,

Thank you for the kind words sir. I guarantee once you receive your 6.5x47L the rest of your rifles wont get much use. This caliber is really a pleasure to shoot and believe me, I'm not that good of a shot.. Its the rifle. The barrel is 25.125" from the breech to the muzzle. It was going to be 25" but the extra 1/8" just made it easier to set in the lathe.

I have been shooting 6.5x47L for 5 years now and im just replacing a barrel the is not worn out.
Last barrel was a standard kreiger this new one is going to be a 5R ill like some pics once i get it back.

Oh.. I see. What kind of loads are you running? I just found out today that Reloader 15 is not very temp stable. It was about 40 degrees fahrenheit here today and my groups opened up to .5's & .6's. I warmed a few rounds in my pocket and my groups shrunk back to .0's & .1's. I am thinking of switching to Varget.

Yes is is not so temp stable but i did find my most accurate load to be 123 SMK with 37.5gr of RL15.
I had good results with AR2209 (H4350) with the 123's but was a very compressed load. 130gr VLD's went well with AR2209.

I did an ocw test with 120gr NBT and AR2208 (Varget) at one stage, I dont have the target anymore but 38.5-38.8gr gave sub .5 moa groups in 10-15mph gusty wind. The info i have recorded in my reloading book for this is as follows

load- group size "- vertical "- at 100 yrds
37.0 --- --- -2941 fps
37.3gr- 1.05- 0.59
37.6gr- 1.60- 1.46
37.9gr- 0.17- 0.60
38.2gr- 1.27- 0.69 -3022 fps
38.5gr- 0.46- 0.08
38.8gr- 0.56- 0.10
39.1gr- 1.10- 0.60

A i was not allowing for wind jsut shooting round robin style to get an idea of what the laods were doing id pay more attention to the vertical component then the actucal group size. velocity for 37gr and 38.2gr reference.

I will be testing with Ar2208 when i get my rifle back as i intend to be using ADI powders only.

WARNING DO NOT ASSUME MY LOADS ARE SAFE IN YOUR RIFLE ALLWAYS START LOW AND WORK UP.

Regards Sam.

Sam,

Thanks for the data.. I did some more shooting today (35 degrees F) at 200 yards and could barely hold 1 MOA with the same charge of RL15 that produced .0 and .1 MOA at 100 yards (70 degrees F) & .2 and .3 MOA @ 300 yards (57 degrees F). I loaded 30 rounds in groups of 3 starting at 36.6 in increments of .2gr of Varget this evening. I am going to try them at 100 yards tomorrow and according to the forecast it is supposed to be in the low 40's. I hope to achieve better results in the cold weather with the Varget over the RL15.

Best regards,

Bob
 
Interesting data (and beautiful rifle btw)

This is very telling:
37.6gr- 1.60- 1.46
37.9gr- 0.17- 0.60
38.2gr- 1.27- 0.69

It shows a heck of a harmonic node at 37.9 and significantly less impressive only .3 grains in either direction. As you found, it would be difficult to repeat the tiny group with even a modest change in weather.

I have a rifle that does something similar with N133 and I'm moving on to other powders because of it.
 
I am itching to get my rifle back indeed. I now wonder why i did not do more testing with AR2208(Varget) loking at these results.
I will be testing Ar2208 with 120-123gr projectiles
and Ar2209(H4350) with 129-130gr projectiles.
just the waithing game that im not liking much.

Regads Sam.
 
Here are my results from today:

Rifle was previously zeroed at 100 yards with 123 Lapua Scenar / New Lapua brass/ 37.4gr RL-15 /CCI BR-4 primer / seated at the lands.

All groups were 3 shots each (123gr. Lapua Scenar / New Lapua brass / CCI BR-4 / Hodgdon Varget / Seated at the lands), they were fired off a bipod with a rear squeeze bag on a very unstable shooting bench at 100 yards. (I was able to see the movement of the cross hairs from my heart beat) I want to re-shoot the 38.4gr. load on a more stable shooting platform at a target with a smaller aimpoint. All in all, I am happy with the results of Varget in these conditions. RL-15 would have produced over 1 MOA groups with these meteorological conditions. The largest group measured .428" and the smallest measured .065"


12/7/2012 Range conditions at 10:00am

Temp: 34.2F
Baro: 30.17
Humid: 76.3
Alt: 1038
Wind: Calm
Precip: Freezing Rain

Looking at your results groups 6, 7, 8, all look to be hitting in the same place. I would be working on 38.0gr load as there is no POI shift with the charge weight being changed +/- .2gr

Regards Sam.
