So now Varget is officially "Short-Cut IMR4064"?
- Thread starter Andy
- Start date
This is news to me. Do you know if they will continue the regular IMR4064, besides the short cut. The reason I ask is that IMR4064 is a great powder for the 30-06......150 and 165 grainers. I hope the burn rate is the same, or at least, increased accuracy of loads.
I hope too that IMR4064 will continue to be produced.
The driving factor seems to be demand. Also, the makers appear to be caught up in re-inventing the wheel; 'improving' powders with new anti-copper fouling formulae, different burning rates, etc. A lot of this are calibre-specific 'niche' powders with limited application, whereas the old stand-bys were pretty universal.

I think Norma 201 and 202 are the same as rl15 and rl17. You would have to look a little more into it though.
Hmm, that's 1.4gr more varget than my manual calls for with -06 with 150s. I thought I was hot at 51.6gn.
And if you check other manuals, you will find yet other load recommendations.
In one of my Garand manuals it lists:
- 47.8 of Varget and 51.2 of IMR 4064 with 150 gr bullets!
That really surprised me, although a very accurate load in my M1 is 50 grs 4064 with 150 HPBT's.
For 168 gr:
- 45.1 Varget, 45.9 IMR 4064.
Bear in mind - these are MI Garand specific load recommendations, the M1 being powder type sensitive: i.e NO slow burning powders like 4350!

Here's what a big bunch of Hodgdon's powders are ; ADI powders. Even their load datas are directly taken from ADI.
Varget is AR2208 - check their relaoding datas

And here's the equivalence;

Yes, Sir, and been that way for a while. This from 2008...... http://www.canadiangunnutz.com/forum/showthread.php/294853-Big-variation-in-Varget-burning-rate!

I dug out an old copy (Aug/Sept 2005) issue of "Handloader" .... "IMR 4064 & Friends" by R.H. VanDenburg Jr.
"Chris Hodgden suggested that I think abut Varget as "short cut" 4064. He did NOT mean to imply any interchangeability of load data, but rather a point of reference for it's range of usefulness.
Accurate 4064 is also a "short cut powder". While it's usefulness is essentially the same IMR 4064 and Varget, it is the slowest extruded powder suitable for use in the gas operated M1 Garand in service rifle competitions.
Almost without exception with a given load, the same charge of Varget will generate higher velocity than IMR 4064 while the same charge of Accurate 4064 will generate less.
This means in terms of burning rate, from fastest to slowest, the order is Varget, IMR 4064 and Accurate 4064. The differences are modest, usually in the 20 to 70 fps range.
To make such tests requires one select a powder charge below maximum for any of them. When charges are maximized for each powder, the differences are much closer."

no no ....
equivalent are
- n203b and rl15
- URP and RL17
- MRP" and rl22
not the same just equivalent ...
