Any thoughts on IMR 4064 for the 1-13 twist and 155gr Sierra?
Shot a couple of rds with this load at the range today.

Should we assume that this is for a .308" diameter bullet and
I'm guessing here 308 Win???
30/06?
30/40 Krag?

What you describe is normally used for Palma match shooting, bullet, powder and twist. Shot Palma matches for several years and used Krieger 30" SS barrel 1/13 twist and SMK Palma 155's. Lapua brass, Fed. 210M primers, 46.2grs. of IMR4064 and it gave velocity of some 2950fps to reach the 1000yd. line super sonic. Good load but that little bullet is a bit on the tricky side in any wind, just takes practice with it and works fine for long range in the 308 caliber. Mind you this was in strong bolt action rifle and pressure is up there with the load but given by Sierra manual for accuracy load.

Do you prefer it to Varget for this set up?

4064 is an excellent powder. It is the only powder I am aware of that has been praised as "one of the least temperature sensitive powders" by another manufacturer (Hodgon). I believe they said that about it before they bought out the IMR line.

I like and have used IMR 4064 but for .308 I generally prefer the Ball powders: W748, H335 & Bl-C2.

OK. I'll ask. What's with the 1:13 twist. (OK I see, optimized)

I just bought some 155 before it got cold but I'm in a 1:10 twist. Haven't gotten to the range, I loaded AR-comp, Varget, 748.

When I am ordering a barrel I want the heaviest which is a .9 diameter and those seem to be mostly in 1-13 twist.

I've been using 4064 in 30-06 with 150 grain bullets for 50 yrs. For most of those 50 yrs, I kept hearing 4350 is THE powder. Tried it and 4064 works much better in my rifle.

It could be that it is a 1-12T.I noticed on an invoice I had ordered a 12T a while ago.I tried to determine twist rate this morning but my cleaning rod and rifling are not cooperating.

IMR4064 is the powder I used to work up a load for my 308Win, and though it is very accurate, I am not satisfied with it because the velocity is dismal. I plan on trying IMR 8208XBR because of higher velocities and accuracy reported by other handloaders. I have also read good things about some of the other ball powders.

I shot many kegs of 4064 up always has worked well.

I hope I get my rifle back soon from my smith as the one I have on hand is due for a new barrel. It is throwing some wicked flyers.

IMR-4064 and WW-748 are always good powders in the .308..but Varget is THE powder for the .308 IMO...

One of the real beauties of the 308 is the vast selection of excellent powders to choose from.

Here is a target of a three shot group at 100yds off the bench with open sights using the IMR 4064 load and the Sierra 155gr bullet.I shot this with my Lothar Walther barrelled rifle.This barrel is my first LW and so far it is doing good.I have got it near hot a few times and it is still printing the same three shot group in the bullseye week after week-after a good cleaning.This time I had a fouler shot shoot wide to the left-I must have left a little too much oil in the bore-other times a fouler was not needed.

Shootaway,
A Sierra 155 in a 308 the go to powder is Varget at approx. 46 grs. The majority of people I shoot NRA long range/Palma with use Varget, but one caution, there can be some lot to lot variations. The old standard 13 twist with the 155 seems to be falling out of favor, seeing more 12,11, and 10 twist's now.

Gundog 64,I don't shoot Palma.I shoot 100yds standing offhand.I chose the long heavy Palma heavy barrel because it does not get hot as easy and therefore extends the life of my barrel, also it gives me good excercise as it is difficult to hold steady.The Palma chamber lets me use less powder too-I use about 36 grains of IMR 4064.There is less recoil with the 155 compared to the heavier bullets.I have tried Varget and N140 both work well.

God Ray, I find myself agreeing with you again. 45 grains of Varget under a 180 gr SST or AMAX is a great load for me; it is my standard 500 yard gong rifle.

For many years 4064 was my go to powder for 220 Swift, 22-250, 7x57, 250 Sav, and several others using lighter bullets and was the most accurate in the Swift, 22-250, and 250 Sav Imp. When I acquired my Chrono it also proved to be the highest velocity in those and a few others.

In todays world with the proliferation of excellent bullets and powders I would go with powders like CFE223, AR COMP, Varget, 8208, 748, TAC which are primarily designed for those case volumes.

I would also listen to those that shoot Palma, they will have the latest and greatest data.


My 16" 1-14 experimental barrel DOES NOT LIKE BULLETS much over 1.00" long, especially BT's but does OK with 130-150 gr at near that length and ~2500fs and Varget is the most accurate with RL15 and 4064 very close...H380 and 748 give slightly higher velos at slightly lower pressures but are not as accurate for some reason. My standard load for this particular 308 is 130 gr Horn SP's, Varget at ~2600 fs...it relatively low energy but totally wipes out sageratz.

I use a stiff load of CFE223, Horn 165 SP's, in my "hunting" 26", 1-12 LA 308 at ~2950fs.

I agree lots of new powders out there and you named some that I like..I do like CFE 223 but only in certain calibers, as it does get the velocity they claim but Ive found it runs pressure up pretty fast towards max..I am a fan of WW-748, IMR-40-64, H414, and ww760 and then we have the wonderful RL powders, and Varget is my go to .308 load.

These new powders flo thu a measure so well that I seldom weigh more than two tosses per box of shells, sometimes less..It sure speeds things up if one knows his measure.
