powder for 70 nosler ballistic tips in 243?

This evening I tried some varget for pushing 70 grain nosler ballistic tips, lit with federal 210 gm match primers. 40.0 to 42.0 grains in 0.5 grain increments in my 243 this evening... 0.030 off the lands

results were entirely unacceptable...

what have you folks found to work with the 70 grain nolsers?

I am starting to wonder if my new barrel is a piece of junk.... it does not like hornady 87 grain v-maxes either,

Interesting results. I'm new to the .243 but tried the 70 gr with IMR4350 only because I have a lot of it. The results were very good for accuracy and over the crony.

I felt that Varget was a little to fast and didn't try it.
 
I use to run 70g noslers with IMR 4350 behind them with very good results. And I run .010 off the lands also. Give it a try...Jason
 
In my factory barrel I ran 39gr. of IMR 4064 or 40gr. of Varget with the 70NBT, Lapua brass, and CCI LRM primers. They averaged 3460fps and 3450fps respectively. The 4064 seemed to group better in the summer months and the Varget didn't group as well, but was more consistent through the year. It was my groundhog load and rarely exited chucks, even at close distances. I seated just off the lands after having a few bullets pulled loose and filling my action with powder

While I have only used this powder for a short time early results have been favorable. The new Alliant powder MR4000 with 87gr Vmax and the 88gr Berger has been a good performer. Velocity is 3370fps range and groups have been sub MOA. I do have some 70gr Nosler loaded but IIRC I used IMR4320 but groups were good again not much long term experience as I have only had the gun a short time.
 
My savage likes benchmark with 70gr nbt and imr 4895 had decent groups also
Imr was .78 rem. Brass win.primers

Benchmark .49 all were touching with win. Brass and primers
all were shot at 100yards

I had OK group's with 65gr vmax and varget. I'll look thru my notes and see what else I tried with varget.
 
I see several suggestions to try a slower powder with the 70's

I have some imr 4320, and 4007ssc I can try

Anyone using those with success?

I started with Varget and the 70NBT's, went through 2 or 3 other powders then, before moving on to a variety of different bullets and powder combo's - but nothing just quite satisfied my quest for extreme accuracy. Then I got onto Reloder 19 and with some good advice from the folks at Alliant - WOW! It came together for me. I used CCI BR2 primers, and gave them plenty of jump (2.620", where my one buddy's 243 came together at 2.625" and a few tenths below my load giving the same exact velocity). But this is the best combination I have found. The 85HPBT's are also really accurate with this powder, but they aren't any barn burners. The 70's are running about 3,250fps and the 85's more like 3,000-3,100 max.

My Varget/70NBT load was up to about 42.7 grains as I recall and running more like 3,500 fps! But I couldn't get rid of the occasional flier that I know now, wasn't me.

I plan to try the 70's with IMR-4350 powder at some point, but suspect I will have to be way up above the published maximums to get back into that 3500 range again, but if I could get RL19-like accuracy at Varget speed, well... that would really be the ticket!

The RL19 is a little slow, but great case fill and for somebody like me who weighs all their charges out one by one, I find it a very easy powder to work with.
 
If you look in the Nosler manual, they list a load of 47.0g of H4350(3600 fps) with the 70g Nosler as an accuracy load....sure is in our 700's, but I would start off at 45.5g and work up. We seat bullet touching the lands. The win large rifle primer is what made the load cometogether in this combo.

Which edition is that? I have 4 and 7, neither one lists H4350. Mine show IMR 4350 with 47 gr as an accuracy load, not H4350.

I do have some IMR 4350. I will have to work some up.
