Thanks guys! No I am hoping that this Finn barrel will be all it needs, should be accurate as it has excellent rifling and my other 2 are boringly accurate... I shot some silver tip surplus and it showed promise, handloads with varget will come next... Did have a lot of muzzle flash from the surplus with this length barrel... Range reports soon...

well had a chance to do some load workups today for the custom m39, started at 42 and worked up to 46.5 gr of varget under hornady 174 gr .3105 fmjbt. this group was with 43 gr, but the 46.5 showed a lot of promise... what is the max amount of varget for 7.62x54 and 174 gr?

Hmmmm I might have some load data for Varget.. let me look.

48.3 with a 165 grain
46.5 with a 180 grain, showing it as a compressed load. Depends on how deep you're seating it.

The 46.5 you were using is towards the upper end, I'd certainly be looking for pressure signs.

Did you slug the bore on the M39? No telling, could be from .308 to .314 groove. Too loose is going to affect accuracy, too tight is going to increase pressures.

Horizontal dispersion looks pretty good- meaning I don't think it's the rifle- it's the load. Try to find the load with the least amount of vertical dispersion.

How are you determining seating depth- are you using a bullet comparator to determine jump?

With this particular bullet, I can't reach the lans so I have it seated deep enough to get a crimp. And those are different groups with the ss adjusted so I can use the same point of aim and different impacts so I didn't have to keep walking downrange... The group beside the dime is the one I'm showing off, pretty good for a surplus rifle... Also the m39 is a Finn and they have .310 bores... The Russian bores/ barrels didn't have the tolerances of the Finns.

ahhh...

I misunderstood. I thought ALL those shots were from the same load...

Nice...

Oh man no biggie, I should have been clear when I posted it... I'm excited it did this well... Hope to get my hands on some .311 174 gr smk since most people say they will outshoot these hornadys...

Those are some very nice groupings. All three of the groups.

Well for the first time ever I took this renewed m39 to the range and shot her LONG RANGE! My son has been wanting me to stretch this old girls legs a bit, so this past Wednesday I did just that... I had on hand about 25 handloads that this rifle loves and started @ 300 and worked out to 700 yds before I was done! There is a velocity loss due to the short barrel when compared to even my 24" m28/76. But, it was just as accurate as well! I love the way these old finns shoot. The only thing I didn't care for is the muzzle flip I have gotten from every barreled action that I've put in this particular bluegrass stock. The butted is just down too low in relation to the check weld and gives a fulcrum that it pivots on. But all in all I am very pleased with the overall performance of this shorty m39! :thumbup:

Sounds like you've got it going in the right direction there , Farmerboy . Those new ELD-X bullets might be a answer to getting where you want to go . Hornady is reporting some almost un-real accuracy at long range with them .

So what did you settle on for a load , and were you getting any pressure signs ? Inquiring minds want to know ... :lol:
If not me.....Who ?
If not now ....When ?
