120 pro hunters

[AN DU RU FOX]

Any help appreciated my homeloads for 308 win sp no problems,,, ,In my 6x5x55 140 gr sp sierras plus some 140gr amax no problems,,,,,my 120gr sp sierras are a pain,still getting dirty cases i,ve started low ok,been told to increase the charge so i increased upto max no pressure signs and accurate,but still dirty? the powder is n160 and they are crimped,21 1/4 inch barrel tikka.and loaded to saami specs.my own fire formed brass,cci primers.

 

[Southern]

What powder and primers? Are you crimping the necks?

 

[AN DU RU FOX]

sorry southern yes to crimping and the powders n160,and cci primers ,,,,ammended,doug

 

[Muir]

Too slow, I'm thinking. Switch to a faster powder. I use Varget in my 6.5x55 with 120 PPU's.~Muir

 

[jackfish]

What charge did you use with the N160?

 

[straightpull6547]

What velocity are you getting?

Too slow, I'm thinking. Switch to a faster powder....

This would concur with my experience...

 

[Southern]

I forgot to ask the rifle, and barrel length. If it is rifle, with longer barrel, W760 / H414, IMR-4350, H-4350, RL-17 and RL-19 will give great velocity with accuracy ( W760 and 4350s very good ). But a full load of N-160 should do the job, at lower MV, too. Change primers.

Try and get a fast powder mty H414 is nr the same as Varget on the burn chart and is a good powder as a back up for the .308, I used R15 in my 6.5x47 ,

 

[big ears]

As others have said go faster. IMR4350 or RL17 would be my choice

 

[Uncle Norm]

Check that the overall length is within SAAMI spec. If you are loading them longer than spec, try setting the bullet deeper.
When I had this problem with a .243, I was setting the bullets much longer, chasing the lands. Setting them deeper and crimping solved the problem immediately.

someone mentioned a change to a magnum primer ,not sure who,but was a bit warythe rifles a tikka t3 hunter 21-1/4 inch.

hi norm they are all loaded to within saami spec ,cant set them long if i wanted to the spitzers are shortish,i,m not looking for lands just a different load for the rifle,as i say the 140gr amax and 140 gr pro,s are ok,as are the factory privvis.I have n140 but heard it was a barrel burner.looks like i will have to try another powder for that weight bullet, i,m leaning towards imr4350 as i could try the 129gr interlocks as well then.

I was up to 49grain s with the 120 pro hunter s with N160 was a good combo , I'm now using the 140 gk with Swiss rs60 witch is reloader 17 as others have said I would try a faster powder especially if you have a short barrel

it is a great mix 21-1/4 barrel just a pain with the soot,thanks jimsim.,,,,,,,,,,could i get away with another hotter LR primer or maybe a magnum ?be cheaper than another tub of powder ,i dont want to give up on the 120gr,

Magnum primers work well with ball powder like H-414 in longer cases like the 7x57 and .30-06, without increasing pressure, but don't know that they will buy you anything in the shorter powder stack of the 7mm-08. I was suggesting changing to another LR primer, just to see if you have a box of duds.

You won't be wasting your money if you save the N160 for heavier bullets, and buy a pound of H-4895 for the 120s.

 

[AN DU RU FOX]

Thanks for that i will get some different LR primers,i will check if i can get a different powder from my source.I really fancy these lighter bullets.just to add i,m getting 2.999 col with the spitzers ,all full length sized to 2.165/cleaned/prepped/primed identicaly

 

[Southern]

2.999" inches for a 7mm-08? No, the Sierra 120-gr PH, seated fully into the neck, should be 2.78 inches.

that would put me past the neck base and nearly half the bullet seated?Real Guns - Modern Loads for the 6.5x55 Swedish on here he uses 2.980 that looks acheivable. be gentle with me everyday is a school day for me.And i do realize any changes i make to any componants i have to start loads from scratch ie (LOW BACK UP TO HIGH),
