Thread: 6.5 Swede loads

I chronographed my 6.6x55 load the other day. 140 grn AMax & SST, Norma cases, Fed primers, N560. 2830 fps/21.5” barrel. That’s @ .5 grn under max for my rifle.
Bullets touching at 100 yds.

Fair moving Tahr, I'm managing 2700 and a bit with the same component's and a bit longer barrel I might try pumping it up a bit.

.5gr under book max or rifle safe max

My rifle max. 50.5
51 sometimes leaves ejector marks.

Don’t try this load without working up and using the same components as I do.

I got up to 53gr of N560 with 130swifts and it the chrony only told me its going 2,800fps. Somethings not right I dont think

Try another chrony. Should be better than that. I would expect 2900-ish.

That's what I would have thought too. I was trying for the magical 3k but to get to my 53gr load and still on 2800fps it was a bit annoying. Especially when book max is 50.2 of N560 in he swede for 2,800+ I was sure I was going to get 3k.

Do you think if I done the same ladder test again but used magnum primers I'll see much difference?

I don't think magnum primers will make much difference apart from bringing your SD down. I can get 2900 easy with 120 grn NBT and W760 powder.

I validate the chrono velocity by using a good balistic program and checking the zero. Like, with my 140 grn load 3" high at 100 should be dead on at 265 yards, and it is (those might not be the exact figures, but you will get the idea).

yes I can knock 2900 with 2209 and the 120gr NBT with excellent accuracy and no bad signs.

Well what are you mucking around with it then. You have something that works. Don't break it. The 6.5 was made for 120 grainers

You lads using 120gn projectiles - are you still supersonic right out the back (1100m +)?

I'm yet to try em

Trajectory and drift characteristics would be roughly equivalent to a .270 no?

Youll upset Toby if you keep at it

Except for maybe 123gr A max it is sort of pointless running sub 130gr bullets?

Just saying because I thought thr whole point of 6.5 cal is high BC's.
