6.5cm viht n160

and how are the results ? :)
after reading this the other day it prompted me to have a play with these loads. I also have 26" barrel on my AI, I can load these bullets long, so ive upped the powder charge slightly. COAL 2.890" 45.5g N160 with average speed 2921 fps with a spread of 6fps over 6 rounds. THIS IS OVER MAX LOAD LISTED IN VIT DATA, BUT I HAVE WORKED UP TO THIS!! and with the bullet way longer than SAAMI COAL allowing additional powder. do NOT start at this load!!!
 
My Tac A1 in 6.5 cm, using Berger VLD T 130 gr and N555 is 42.5gr good for 1,000 yards. It’s the only powder I use

Cheers for the feedback :) and of course i hope that all who read these threads understands the importance of slowly building up loads in a safe manner, and absolutely not starting at max :)
 
I run 46.8g of n160 pushing a 130grn tmk out my 6.5x55 r8
Accuracy is spot on
This load was worked up for me by a professional
Never had a issue in 7 years and probably fired just short of 1k through it

That seems pretty stout - that load is Viht’s max for a 123gns bullet.
I use 45gns of N160 for the same bullet and was getting pressure signs at 45.5; interested to hear if you are seeing any bolt swipe marks, flattened primers etc…

None at all, but as I say I’m loading to within 8thou of rifling, giving a long bullet and obviously more cavity behind it. Loaded COAL 2.890. I tried 5 rounds at 46, and although still no signs of pressure, the spread was close to 30fps, with 45.5 I’m getting 6!
Something else to add here, to anyone else who might read this thread! these are lead bullets not copper!!!
 
Personally I just look for the data to start up point and work up . After i have cross referenced in various different guides ( books and manufacturers online data ) even these will vary . To get things more correct i will search carefully for the "too much" on a hot day .
Now most data can be found on the net free , its a lot easier

Nothing all good
Bloody cracking round but needing to change to copper Sadly
Any ideas on a load for a 130 cx
 
Sorry no. I am copperfree thus far….

look within the online data across the board for the similar weight and work the load up looking for pressure sign . As you are working up from lighter loads and checking pressure sign you will be fine , if you don't understand get experienced help .
equal weight to lead with copper is fine so long as you start at the start load . I find this totally fine with modern copper bullet design

And don’t start to close to the rifling to start with
 
Generally I find a happy place with vhit powder somewhere around 1gn more than their max load. Obviously proceed with caution but that’s my tuppence worth
