Hello chaps, getting a lot of gas coming back past the case using N160 and 100gr interlocks even at maximum load so I think the powder is a little slow, is there go to powder for 100gr 243 bullets, not gain the problem with 55gr bullets and Varget,
Cheers
+1 for Varget. Used it for years , no issues.try varget! you have it already so work up a load with it.
is your brass over worked as 160 is a great powder for the heavier bullets if you use varget you wont get anywhere near the same case volume its far to fast,if your struggling pop it round I will have a look at it for youHello chaps, getting a lot of gas coming back past the case using N160 and 100gr interlocks even at maximum load so I think the powder is a little slow, is there go to powder for 100gr 243 bullets, not gain the problem with 55gr bullets and Varget,

using new lapua but seems to be a little better when worked up the same load with old winchester brass! maybe the winchester brass is softer and sealing better!is your brass over worked as 160 is a great powder for the heavier bullets if you use varget you wont get anywhere near the same case volume its far to fast,if your struggling pop it round I will have a look at it for you

Thank you for putting my data into quick load, appreciated. I did try 43 grains but I found signs of pressure on the primers and got gases still passing past the case, i'll Look into trying a different powder, cheers.thanks for that which has just told be your running way under pressure hence why the case isn't sealing on the chamber wall,Ive just ran your numbers on quickload at the moment you have a chamber pressure of 3309 bar.
stick 44gr in and see the difference
