just as expected can't shoot berger vld

Reloaded a bunch of berger 243 105 gr in various powder loads form minimum to max... Every single bullet tumbled to the target .. I ll say rifle twist will always stabilize a bullet, may shoot eradic but not tumble... I mean if I wanted to relive Vietnam than tumbling bullets are it.. Than I loaded 80 psp and shot .25 moa, should I even try lower weight vlds .. Twist is 1-9, also I believe its wasting my time and money shooting anything heavier than 90 gr.. Just not enough powder powder to push a heavy bullet in 243.. Any recent experience ??

You are approaching the VLD from the wrong standpoint. You have only done half the work. What you described is a pressure test for the VLD. now you need to run the seating depths. Read the info in my signature line. Take the results from your pressure test ie. the max safe load and back it off half a grain. Then do the seating depth test as out lined.

You would be better off trying the 95g anyways but you may get lucky with the 105. Also you need to be shooting at 200+m on these test. If your bullets are key holing you not going to make it work. Its worse than Nam in that case because they are not supposed to yaw until they enter.

The best group I got with these tumbling bullets were @40-41.5 of powder the seating was 10 were touching the lands 10 were 4thousand off 10 were 50 thousand off. And still no key hole just wide bullets shaped hole like sideways

Re: just as expected can't shoot berger vld

Does it not say right on the box that the 105's are for 1:8 twist Minimum ? Your Ruger is a genuine 1:9 but thats not going to cut it with the 105's for sure.

Which 95's do you have ? You should be alright with those, but what barrel length do you have ? If you have a 22" barrel your velocity will be sub par and with that the RPM will be below expectation. Heavy bullets and short barrels are not a good partnership. The stability calculators will want to know the actual velocity from your barrel.

WOW, that sucks. We shoot the 105's from 1-10 twist 243's no problemo but I got a little elevation. The 95's should be fine, have you verified the twist rate?

Bigngreen how deep you seat your 105 ??. Also what powder your using ??.. I was shocked at the tumbling on paper. I expected smooth holes.. I understand its a 1-9. I know that should not cause them to tumble..
