AusVarmint

I have it here ...I used to use it on a wssm but heres the thing. If you are chasing velocity then you need to understand that hbn reduces the friction of the bullet. Therefore if you want the same velocity you need more powder. Most rifles that are barrel burners as you are no doubt aware eat away ...

Fantastic..... well don't hold back tell us your thoughts.

Cant comment on the 600 but I have the Varmint....no issues under light

Nice stick mate..I have the same in 223
When you start reloading for it let me know and I will send you a few samples to play with.

Trev,
I run the hd5-25 x 50 target turrets and a varmint reticle.
Gives me hold overs for spotlighting or quick shots and the ability to click when I have the time.
Happy for you to have a play with it if you want to meet up at one of the locals.

Wash a couple of them with metho or a citric acid solution and see if you can get it off.
if not its probably hydraulic dents from the forming process ....well the bergers are better at hungry jacks.......

The .223 wissum would certainly be a bit different and probably a real hoot to shoot (and the bloody cases don't have thick necks I believe?) :lol: Its loud and obnoxious it eats powder like there's no tomorrow...you need to consider putting $2 into a jar for each shot to pay for barrels and the mu...

Ringed bullets means the neck tension is different to the others...thus different poi :wink: bt, Not if its the seater that is doing the "ringing" i.e. a "sharp edge" that Waldo has taken care of with his builder bog formed - seating die. However in the name of science, I will c...

well you could just use a soft load but when I fireform cases since I'm paying for a bullet and a primer and powder...well ok maybe not a bullet :lol: ... I usually just load em up to my fav load and cut em loose at cats ..foxes ..pretty much anything that needs a new hole. I just keep the range som...

Im going to send you some 60 gr Varmint R use them to fireform some cases and then try reseating the premiums you have.
Call it r&d to settle my hunch.

You could always go up a size with your expander ball

Id be putting cheap bullets in there and fire forming.
If I rub my crystal ball hard enough I forsee your problems going away when you reload the next time.
I get the same with new full length lapua brass even when I fls

Just go a 223 wssm
All the case capacity you will ever need...and then some

On doing some more thinking on the matter... is this fireformed brass or virgin brass with the bullets pulled?
Given the weight variations yo discussed who knows re the quality of manufacture.
Fireforming just might fix your issue.
