Hey all. I got my tikka changed a while back to a 7/300wsm.
And started having a play around with loads to shoot the Berger 180 hybrid VLD. I quite like how the 2225 powder is looking so far.
We tried 2217 in a ladder test and didn't like how it was all over the place horizontally compared to the 2225.
But I have come to a weight of 2225 that has shown a slight ejector rub mark on extraction, it happened to be the heaviest loading of powder. This was yesterday while using the chrony, the top speed was 2811fps.
Also I had a mate down with his new 223 while I had the chrony, just finishing load development there.
With load development done for him we went and shot some goats today with both rifles, I only loaded up six rounds at what I thought was max for the 7/300wsm. And shot two for three shots (miss read the wind first shot).
But there are no marks on these three cases from today.
Yesterday's temp was 25 at the range. And today up the hill would have been the same.
So questions for people with experience in this wildcat or even 7saum,
Where have you found the upper limit for loads compared to the 300wsm (being parent case) or 7wsm?
What speed can you load to in the 7/300wsm with 180's?
I'm keen to get to 2950fps.
If your wondering why I haven't listed the load of powder it's because I don't what someone to see it here and load without working up.
I have already come up 8grains!
