Well, I think we are at 77 gr of H-1000. This rifle with a 180 Berger VLD the bullets are seated .115" off the lands. To get the dial ups to match the exbal program using the Berger G1 BC of .659 for the180 VLD, we used a MV of 3175 in the program. It has been my experience that every time I use a chronograph for MV in ANY program, I end up lowering the MV to get it to match the drops. So is the rifle sending the 180's over 3175? Maybe...??
I feel this load of 77 gr with a 180 is very safe as far as pressure. I know I have been well above this with a 210 vld in a 300 win. But I have also seen a facroy 300 win show pressure with a 210 Berger at 76 gr. So I dont know how far one could push it, as each rifle is different. But when I find the accuracy at 300 yards and beyond I stop pushing. I will take accuracy over velocity ant day.
A few weeks ago we set a target up across the swamp at my friends house that I sold this rifle to. About 3 evenings ago we had a calm no wind evening. I got a call from mt buddy. He told me he had just sent 4, 180 Bergers to the target. He then went over to look and covered the group with a Scoal can. The target is at 700 yards...
This rifle is a shooter, and I will build another. I believe the 300 win case is a perfect match for a large 7mm bullet. Good efficent case fill, good velocity, supurb accuracy. I have had my go with over cased rifles. I even had a 257-300 Weatherby once. I now prefer a rifle that will have a good enough throat life to get it developed, do plenty of practise and hunt with it before I have to rebarrel and start over. I believe that the 300 win case is as far as I want to go with a 7mm. Might even be considered perfect by some.
