Re: Load information for 7mmTCU using SR4759
I have 139 grain 7mm bullets. Would you run the same charge of 15 grains SR-4759?

Yes I would. I've also used that for my 140 grain bullets. Should have said that in the original post.

Re: Load information for 7mmTCU using SR4759
Well, I loaded up a bunch of rounds using H322, IMR4895, W748 and SR4759 with a 150gr Winchester plain base projectile and headed to the range.
Best result at 50 yards (indoors) came from a load of 28.1gr of W748. Will try this out at 200 yards as soon as the weather is a bit kinder up here!

Re: Load information for 7mmTCU using SR4759
Sounds like a good load. I used 748 years ago in a 30-30 TC and on a hot day I would get vertical stringing on the rams. By the tenth ram I was shooting way high. Never had that problem with other powders in the 30-30 so I suspect 748 was more temperature sensitive. Just something to keep an eye on.

Suggest you check with Sierra bullets for Loading data. They know what they are doing and they support IHMSA.
