I have no manuals that have the 270WSM data. What length do I trim this brass to?

TIA

BR

Trim length is 2.090 according to Hornady #6.

The maximum length is 2.1" and I trim to 2.095"

Winchester's recommends a Trim Length of 2.090" and a Maximum Length with Bullet Seated - 2.860". These are the figures I use for my .270 WSM. Lawdog

What do you guys think of the 270 WSM? I'm planning to buy one this week.

If the 270 bore and bullets suit your use then the 270 WSM would be a good choice for a big game rifle.

It depends upon specifics that appeal to you. However I would select the 270 WSM over the 7mm RM or 270 Winchester if the application is a moderate weight bullet lauching system for the big game they would handle. Keep in mind that
I am trying to avoid belted cartridges.

My efforts at getting a 270 WSM have not been inexpensive. When the WSM's were introduced my first was a M70 SS Classic in 7mm WSM. I went thru the hammers of hell getting rid of the factory stock and now the chamber is out of round. That rifle has sat in a factory repair facility for months now while negotiations continue. The rifle itself was quite accurate when I did everything required but so then are the others.

Then the MRC M1999's became the fashion so I ordered one of those for the WSM's. When the action came it went back for quality issues and the replacement was not much better. That action sits in my smiths hands as a credit. In general the action would be just fine if I had not heard of the Kimber Montana and the fact that the Montana is lighter and made complete.

Along the way I owned a Savage 12FSS or whatever it was in 270 WSM. That mistake was sold in a few weeks.

Now I have the Kimber 8400 Montana in 270 WSM. From what's avaiable now there is no doubt in my mind that it's the state of the art for a $grand. If one has half of that perhaps the Ruger would do the job. But then you get a throw away stock.

The 270 WSM cartridge sends bullets out the barrel at just the velocities that it should. There is MagPro for those who must have the maximum velocity and indeed it performs as stated. That powder will shoot a 140 gr bullet at 3210 fps instrumental over a 35P with no problems.

Since the Kimbers weight is quite competitive with any 270 Winchester that I have heard of it does seem like a good place to be. I see no way that a 270 Winchester can reach the 270 WSM's ballistics over an accurate chronograph.

In summary the 270 WSM is an big hit. Mine is just right for medium range deer and black bear hunting here and also year round as a long range coyote cruncher.
