Hot Stuff

I bought a near new/second hand XBolt stainless in 270wsm. Docked the barrel back to 22" and used loads that had worked well in a previous Sako A7 (now a 300saum) and loads I pinched from Ryan off here. 150 VLD and LRAB. New norma cases. Saami OAL.

Velocities should have been around 3050fps according to my data I had from the past, quick-load and Ryan's experience. But yikes! Every case had vicious ejector marks and flat primers and velocities were all 100 fps faster than expected. Up to 3149fps. I tried N550, AR2225 and HV100

So I need to drop all of the loads I tried by at least a grain. Its a good lesson about every rifle is different. This one must have a tight chamber.

The good thing was that it shot very well, especially with the new trigger spring that @Boaraxa put me onto from the States.

Good stag medicine B. I don't get any ejector marks (possibly because mine is a sako so ejector isn't part of the bolt face.. but primers are fine also. However my brass has had a hard time and I'm finding it very hard to full length size, I full length size it every firing and it's all had four firings so far. I think it's time to aneal or buy some new brass, die is set up how it has always been but I think the brass is getting very hard and "springing" back a bit after running it through the die.

You have so many fine accurate rifles it will be hard to decide what to take.

@nor-west Only 5.
I don't know why I do it. My standard is .75moa consistently which isn't really that hard with a modern rifle and good scope and loads, eh.

I gave my 300saum with the Tract 'scope a hell of a bash the other night in the dark. Garked the suppressor and carbon stock. Checked it yesterday and zero was perfect. So far its withstood a good soaking, lots of dialing and a good bashing. Early days but its looking like a good one.

@Woody Cheers for this. I will. I had assumed that there was plenty because I wasn't at mag length. But as you say, I had better check that assumption.

Really good advice right here guys, thats what its all about.

Finally sorted. The 150VLD were jammed by 10 thou (thanks @Woody).

Eased them back to touching, dropped the charge to 68gr (started at 70.5).

No pressure signs now. Velocity 3025fps (22" Barrel).

Last sight in target @100yds (pic is sideways):
