Thread: 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.

We tried your Weatherby 257. 1" group with factory 100grn.

@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.

Did you check the freebore @Tahr? might need to shorten coal a few thou".

@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):



Done and dusted
