HOT- CZ 457 Builds - MDT- IBI - Spearhead

Will you guys have barrel options for the threaded 457 actions?

As much as it burns my hind end to buy CZ, will you guys be selling 457 actions only?

If you mean the threaded ones? Only if we have enough left after the builds. The barrels will be Benchmark and Bartlein for now.
 
Someone asked about a Tesro build with a 1 :14 24inch. This was yesterday in the snow. Just plinking around at 50 yards. The bigger dimples 5 shots in a hole. Then I was trying to hit the corners on the single shots in a line.

Cold and a slight breeze, plus snow

Thanks. What's the diameter and chamber for the custom CZ 457 with the IBI barrel that's up for sale?

.92 and the chamber is Calfee II for all IBI barrels. We switched them up a bit for the Benchmark, but we had lots of success with Calfee II and pretty much all of our previous builds are with those and we do not intend to change them as they have been working really well.
 
For balance in PRS, longer and thicker is better. However, I've yet to really find solid data on what chamber is the most tolerant for different ammo types as match ammo availability in Canada is not great at times and you have to shoot what you can get. Proper lot testing isn't an option.

We are staring to offer Eley lot testing. We have been working for a long time to get this going in Canada as there are lots of hurdles. Drop us an email if you are interested. We did a soft launch last fall and so far things are looking pretty good. You call also call us to discuss.

Cool. Ideally, I'd like to do this with SK as their lineup is more affordable.

Would be relevant to apply the program to whatever mid-to-high-end rimfire ammo Tesro is able to procure this year. I'm anticipating having to find a new thing my rifles like.

I think given that ammo availability varies between SK, Lapua, and Eley, it may make more sense to seek barrel systems that use shims to adjust headspace.

Yes that is a nice thing about 457 bolt shims. Lots of folks have been using them. But just like everything YMMV, you still need decent ammo and a good rifle.
