What length should I chop this barrel to?

[N2TRKYS]

If you hand load to the same levels you could get a 143gr moving close to 3k from a 20” 6.5prc.

Not even close from what I’ve seen with the 6.5 PRC, but glad you’re able to get it.

Yes so if I reloaded, I could easily get 2850-2900 out of a 20” barrel. But I don’t, so I’m conservatively saying 2700. I’m sure there are better choices for short barreled cartridges, but this is what I have an am running with.

You missed the whole point, but good luck, anyway. Report back what velocities you get after you chop the barrel.

I get 2835 from factory loaded 140gr tipped fusion in 20”.

My 18” 6.5-06 gets 2750 with 140s. I could probably lean on it a little more and get it to 2800. 2” of barrel would add another 50 fps. Then the prc case has a little more capacity so I could see it going a little faster still.

The main thing for me with this rifle is I hated carrying it around when it had a 28” barrel. I also hated carrying it around with a 24” barrel and a suppressor. I like it much better with an 18” barrel and og65 on it but I have contemplated going on down to 16”. I suggest cutting it down to whatever length makes you like using it the best and don’t worry about it. A 20” prc will still be faster than a 20” creedmoor.

UM getting 3030 from 26” 6.5 PRC with 153. At 18” with suppressor would be around 2850.

That was the thought when I purchased it. Get 24" creedmoor performance from a smaller package.

I was just looking at those loads this morning. Not any more expensive than factory-loaded Bergers. I might have to try some of their loadings when I get it back.

I shoot a Blaser r8 which is 3-4” shorter than standard bolt action. Why I went with 20”. If I was running standard bolt action I would go 18”.

2850 out of 18” with 153tmk would be bad medicine. I haven’t run the numbers but my guess is you would be over 1800 to 800 yards.
