6CM vs 6.5 PRC

[Smitt0331]

New to Rokslide so let me know if this is the wrong group. I am currently thinking if re-barreling a 300wsm to 6.5PRC to cut back on recoil. Primary use is whitetail and elk in the northwest 400yds and in as that’s as far as i’m confident shooting. After listening to a bunch of podcasts and reading forums a new rifle in 6CM has come up with either a 116tmk or 108 eldm. My main priority is a quick ethical kill followed by recoil reduction. Any assistance would be appreciated me and my friends have only been hunting seriously for the last 5 years and are still learning. Any advice would he appreciated before i drop a couple grand on a new build.

I’ve got a few 6cm’s and a 6.5 prc.. 99% of the time I grab a 6cm .. a 16” suppressed 6cm is an awesome setup.

Yea the idea would be heavy for caliber on a 20 or 22in barrel to keep MV up with and unknown 6og-s if i got that route.

With your existing bolt face, 6.5 PRC should work well.

You could look at cutting the 300 WSM down and suppressing it. That will tame recoil noticeably. A muzzle break even more so, but I hate those things almost as much as I do talking someone out of buying another rifle.

I’d probably keep the 300 and buy a short barreled stainless 6.5 Creedmore and a suppressor. That new Federal ammo jumps its velocity to 6.5 PRC levels. Would give you moderate recoil and plenty of velocity to well beyond 400 in a handy package, even when suppressed.

400 yards and in it doesn’t matter. Pick literally any bullet that will expand and don’t miss. Shot placement is the most effective cartridge. Pick whichever one you’ll shoot the most

Personally my 6.5 prc non braked kicks more than my braked 300 RUM. So not thinking the prc is enough of a recoil difference to be worth the hassle. Buy a 6cm, suppress it and you will likely be impressed.

Split the difference and go 6prc, done. Search RS for the data and the group of reloaders.

6CM new build it is then. Spotting shots 400 and in would be ideal. I’ll venture over to the reloading forums and start digging. Thanks for the info gentleman.

Probably UM tikka action and benchmark barrel on a rokstok and see what happens.

Does anybody have trouble reloading the 115 bergers or 116 tmk’s to short mag length?

I have a 6.5PRC, and it's a great cartridge, but I prefer the 6CM. Within your range limit, both will kill with no issues. Do you reload? I have not seen much factory-loaded 116TMK ammo.

I’m a novice but yes i do.

I’m a novice but yes i do.

I found the 116TMK an incredibly easy bullet to develop a load for. Search the 116TMK load thread for lots of load info.

 

[Smitt0331]

Will do, appreciate it

Prc is great.

I would do a 6mm 100%, we have killed a lot of elk over the years with a regular old .243 with soft points. These new heavy 6mm bullets are awesome and are designed to upset at lower velocity’s.

I wouldn’t worry shooting my .243 out to 1K with a TMK as long as I was consistently accurate to that range. Even with a 16” barrel I’m at 1700fps at 1K, the bullets perform well down to those velocity’s.

I’d take the extra round count and lower recoil of the 6cm over the prc all day. I really don’t see the advantage of going with a longer barrel or high velocity round with some of these new bullets.

Honestly if I was planning on shooting 500 and closer I’d go with a 6 dasher if building a custom setup.

You could save a ton of money by just pre-ordering a 6mm tikka rouchtech off euro optic and have it cutdown and dropped in a chassis or good stock.

Love my fast twist tikka .243, if there was a 6CM available at the time I would have gone that route but now that i have the .243 I’ll likely just stick with it and snag another takeoff barrel for when i burn this one out.

20 or 22in barrel to keep MV up

Those two statements don't necessarily jive. Plug in the 116 TMK into a ballistic calculator and you'll see that you could easily accomplish way more than the 400 yard and in goal with a 16" bbl.
