Well last week I picked up a RAP, didn't get a 6.5CM though, I decided to get a .243. Primarily going to use it for predator hunting is why I went with .243 over 6.5 so I can use lighter bullets better suited for coyotes/bobcats. Plus I can use it for deer or pigs still if I feel like it, although I have other choices for that.
First thing I did was modify the trigger, I see some of y'all talking about cutting a coil off the spring to lighten the trigger pull. I did a little more searching and found where a lot of people are just removing the spring instead. This makes it even lighter and has been tested for safety and is perfectly safe. I also drop tested it and slammed the bolt shut to make sure it wouldn't fire. I don't have a trigger scale but I'd say its right around 2 pounds and maybe a hair under. Some guys have tested it at 1.8-2.0 pounds on their rifles after removing the spring.
I also floated the barrel and added a lot of weight to the rear to balance it out as I will be shooting it suppressed. Lucky for me I have a ton of old wheel weights laying around to fill the stock with. My rifle now weighs 11.5 pounds with scope and suppressor on it.
I may still get a boyds pro varmint stock for it, haven't decided.
I'm beyond pleased with this rifle, shot 1/2 groups for the first shots with factory ammo. Can't wait to work up a load for it to see if I can improve it.
The day after I zeroed it in I drove up on a pregnant sow that was bedded in a field and she took off into the field and stopped a good ways out so I guessed the range and took a shot. Dropped her and then ranged it at 379 yards.
These guns are flat shooters. For the price I don't think they can be beat.

Max COAL or Max CBTO for the 6.5 Ruger Predator
Originally posted by Rswan13 View PostHow long are you loading those rounds? Mag length or out to the lands? I'm measuring a pretty good amount over mag length to get my 140 ELDM to get to the lands on my rifle.
We made our own Modified Case for the Hornady O.A.L. Gauge Tool
What I did to get the MAX COAL or MAX CBTO for this rifle is the following:
I got a fire-form case from 143 eldx factory ammo,
Clean it, trim it to 1.915",
Do not touch Headspace and do not touch neck on brass
Drill out the primer pocket with a .290" Letter Gauge L bit
Tap out the hole with a 5/16″-36 TPI Threading Tap
Using the hornady, I measure 10 different times(2 different bullets) and got the following
with the 143 ELDX max COAL is 2.895" OR CBTO is 2.250"
With the 142 SMK max COAL is 2.875" OR CBTO is 2.260"
WE ARE LOADING OUR RELOADS AT MAX "KISSING LANDS" COAL FOR LADDER TESTING, THEN OCW TESTING, AND FINALLY WE WILL DO A COAL/BULLET SEATING DEPTH TESTING FOR MAX ACCURACY
My self, I have always use the CBTO measurement or Cartridge Base To Ogive because this is measurement that relates to the actual touching lands or jump to lands or Jam into lands measurements
here is a good article about this:
