300 PRC Build

[rpierce]

So I finished a lightweight 300 PRC for myself a couple weeks ago. I wanted to have a pretty lightweight setup for the occasional mountain hunt. First load I tried shot in the .1s at 100 and has been consistently 1/4 moa or better. It was a very mild load of h1000 and 230 berger OTM at 2700 fps. I loaded up the rest of the 100 rounds of lapua brass with that load. Took it down to Texas and killed an aoudad with it.

Rifle has the following:
Pierce Engineering Titanium Action w DLC, timed to a TT Diamond
24" Proof Sendero contour
Titanium Self Timing 5 Port "Muscle" Brake
Manners EH1 with elite cheek piece
Hawkins DBM and 5 round mag
Tangent Theta 3-15M bedded into a set of NF rings

These Pierce Engineering, no relation, are an extremely high quality action. Dead straight and the ignition is flawless. Comes with .250+ firing pin travel and zero cock on close for a Triggertech trigger. Way better ignition setup than some of the other titanium actions Ive seen on the market.

9lbs 10 oz with optics.

So I decided to do a true cold bore test with my 300 PRC. One shot per day for 3 days at 580 yds. After the 3 days the 3 shot group measured .816"/.134 moa. Had up to .4 MIL worth of wind on the Tangent Theta 3-15M throughout the test. Wind came from all different directions. I also zeroed the scope after each shot. Scope obviously tracks dead nuts.

After the 3 shot group i figured why not do a 5 shot group.
So after one shot per day for 5 days the group measured 2.4"/.39 moa at 580 yds.
4 out of 5 shots measured 1.1"/.181 moa.

I had a friend up yesterday that wanted to do some load development on his rifle. After we were done I said lets both shoot a shot through my 300 PRC. One shot per shooter. Both shots measured .896"/.164 moa at 580 yds. Two different shooters on the same gun.

Awesome! What is the overall length with a 230 berger?

 

[rpierce]

The 230 OTM is alot shorter than the 230 target hybrid. The COAL with a 230 otm is 3.64 at .020 off the lands.
