New to me RA Predator

Litehiker was nice enough to sell me his RAP and I got a chance to shoot it over the weekend to get my scope "close" to zero at 100 yards.

I mounted up an older Nikon 4.5-14x40 MilDot (with those almost-too-thin crosshairs for hunting) on it and loaded up 7 rounds of 143 ELDX over 40.5 grains H4350 in new Hornady brass.

This was just to foul the bore and get my scope zero close so that next time I could start load development.

First two shots were within an inch of each other on the top edge of the target just left of center.  Next shot was a bit high and right.  Next shot was within a quarter inch of the center dot, so I just sent the next three rounds without making any scope adjustments.

The result was the last four forming a 0.328" group.

If that ends up being the best it will shoot, I am pretty happy.  However, I am going to start my load development to see if I get it down to a single hole.

Temps have dropped back down to single digits, so it may be a while before I get back out to the bench!

Good start there.
I'd stay with the ELD-X and just hunt close around the 40.5 gr level.
Have two RAPS and they're both keepers.. (243 & 6.5cm)

I loved my RAP but mine would heat up and start wandering.  The first 3 shots were almost one hole though.  I relieved the barrel channel quite a bit thinking that was the problem but not so.  I traded it but in hindsight I wished I didn't because it was so light and handy and perfect for hunting but then again I have more than a few hunting rifles.  I had my SWFA 10x on it and also shot the 143ELD-X with H4350. 

BTW, I have an old Buckmaster 4.5x14x40 mildot scope like yours and last year the parallax focus went out.  Nikon fixed it and within 2 weeks had it back.  Good service.

I have an American in 308 Win that is very accurate and it makes such a nice light hunting rifle that I wanted the Creedmoor.  You can never have too many guns, they just have to take turns. :)

And if I have to take more than three quick shots while hunting, I may not be doing something right.

I actually have two of those Buckmasters; one is bell adjustable parallax and the newer one is side adjustment.  I like them a lot.

Hey Jason,

How ya likin' that Timmy trigger?  I think it helps a lot getting your good group. You can always adjust it down a bit.

Gotta say, Ruger sure made a great barrel and excellent Y-Block bedding that is a combination V block and action bolt pillar. Very clever. I recall I set the action bolts at 65 inch/pounds of torque.

Try some 140 gr. ELD-M rounds too. It likes them.

Thanks for the bolt torque settings.

Love that Timney. Would go lighter MAYBE if it were going to live on the bench, but it will be a hunter. I am working up reloads tonight so I am ready to shoot as soon as it warms up a little. Have 143 ELDX and Barnes 127 LRX to give a go.
