I am currently running:
- stock Savage LRPV in .223 with 1:9 twist
- Nightforce 5.5-22 X 50 for glass
- harris bipod
- Sierra Match King 77gr loaded with 25 gr varget kissing the lands, Win. primer
- 2850 fps across the crony

I have attached my best string from today. String was shot with no corrections, just 10 rounds sent to same point of aim.

I am entertaining running this rig in Fclass restricted.

Now for the question:
-what should i do next?
-bed the action?
-work on my load some more, if so what range should i be working it up at?
-something else?
 
Just a few thoughts -
77SMK is designed for ARs. It can be seated to work through the action. There are other bullets you might try, 75 AMAX, 75 HPBTM, etc.
It might be better to either use a "jump" or a "jam" for seating. It can be hard to get a really uniform "kiss". If you jam, watch pressures.
Apart from the stray in each group, you are holding 1 to 1 1/2 minutes vertically. Obviously you will have to work on wind to make the groups round.
Are your cases uniformed? Prepped? FL or neck sized? Rem. may not be the most popular case for F.
You could try slight variations in powder charge, perhaps BR or match primers.
 
First off find some CCI Match or Magnum primers. I found that with Winchester primers my ES was about 100fps. With match and/or Mag primers, ES was below 10. Have you chronographed your load?

You vertical on looks good other than a couple of flyers.

The 77grn Sierra's were designed for the AR as mentioned above but there are Sierra 69 and Berger 70grn bullets that should do well in your rifle as well. Sierra's traditionally like to be jumped, try seating them a little deeper into the case and see if the group tightens up.

I have found that 200m is a good distance for load work up as you can still see your hits through the scope but is enough distance to separate a bad load from a good one.
 
X-fan ---- How heavy is your trigger? It is the stock savage accutrigger that came with the rifle, 1.5 lbs ?

CyaN1de ---- First off find some CCI Match or Magnum primers yes, i brought home some match federal primers from kamloops

What incriments should i step when adjusting seating depth ? 10 thou?

tiriaq ---- I had started off with a range bullet brands and weights. For the Kamloops shoot i went with the heaviest bullet i could push that seemed to group fairly well due to the wind that they tend to have there. I currently have stock of Hornady, Berger, Laupu & Sierra. Weights for 40-80 grains.

Thanks for your responses guys.
 
One thing to remember is that shooting off a bipod isn't that easy, it takes practice. Everything has already been covered above from different bullets to primers to trigger. If the rifle isn't bedded you should look into doing it.
Your second group looks better for vertical than the first group, I assume the first group was shot with a clean bore. Now don't clean your bore until the groups open up.
 
Bed the rifle, grab some wind flags, practise, practise, practise.

If you can get your Savage to consistently hold 1/2 MOA over 15 to 20rds, you are done. I just don't know if the barrel will stay put as it heats up.

I would recommend the 75gr Amax or Berger BUT if you have the MK's and enjoying the performance, learn how to drive it.

A great start. Now you just need to learn how to read the winds...practise, practise, practise.

Contrary to some opinions on here, I actually do see a benefit to testing a load at 100M. You are less impacted by wind, and if the group is crappy at 100, it is going to be crappy at 300. a 1.5 MOA group will NOT shrink to .25 MOA at 300, but optimizng velocity can certainly ameliorate the effects of wind. Yes, VLD bullets settle down at long range, but not a whole bunch. Ladder testing has to be done at longer ranges (300M minimum) and in calm conditions, but the load fundamentals can be tested at 100 - no problem.

Your vertical dispersion on the second target is more than acceptable, and if the horizontal dispersion os from wind, there is nothing wrong with your load.

I typically use .005 increments makes for nice easy round numbers. .000, +/- .005, .010, .015, .020, .025

I have had success with The sierras jammed as well but I think the consensus is that the HPBT's like a jump. I know one shooter was saying that they used a .040 jump.
