Re: Load developmenbt progress
Grouping like that should do the trick. Now work up a dial chart and start hitting way out there.

Re: Load developmenbt progress
I always had this target scope on here with the intention of putting a hunting scope on the gun. In fact, its sitting new in the box waiting for load developement to be finished, and I think I am there....

Re: Load developmenbt progress
Unless you really want to change the scope, I think I would leave things just as they are for a while. The present set up seems to be just fine.

Re: Load developmenbt progress
So the next challenge, find some Berger 35 gr bullets. As luck would have it, both of my .204 rifles like the same load. A good problem to have, as I am stocked up with 8208XBR.
Where do you guys get your Berger bullets? They seem to be scarce these days...

Re: Load developmenbt progress
My FFL dealer has a 300 and a 600 yard range, he said I should bring that rifle and load over there to try it out. I think I will come warmer weather

Re: Load developmenbt progress
Nice there Tom.
Now if you and your rifle can do that on a consistent basis, I'd say you've 'found the load' for that rifle. That is especially if you can get them all into one cluster with no 'strays' just outside the group. I know it's a hunting rifle, not a target rifle, but you're almost there in terms of decent grouping, but certainly good enough now to get hits out past 300.

Re: Load developmenbt progress
Just a word of warning about the dreaded carbon ring that can develop just past your chamber throat. It's common with the 204 Ruger. It's hard as rock and can cause all sorts of problems in terms of accuracy. From the breech, shove a patch soaked in bore cleaner just past the chamber till it's in firm contact with the lands and grooves. Let it sit there for a couple of hours. If it comes out black, that's a good indication you may need to do some serious scrubbing with JB Bore Paste to get it out. Good luck!

Re: Load developmenbt progress
I have done a good job of scrub and shoot on this gun. I have my own new barrel break in process that includes boiling water down the bore on day one before the first shot is fired.skipper wrote: ↑Sat Dec 23, 2023 3:26 pm Just a word of warning about the dreaded carbon ring that can develop just past your chamber throat.

As for solvents- off the top of my head I have JB Bore paster, Sweets 5.56, Hoppes #9, CLP, and another one I cant remember right now. Normally I use Hoppes #9 because I have a lifetime supply of it. Are any of those a good idea Skipper? I will keep an eye out for that....

Re: Load developmenbt progress
Rick it seems to be consistent so far, I will keep shooting and watch my results. Would you move the OCL a bit and see what it does? Change the powder in a ladder test manner? I was pretty happy to get this to group twice in a row...totally open to suggestions.
I really do think I am on to something, I have put a lot of work, money, and labor into this gun to arrive at his point.

Re: Load developmenbt progress
I looked all over the web today for more 35 Gr Berger bullets...with no luck. I have at least 120 of them so I will keep my eyes peeled.

Re: Load developmenbt progress
I think Hoppes #9 is good enough. I'm also a fan of Butches Bore Shine and Kroil. I first found out about the carbon ring years ago while cleaning my Rem XR 100. Wife called me in for dinner when I had just started a patch through the chamber so I just left the rod in the guide while I ate. Thing was that I was getting clean patches before I went inside. It took me by surprise when I came back and found the patch had turned black. That lead to some intense cleaning with JB. I always had fliers with that gun till I got the carbon ring completely out. Didn't have a bore scope back then.
