RRCo: the gun was a .303. It kind of started my interest in the .303 cartridge, and obviously that shifted to Enfield Rifles.
Currently going thru load development for this gun.
My intention is to end up with a Cast Boolit load, and one or two Hunting Loads. The Hunting loads will be based on Hornady 174 gr RNSP's, and Woodleigh 215 gr RNSP's. However these bullets are not available anywhere right now so I have to wait until they become available. From what I have read the Woodleigh 215 gr bullet appears to be the hunting bullet of choice for you guys up North.
The Cast loads are done with the boolits shown above and XMP5744 powder. I have Winchester and Frontier (Hornady) Cases all but a few of the cases I have right now are new unfired.
I shot up my first loaded rounds last week and whereas I got zeroed at 50yds with only a few shots, the 100 yard group was more like a pattern. My conclusion was that I ran the boolits too hard. I had made the mistake of loading the previous run like I do my .30-06 with 25 gr of 5744. The .303 is more like the .30-40 Krag than the .30-06 so charges befitting that round are more appropriate.
So ,,, I backed off on the charges and started at the bottom, loading 5 each, from 19.5 to 22.5 gr of the above mentioned powder. One of these charge levels should work. If not then I will go to the "Universal" .30 cal. Cast Boolit load of 16 gr of 2400 which seems to work in just about any .30 cal. round.
Next day,,,
Shot the gun today with 7 different loads and the best I got was one 2" group at 50 yds. Shooting off a good rest with a rear bag in ideal conditions.
I think a good portion of the poor groups was the targets I am shooting at which don't allow me to index the Front Sight on the target very well. The best group was with 20.5 gr of 5744 powder and 314299 boolits. But 21, 21.5 and 22 were nearly the same size. Easily could have been poor sight alignment.
That said, I still had no problem hitting our 300 yard gong (36" hanging plate) 3 times in a row,,,, Offhand!
On another note:
I have to tell you guys ,,, the main reason why I bought this gun in the first place was my interest in the Canadian Rangers and their function in your society. I wish we had something like this here in the US, but it would probably be deployed on our Southern Border in the desert instead of a pristine wooded northern wilderness keeping the Ruskies at bay. You guys get to do Military type things without having to be in the Military perse'. If I lived up north I would be there with you.
I might add that I was the person who tried to get Ruger involved in the refit of the Canadian Ranger Rifle. As soon as I heard about the proposed upgrade a few years ago, I called my friends at Ruger and told them about the possibility. They got right on it. The Ruger Gunsite Scout is Exactly the gun they are looking for in it's current form, with the exception of a synthetic stock which your military wants and that Ruger could easily supply.
Apparently that refit has been shelved as Your Govt wants the gun to be made in Canada. The only US outfit that has a plant in Canada is Colt.
Colt's only mag fed bolt action offering, which is actually made by Dakota Arms in S. Dakota, is $2700 US and not completely to Canada's Spec ,,, Ruger's gun is to spec and is $1100. Big difference when talking about 5000 guns. Probably a quantity break to be had there as well!
On yet another note:
I will have Front Sight adjusting tools ready in about a week and will post pics as soon as they are ready to go. There has been a lot of interest in the tools at other places so I think you guys will like them too.Front sight adjuster tools are at the plater getting anodized.
I am starting to work on a Backsight Adapter Plate to mount my Redfield Olympic Sight. I think a combination of a better Backsight and a 2-3" black square for a target will yield some better groups. The aperture in the ladder sight is simply too big for shooting targets. Be fine for hunting or shooting people which was kind of the original intent.
Will also be casting some more Boolits this weekend.
