Re: 338 Edge

Thanks for the replys
The barrel on this gun is made by Ted Gaillard. He is a very good barrel maker in this area very well known in the benchrest world. It started out as a 338 ultramag that I had converted over. It only had about 75 rounds through it before I converted it. It was very accurate as a ultramag.
The way that I checked the twist rate was with my Dewey cleaning rod. I put patches on it till I could just get it to go down the barrel. I marked the spot that I started from on the rod,also by the handle. I pushed it in till the mark at the handle was back to the top then marked the rod again and measured the difference. It was almost exectly 10 inches. I think this is a correct way of checking twist rate. I reloaded some of my brass last night starting lower going hotter and also made them longer roght into the lands.I will give this a try today, and keep you posted.

Re: 338 Edge

What bullet weights was it shooting well as a 338 RUM?

That should tell you close enough on the twist rate. Certainly accurate enough to tell if it is a 1-10 or 1-12 anyway!

I would doubt that seating the 300 gr SMK out into the lands will stop this but its worth a try. Not sure what to think really. Especially if the 338 RUM happened to be shooting the 300 gr SMK well????

Re: 338 Edge

Well guy,s spent some time at the range today and the results were very good. When I reloaded this time I loaded a little hotter and made the oal 3.920 instead of 3.880. What ever the problem was was fixed is the long and short of it. The first rounds were at 89.5 grs seemed okay so I went up from their in .3 jumps up to 91.7 all with a oal of 3.92. When you guys said the velocity should be in the 2600 range you were almost bang on.
89.8 2672
91.1 2699
91.4 2726
91.7 2749
None of these loads showed any pressure signs so that is a good thing and I am happy with that load of 91.4. I fired 4 rounds of this load and had 3 at 2726 and 1 at 2726 so that is hard to beat.
Looks like this gun is going to be a shooter after all.
Thanks all for the help

Re: 338 Edge

With your OAL you will probably presure up at 93 or 94 grains. You can also expect to run about 2800 fps or so. I am baffeled on your problem, I have run much slower with a 1-10 twist with no problems. At this point if it isn't broke don't fix it. Watch for the bullet to become unstable at distance when it slows down, it seems to me that this will occur for you at a given velocity reguardless of its location to the muzzle.

Re: 338 Edge

I only shot out to 200 yds today but the group was just under 3/4 of a inch for 3 shots. Nothing special but I was more interested in other things than group size. It will be getting the test at farther distances in the near future.

Re: 338 Edge

Hi all,

I am new to the 338 edge. as a matter of fact, the rifle is not finished yet. I need advice on where to start reloading. 338 RUM or 300 RUM brass? Can I fireform 338 RUM in an edge chamber? Whose dies are recommended?

Thanks in advance!

Re: 338 Edge

The 338 Edge is the 300 Rum necked up to 338 calibur with no other changes
No you can not use the 338 Rum case as it is shorter than the 300 Rum case
range it,check the wind, dial in correction, aim and only one shot
