Hank another wildcat just what the world needs. 300 Norma is a interesting case but it really becomes a specialty item when there are really better choices in the 7mm family that can get the job done most of the 7mm mag cartridges available now are over bore why did you go with that?
We only had one die hard competitor at our 1,000 yard club that tried like hell to make a 7mm competitive he finally gave up and went to the 300 WSM and he is winning matches now. I still have two long range rifles one in a 7/300 Whby and one in a 7mm STW great hunting rounds and unless you really run a barrel 30" or longer your not getting the performance out of those cases the 300 Norma will be no different.
Here was my best of four targets at a 600 yard match yesterday. The four target s averaged 2.235" with a score of 185 out of 200 and I only placed 9th. out of 36 shooters. There were three shooters with agg's under 2". (2) 1.7's and a 1.8". Lots of tough competition down here. Of course I'm shooting a 6mmBRX (shoulder pushed forward .100 and neck shortened .100") with 33 gr. of Varget and a 105 gr. Nosler RDF at 2950 fps. With a 16 1/2 lb. rifle.
Richard is correct... Here at Hankins Custom Rifles,,, I let the customer design his dream rifle and as long as it is not something really crazy or something I know won't work I will build it for him. Looks to me like this guy hit the nail on the head and the proof is in the pudding and the shooting of this rifle was outstanding right out of the gate. This man has more shooting experience than me and most people out their, I know he did his home work on this rifle and I also know he will be shooting bugholes with it.... Although none of us will ever see them, this guy is not much for posting groups or into the social media. He sticks to him self and has his own personal 1200 yard range. He can sit in one spot and shoot any distance he wants to shoot out to 1200 yards and his terrain is perfectly flat.
And this guy likes to experiment with new and different stuff,,,, That's why I built the 7mmX300 Norma Mag for him...
Hank I can fully understand that. I did a lot of experimenting with wildcat designs back in the 90's one was the 300BN with was very successful at 1,000 yard competition. Same goes for muzzleloaders I try to make each one a little different to personalize the gun for the customer unless they want two exactly the same it would get boring if you built the exact same thing all the time.
Richard nice target the BRX falls right in with the Dasher. You know I have been running both the 6mm Dasher on the Lapua design and on the 6mm Norma Dasher with the longer neck Not any real difference between the two the Norma case is heavier and has a little less volume so to get the same velocity you need .2gr less powder that the Lapua case. I did shorten up a batch of new 6mm Norma brass to 1.540 and turned the necks down to .010 I fired 20 new cases just to check for velocity and to fire form them out they are very close but they still need fire forming at any rate the Norma brass gave me much small deviation than the Lapua over a 20 shot string. Now the real test will see if that translates into smaller groups at 1,000 yards.
I might take my Dasher to the shooting school this weekend and let them play around with the 105 Nosler RDF I want to see if they will shoot in this one barrel.
Jeff your probably not aware of it but we run a two day shooting school at our 1,000 yard club every year. We only take 24 shooters. It is a very informative two days. lots of benchrest reloading tech's and proper bench setup and shooting styles and then a match held on the last day everyone learns something from this it might be something you might like to try in the future. It usually always around the second week in June. You could also test your muzzleloader at 1,000 yards that would be fun.
