Re: Sticky chamber?
You are correct in the fact that I have not cleared the issue of using non-plated brass regardless of manufacturer. However since switching to nickel brass I have not had any of the issues in #1 post.
I switched to WW760 powder and CCI-250's as this is the load that shot extremely well in the factory barrel using any brass. The load shows no signs of pressure and is 1.5 grains below book and what I had shot in the factory barrel. Being a custom barrel/chamber there is no comparison between the two only reference of past data usage. It is doing what I wanted just with nickel brass.
I will try the non-nickel brass again once I have the nickel brass load confirmed for grouping. Got 30mph winds past 3 days here suppose to die tonight.
It (.243) will probably shoot very well for you. However being 26" of length defeats the purpose of the original design of the rifle for my usage. Here in thick southern Pa.'s woods of hemlock and oaks we hunt from trees for whitetails. A shorter barreled rifle is my preference. The cartridge is where the difference is made.
The original (steel receivers) BLR's were chambered in .284 for a time. I had thought about a 6.5x284 but the barrel needed to be longer to get the full benefit which is what I stated before I didn't want plus the rifle would be front heavy. This rifle I have is very well balanced. Got rid of that browning gloss too, matte bluing and satin wood. I'd be curious as to what kind of performance you do get out of that rifle with 95gr. ballistic tips.
