Re: Tackling Scope Cant

Everything I regularly shoot at > 200 yards gets one of these:

I true this up with the EXD device I posted above. Thereafter, I know that if my bubble is level, my crosshairs are as near vertical as I'll ever get them.

Re: Federal's 204 trajectory data

Bryan Litz addresses this in his book on long range ballistics. The lighter/lower BC bullet ordinarily will shoot flatter at the shorter ranges but, at longer ranges, due to its higher BC, sometimes -- and I emphasize sometimes -- at extended ranges the heavier bullet will have the flatter trajector...

Re: suppressor increase velocity ?

...how much reduction in recoil with the 204 ? 10% to 20% ? how about the point of impact with regular ammo does that change as it does with the subsonic ammo ? so what is the advantage of using a titanium suppressor instead of steel ? is it just strength ? I wasn't aware a .204 had recoil. Then ag...

Re: Lead Free Bullets

All other things being equal, a longer bullet is harder to stabilize. Weight has nothing to do with stability. Weight only counts when you're talking bullets of the same diameter and made of the same density material, which doesn't hold here. But I doubt such a light bullet will be long enough to ca...

Re: Temp sensitivity in powder?

...I am surprised at one thing though. I think this is the longest I have seen a thread go without 10x popping up. RL-10X is extremely temp sensitive, so there was no need to interject it into this thread. And it is bad netiquette to ASSUME you know better than the OP what his question should have ...

Re: case necks

Same here. I bought a Lee collet neck die for a .243 WSSM, a cartridge that needs help with case life if there ever was one. As well as a Redding body die for the shoulder bumping. But my groups shrank a bit, got a bit more regular in size and fliers became less frequent. So I bought more for my oth...

Re: suppressor increase velocity ?

Not so much a factor with the .204 but I find the main reason I continue to use a suppressor is the reduction in recoil. Plus, it makes everything I put it on a tenth or two of a MOA more accurate. But they are a PITA at public ranges. People tend to treat you either like you're a rock star or Tom B...

Re: Temp sensitivity in powder?

Varget has always known to be very temp insensitive. XBR is developing the same reputation, maybe even better, but I've not heard anyone who'd tried both in the same load remark to it. I doubt the difference would be worth your effort working up a new load. Unless it's a rainy Wednesday and you got ...

Re: suppressor increase velocity ?

The supersonic crack isn't affected by the suppressor, only the muzzle report. There's a ton of hot gasses fighting to get out from behind the bullet, and they make a pop all their own once the bullet gets out of their way. That's all a suppressor controls. Once it's a foot downrange, the bullet won...

Re: suppressor increase velocity ?

In the case of most "modern" suppressor design, yes, they will increase "muzzle" velocity by a few tens of fps. The phenomenon is known as freebore boost. The first chamber beyond the muzzle tends to "stack up" the gasses behind the bullet so they continue to drive it f...

Re: Starting Loads

Rick is referring to something known as the " secondary explosion effect ." It is documented to occur but is not reliably reproducible, which means they can't precisely define its limits, which means you don't want to go anywhere near it. I've seen a "rule of thumb" that you shou...

Re: Lands

If you do go with the Hornady comparator and a modified casing, I would highly recommend using fired brass from your rifle to make the modified casing from. I don't have the tools to make my own, so I sent a couple casings into Hornady and they made the casin for me. If you don't do this, then the ...

Re: strange scale behaviour

bow shot, there are load development methods that lessen the impact make such minor differences in loads. Optimum Charge Weight, for instance, is specifically geared to selecting a load that is tolerant of the inevitable small variations. My second point is that I'm thinking your problem is caused b...

Re: The 4000FPS barrier Ruger 204

Wayne, at this point, I'd be curious to know a little more about your chrono; brand, age, etc., what other cartridges you're shooting over it and what results you're getting. There's not an easy way for Joe Sixpack to tell how accurate his chrono is but one rough gauge would be to run a few 32-gr Ho...
