bill1227-- I'm going to take one run at this topic and then I'm going to be quiet on the subject for a while. I just have a hard time keeping quiet after reading your statements that the .204 Ruger can't get the job done, drifts too much, can't keep up with the .223 and 22-250.
I'm not sure you caught on to exactly what Bayou City Boy was trying to get across in his first post, so I'll repeat it and hope I don't offend you. I think what BCB was saying is that you have to look at the BC numbers and that when you use the BC of the 39 gr. and 40 gr. .204 caliber bullets, then the heavier .224 bullets really don't have any big advantage over the 39 gr. and 40 gr. .204 bullets as far as wind deflection and flatness of trajectory.
I have nothing against the 22-250 or .223 (I personally shoot a 22-250 in Tikka Master Sporter), I have to say that the 39 gr. Sierra BlitzKing is about as accurate as any hunting bullet I have shot in any rifle. When I want to "touch a varmint" at long distances, I will choose a heavier projectile than the 32 gr. .204 caliber bullets--my personal choice for that long-range "touching" is the 39 gr. Sierra BlitzKing. You seem bent on comparing the lighter 32 gr. bullet in the .204 Ruger with the heavier 55 gr. bullet for the 22-250, and you need to compare the heavier projectiles in each caliber rather than a light bullet for the .204 and a heavy bullet for the 22-250. You try to justify that comparison by saying:
"the 1 in 12 inch twist of the factory .204 Ruger barrels is limited to bullets in the mid 30's range,"
I wonder how much "actual" trigger time you have spent shooting the .204 Ruger or any .204 caliber rifle with projectiles of the 32 gr., 35 gr., 39 gr., and 40 gr. weight classes????? Maybe you are reporting what you "heard" someone say or what you "read" on the Internet. I don't have as much trigger time behind a .204 caliber rifle as Bayou City Boy, but I have put a fair number of .204 caliber bullets down the barrel of my Savage 12VLP and have practical experience at hitting small and large live targets and paper targets at a myriad of distances and conditions.
You state the you are going to select the .223 and use 50 gr. bullets or maybe even the 22-250 over the .204 Ruger because the .204 Ruger can't shoot a bullet in the 39 gr. or 40 gr. weight class accurately.
You are very sadly mistaken about the accuracy capabilities of not only the .204 Ruger, but probably all .204 caliber rifles in general.
My Savage 12VLP (a rock-stock out-of-the-box factory rifle) shoots the 39 gr. Sierras very accurately (and also shoots the 32 gr. V-Max, 32 gr. Sierra, 35 gr. Berger FB HP, and 40 gr. Berger LTB accurately as well). Does the target pictured below look like the .204 caliber rifle can't shoot the 39 gr. Sierra bullets accurately???
The BC for that bullet is .283!!! After looking at the target below, please read the paragraph below this target and then check the numbers in the chart I put together below that paragraph for some wind deflection and drop numbers. (I was shooting the faster load with the 39 gr. Sierra using H4895, but switched to Rel 10X and a slightly slower muzzle velocity because the Rel 10X is giving me lower ES and SD numbers and slightly smaller groups.)
Another quote from you: Quote:
I to have looked at the ballistics of both. A couple things come to mind. First most of the factory .204's with a 1-12 twist are not shooting the 40 grains as accurate as the 32 grains. So you gain drift but, lose accuracy. Reloaders are using bullets somewhere in-between. Most .204 shooters are using the 32 grain because of this.
I know that I have read where some .204 shooters can't get the 40 gr. bullets to shoot accurately, but I have also read plenty of reports that stated some .204 shooters get better accuracy from the 40 gr. bullets than from the 32 gr. bullets. Have you come across some research study that verifies your statement in the quote above? If so, let's have the link to the information so we can read the report. I will have to add here, that I got the 40 gr. Berger LTB to shoot very accurately at high velocities, but couldn't get the 40 gr. V-Max to shoot accurately at high velocities. It shot fine below 3,800 fps, however, would give your 55 gr. bullets lots of competition in the wind deflection and accuracy department.
You also state: Quote:
The .32 grain does not have as effeciant a BC as the 55 grain 250 does which is the most common 22-250 round. Energy..........ditto.
Also "foot pounds of energy" does not factor in momentum which favors the heavier bullet and is real.
While I agree that the lighter 32 gr. .204 caliber projectiles do not have as high a BC as the 55 gr. .224 caliber bullets, once again, let's compare the heavier 55 gr. in the .224 to a heavier 39 gr. bullet in the .204 to make the comparison more more realistic. You state wind deflection is less with the 55 gr. projectile in the 22-250. Here are numbers generated by a ballistics program that prove that the 39 gr. Sierra has better, not by a big bunch, but better wind deflection numbers than your vaunted 55 gr. and 50 gr. bullets in the 22-250. Please note that I selected 55 and 50 gr. bullets with about the highest BC I could find for the .224 caliber. If you shoot 55 gr. Hornadys, then your BC will be waaaay lower and your wind deflection and drop numbers will suffer a great deal.
Well, I have wasted enough time on this topic. Those who want to learn will read and take note and those who don't want to be confused by the facts will stick to their guns. /ubbthreads/images/graemlins/grinning-smiley-006.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grinning-smiley-006.gif As for me, I am more apt to grab for the .204 Ruger than the 22-250. One thing behind that selection is that I like the fact that I can see my hits in the scope with the .204 and that usually isn't possible with the 22-250.
