help with a new caliber

I was thinking of these three calibers and cant decide. 6mm-284 243 Super Rockchucker, or a 6.5-284. I'm kinda leaning towards one of the 243 because i want a good varmint round but i do like the versatility of the 6.5 so i guess what my question should be what 243 round do you like better and then what round do you like best. thanks

6.5 works for varmints but do you plan on hunting anything that would require the heavier bullet if you are just hunting varmints 6mm would fine

Re: help with a new caliber

How far out do you realistically plan on shooting the little buggars?

Admired the 243 Rockchucker from a far. Love the 6.5-284. Never tried the 6-284, but bet it is a killer round, as I love its brother.

These are pretty hefty loads for strictly varmints, IMO, but really depends if you are looking at really LR shooting of these critters. How big are these "varmints" that you are planning to explode? I don't think that I would want to spend the entire day blasting away at a PD town with any of them myself

Go with the 243 Super Rockchucker. I have one and it is awlsome. I would go with a 1-9 twist so you can shoot the heavier bullets if you want. I have a 1-10 on mine and shoot the 90 grain Bergers at 3600fps. Can get 3700 but not as accurate in my gun. My neighbor also has one of these and has killed a groundhog out at 930 yards. I have not had the chance to really streach the legs out on mine yet with my farthest shot with it has been at 300yards. Only drawback is the price of the dies. I think they run about 140 bucks. But i think it is well worth it for this caliber its a real standout. If you got any questions about it just send me a PM.

I like the 6.5 284 because it is so accurate but speed is a consideration for the 6mm wildcats---more room for error on drift and elevation...

Re: help with a new caliber

I have the 243AI, 240 wby, 6mm-06 imp which I think is your super rock chucker and the 240 gibbs along with others. If you want performance the 240 gibbs is just awesome and will outperform the others in fps. It is just amazing for long range performance but with a lot of varmint shooting barrel wear becomes a factor. I narrow my two choices down to the gibbs and the 243 AI. The others are just in betweeners that fill the gaps and are not as fast as the gibbs but still have the barrel wear issues. So I drop down 200 fps to the 243 AI which has excellent barrel life and is one of the most accurate cartridges ever developed. When shooting varmints is there a huge difference between 3900 fps and 4100 fps when you get twice the barrel life or more out of the 3900 fps one. The 243 AI is just as inherently accurate as the 6.5-284.

With all considered if I were going to shoot it quite a bit I would build the 243 AI over any of the others because the many benefits of it outweigh the 200 fps to the gibbs. I think the 243 AI is the best overall all around 6mm cartridge. If I just wanted a high performance 6mm and that was the only criteria then I would do the 240 gibbs. Also the 264 gibbs will virtually duplicate the 264 win mag if you look at 6.5 rounds.
Predictions are difficult, especially when they involve the future
