I want to buy the Remington model 7 Predator . 22"magnum contour bbl. So what has the most potential for accuracy 22-250 or 243
Worker:
In my experience of owning rifles and reloading both 22-250 and .243 in the past 25 years or so, the 22-250 is my choice for most potential for accuracy.
Others results may differ.
With Lapua cases available for .243 - and - Norma cases available for 22-250, reloading using Lapua cases may be the choice of many, but Norma cases are also of superior quality in my humble opinion.
I personally prefer slower burning powders for accuracy at a good velocity with barrel length at 26". If I were reloading for a Remington 7 Predator with a 20" barrel, a faster burning powder would be used.
