[Double Trouble]

I was planning on using RST spreader loads in my Parker for grouse this year.

In an effort to get a wide pattern, I fear that using too large a pellet will lessen my pattern density. As a result, I've certainly rules out # 6 shot. However, is # 8 too small for grouse ?

Please let me know of your experiences with # 8 vs. # 7 1/2.

Thanks !
