Just finished my new hunting rifel a 7MM WSM
Using a Remington 40X single shot action and a douglas XX stainless Blank.
The first group fired was .347 with Winchester Supreme 140 gr Ballistic Silver Tips.
This was for break in and now I am ready to start reloading.
Any tips on Bullets,Powder,Primer&Brass
for this Cartridge would be great.
