True. Rifles have to be very simillar, and will still need to develope of the rifle. I only have two Brands/Models of bolt action. Win M70 Classic Stainless and WBY MKV. I have occasionally used loads from my friends with same brand/model/caliber for starting loads, but not before checking...
JD338, my personal experience, if the rifles are same maker and model, it would be pretty close. I have 3 WBY MKV 300, one Japenese Deluxe and 2 US Accumark. All three shoot 200 AB or 200 PT to 300 yards, same load, very close. I could fine tune more, but no need for their intended purpose.
I load that in my 300WBY, two rifles, 200 AB or 200 PT, RL 22, same load. Took them to Africa, had great success. I need to try in in my M70 300WM and 300WBY
Oops, they had primiers, Federal and CCI, but I did not check what they were exactly. Anywhere between $9/100 and and $12/100 with 200 primer limit. My other LGS sent emails they have primers, but I never stopped in to check prices.
I gave a Japanese MK V Deluxe to my son and he loves it. Its a great shooter. For more information on it, you can write directly to Weatherby, The are very good about responding.
For values, you might get more information on the weatherbynation website, but I value Dr. Vette's opinions a lot...
I have enough for hunting for me and my kids for a few years. I stop shooting other than 22LR. I tell my friends, I will provide the firearms and loaction to shoot if the bring their ammo.
