Yeah now its time to go back to powder loads and test again. Seems like this rifle likes 73 grains of RL22 the best but 74 grains tested good as well. I also need to test 75 grains and the 180 grain Accubond bullet a little more now that things are settled down.

We'll the problem is solved fella's. Tightened up my scope rings with 1-2 turns as noted earlier in my post. Also switched to CCI magnum primers. Kept the COL to 3.340. Went to the range this morning at shot 1/2-1 inch groups at 100 yards with several holes touching. Thanks for the help. I might...
Alright knowing that the Hornady OAL gauage is showing 3.573 for me to seat to the lands of this gun (probably won't work in magazine) and my current loads are 3.340 what starting point should I use for bullet seating??? BTW at 3.573 the bullet is well below the throat of the case when seated...
Dougb - No shake at all when dry firing. Smooth as glass.
1858 - ahhh...the screws on the scope rings seemed to be a bit loose. I turned them 1-2 full turns per ring screw. They will not move now. Whould this cause the spread in groups???

Hillbillydelux - I may try some CCI primers and set the length at 3.450 just to give that a try. I have been trying different powder loads and the best groups are at 73 grain. Anything north or south of 73 grains seems to start spreading out with some flyer's.

Doug b - Interesting. We noticed that on the primers the firing pin appears to be hitting hard. They are not mushroomed or flat....just appears to be a hard hit.
What did you do to resolve the problem?

300 Winchester Magum guru's I need some help. I have been shooting my Remington model 700 - 300 Win Mag at the range after trying some different powder loads. I'm getting 2.5 -3" groups at 100 yards. I know that I can do better. My cartridge length with the 180 grain Accubond bullet is at the...
Found some information about this on the RCBS site FAQ section....Looks like the seater plug does not properly fit the bullet I am using. This looks like the issue which is causing the scratch rings around the bullet. I may have to call them to get a custom die made.
Here is the link...
I just got done reloading my first batch of 300 win mag cartridges for testing. I was using a new RCBS seating die and noticed there were small surface scratches all the way around the bullet in a circular pattern after the bullet was seated. I tried to clean the die out however they still...
Thanks for the help guys. I will begin with my test loads this week. I plan on using RL22 and the 180 grain Nosler Accubond bullet. Max load in the Nosler Manual looks like 75.5. I plan on starting at 72 grains and working my way up from there. Does this sound right or should I go a bit...
I just bought a Remington 700 CDL in 300 Winchester Magnum. For reloading I bought the Hornady OAL guage to help assist with OAL for this particular rifle. I'm using the guage as instructed with 180 grain Nosler Accubond bullets. I keep getting readings of 3.571 OAL when measuring from bottom of...
