Faster twist rates do well with heavier bullets...Thank you for all the good info. I think i will order the new version for Lyman book.
One thing I notice on bullet box was the twist rate. This bullet is for a barrow that is 1-12. My remington is 1-8 does that really matter?
Slower twists do well with lighter bullets at higher velocities..
Previous poster brought up flat base vs boat tail..
Most rifles will shoot a flat base bullet better than they will a boat tail..
Reason is simple.
When bullet exits the bore? The flat base is "out".
The boat tail is subject to any gas that comes by an "imperfect" crown and may start to "yaw".
Another thing about boat tails...is....the boat tail formed well? Or? Does it have a defect? (a bad lot of bullets can make a good rifle shoot poorly)..
Realistically? A good bore with a decent crown?
You will not notice the difference until you get to the 600yd line....
View this as a "journey"....
Get a "diary"...keep a record of each shot fired. Weather. Overcast? Clear? Range face North? If not? What time?
How did you "feel"?
The better the log you keep? The easier it is to duplicate good loads...and avoid loading ammo you don't like...again! LOL
