All these posts are confusing (to me), so I re-read
Ckgworks posts to try to figure what he was saying/asking.
Post-#1:
He has a Remington 600 that was a "king" in it's day. He modified the barrel and added a youth stock, but it's not doing what he wants it to do. He wants modern-day performance out of has-been modified rifle. (Ever try to make a cat bark, or a dog meow?)
He answered his own question of performance with a 6.5 Grendel, which has ballistics that rival a 243, without the recoil...a 'youth' caliber to be sure!
And then he asked us guys on how to go about on salvaging a poor performing rifle.
Simple answer is...if you want a modern-day performing rifle, you need a modern-day rifle. The cost to bring a has-been rifle up to modern-day standards would be a financial nightmare, but some to it anyway. (Ever restore an antique car to brand new status? Ouch, right?)
Post-#21:
His key statement here is "more coyotes get shot than deer"...he wants a coyote rifle...first...then a deer rifle second.
One of the best coyote calibers of modern-day is the 6.5 Grendel! And it will handle the occasional deer, as he has already tested and approved.
He has subconsciously answered his own question and didn't even know it!
The 6.5 Grendel.
Post-#28:
He wants a rifle for..."10 year old....especially a girl with their muscle structure."
Again...he has subconsciously answered his own question and didn't even know it!
The 6.5 Grendel.
Post-#30/#33:
He's explaining (again, but no need to) his initial reason for staring this thread.
Post-#44/#45:
Off track explaining "his" rifle of choice, not the choice he wants for his daughter, but makes for good conversation.
Post-#50:
Explaining how he teaches his children his rifle/hunting philosophy...good words! And again he mentions the 6.5 Grendel...
Anybody see a connection here?
