I am looking for any data that uses 4320 and a 220 grain roundnose, this is for a 30/06. This is for a bush gun, max yardage would be 150 yards, i have some 150 grain boatails loaded for long range shooting.
I bought 30.06 factory Remington loads Core-Lok 125,150, 165, 180 and 220 grains. I have shot all of these and cannot tell the difference in recoil.The 220's in the '06 are serious medicine. The SD is higher than that of the 6.5mm 160gr bullets. (.331 vs .328) For the most part, the 220's are toughly constructed and won't give any benifit on game under 500lbs. On deer with typical shots, they'll not expand sufficiently and act like FMJ's. One exception is the Nosler Partition. The nose section of the Nosler will expand readily. But, for this reason, it seldom penetrates anymore than the 180's. It will make a mess of a deer on a length-wise shot, however...
My MkX Mauser shot up a bunch of Norma 220's back in the mid '70s because I bought them at a hardware store going out of business still have an empty box with a $3.00 sticker on it. I would bet aquaintances that my '06 kicked more than their 7mm Magnums. I'd then let them touch off one of those Norma's in that '06 w/o a recoil pad. None wanted to shoot it a second time. I learned what a Weatherby eye was from the Leupold scope I had on it too....... And danged, if they werent accurate too ! Never shot a deer with one, though.....
If I was loading 220's, I'd want to run them about 2,400fps to get decent accuracy, but less than the near 2,600fps they're capable of being run to limit the recoil... I'm not recoil shy, (I've got a .300RUM, too) but, I don't like getting unecessarily beat up either.

That's ok I don't want to beef up anything that will kill the shoulder even more. I thought the 125 grain 30.06 Remington Core-Lok would have the least amount of recoil but I tried them all and they are all the same.depends on rifling twist rates, i have different twist rates in my savage, its calls for 165 grain and lower for accuracy, my interarms and 740 love 165 and up for accuracy. the factory laods have same recoil due to less powder for the 220 when you handload you can beef that 220 up few grains and kill your shoulder in no time.
What would be the most accurrate between the 125, 150, 165, 180 and 220 grain Rem. Core Loks?it depends on application, im going to run a ballistics to give a general idea of trajectory, but im theorising that the 220 grain will have a trajectory similiar to the 30/30, which is ok if you are using the rifle for a bush gun.
So if you aren't going to shoot further than 100 yards the 220 grain 30.06 bullet will be the most damaging over the lighter loads. Accuracy won't be affected as long as it's sighted in correctly.alright sighted in at 100 yards the 220 grain drops 23 inches at 300 yards and 52 inches at 400 yards. this is a sierra 220 grain at 2300 fps
the 150 grain drops 13 inches at 300 yards and 30 inches at 400 yards sighted in at 100 yards and 2900 fps
for short ranges the 220 would pack a massive punch but for long range pronghorn or mule deer shooting id use a 150 or 125 grain ballistic tipped boat tail.
I'm not sure what the twist rate is on a Baretta Tikka 3 Light 30.06 rifle.accuracy would be effected, 30/06 rifling varies some have 1in10 twist others can have a 1in12 twist, the twist effects accuracy different weights prefer different twists to stabilize the bullet in flight better. 220 grain bullets prefer a slower twist such as 1 in 10 but 125 grains and 150 grains prefer faster twist rates such as 1 in 12. Even this is what benchrest guys do to gain an edge of accuracy, and in truth the difference in using a 220 grain bullet with wrong twist rate wont be noticed because you wont be shooting over 300 yards ideally.
I like IMR 4350 which is listed.
Would that be medium weight like 165 grains or 180 grains?look it up on google my PDF is not working on this computer so i can not view the twist rates but it appears your rifle may be a 1in11 which would prefer medium weight bullets
• Rates of Twist: 8”, 9.5”, 10”, 11”, and 14”look it up on google my PDF is not working on this computer so i can not view the twist rates but it appears your rifle may be a 1in11 which would prefer medium weight bullets
