17 Cal 30 grain bullet

[uncle buck]

Notice on Midwayusa that one can get Berger 30 grain .17 Cal bullets...As you know factory rounds come in 20 grain V max and 25 grain HP..Now most of us use the 25 Grain HP and they work well...Was just thinking....I wonder how the 30 grainer would work for coyotes? .05 more grain probably would hit harder and penetrate deeper too... Could blow a big hole out the other side of the coyote too.   I am going to have to try this bullet on chucks.....Chucks are a good tool to use to see how the other side looks once you get them with the 17's?


Could be that the 30 grainer's might work better in the 17 Rem and not in the 17 Fireball???Since the 17 Rem case is a bit longer and can handle more powder...

Something about the little fireball case.. Look at the velocities in the Rem catalog.  Compare the 17 Rem and the 17 Fireball 20 and 25 grain factory bullet data... The fireball even though it's a lot smaller case.  Almost equals the larger 17 Rem velocities and other data too...Unbelievable.

I was talking with my gunsmith today and asked him about the 30 grainer's... He said you have to make sure the rate of twist is just right to stabilize the bigger bullets...I have been trying to find out the length of this bullet since I have a formula that I use to see if the rate of twist will work for any given bullet.

(1.)  Measure the Length of a bullet in inches, then divide by the bullet diameter.

(2.)  Divide 180 by the result  of (1).  (note the 180 value will always be a constant in your calculations for all computations)

(3.)  Multiply the results of (2.) times bullets diameter.  Round to the highest whole number for your rate of twist..


Here is one I just used to figure if my Encore 22250 with a rate of 1-12 will shoot Nosler 60 grain Partion bullets:


(1.)  .752 divided by  .224  =  3.35

(2.)  180 divide by 3.35  =     53.73

(3.)  53.73 X .224   =  12.03  

So my Encore 22250 with a rate of twist of 1-12 should shoot the .224 60 grain Partiton well.


Formula Found in April 2010 Guns Magazine

Uncle Bucky...I give my gunsmith the bullets (projectile only) for the one's I want to shoot and he tells me how long I should make the cartridges based on measuring my lands / chamber / or something.

Good info Seeking Coyotes !!!I never thought about that before...If you take your gun into a gunsmith to get it worked on..Gee I'd give him a few more bucks if he could take the measurements based on all the bullets I shoot.. Gunsmith would have all the equipment needed to check just where the rifling starts for ones gun...

That tool is fairly inexpensive, its called a bullet comparator

This trick really worked for my .243.  I was going nuts trying to get sub moa 5 shot groups on some Berger 95 grain VLD's in 6mm.  I was shocked at how long my gunsmith told me that my coa should be.  I loaded em to his measurements and now have sub moa 100 yard 5 shot groups from the Savage Weather Warrior.
