hey, first post,

i have a ruger 10/22 and was interested in this 17hmr round stuff.

what is the purpose of this round?
is it more expensive?
how can i be able to shoot this round?


also, i was looking at the new springfield xd .45  what is the difference between .45acp and .45gap

thanks guy

Howdy and welcome to the forum,

The 17HMR is pretty much a 22 magnum case necked down to 17 caliber.  It offers a higher velocity and a flatter trajectory than the 22 magnum by sacrificing bullet weight and energy.  It is a inherently accurate cartridge in the many rifles it is offered in.  I don't hunt with mine, but it is often used for hunting small varmints such as prairie dogs.  It is more expensive than .22LR.  I pay about $10 for a box of 50.  If you want to shoot this round I would recommend just buying a new rifle.  There are some people here www.rimfirecentral.com who have made extensive modifications to a 10/22 so it could shoot the longer magnum rounds.  You can also buy a conversion that will allow your 10/22 to shoot the 17HM2 round.  It shorter than the 17HMR, being a .22 stinger length case necked to 17 caliber.  Hope this helps

The 17hmr is a good round depending on what you are using it for.  I wouldn't buy it just for a casual plinker.  I use mine for groundhogs and squirrel hunting once in a while-make head shots on squirrels.  I usually can buy 50 rounds for $8-9.  It is a very accurate round and flat shooting.  

thanks guys, i think ill stick to my plinker ammo!

meszues, 22Lr is great for plinking but the 17 HMR and 17 M2 shoot very tiny groups!  I love mine.
