Home Forums Reloading Big Game Rifles Tikka 300 wm

I just purchased an Tikka 300 wm T3 and going to be loading Barnes 175 LRX. I understand the magazine only limits to 3.340" which puts the bullet .250" off the land ( long throat ). What powder are most of you using when loading for these tikka's? Bullet shoved deep in the case takes up so much room.

H1000

My 300WM loved RL-22 with the 168 TTSX and Fed. 215 primers. I’m sure it would do well with the 175gr. LRX. H1000 isn’t a bad choice either!

Thanks guys. I have lots of powders to work with but these tikka rifles don't give any case volume room. Seating bullets deep to fit magazine. I'm asking if any tikka users what type do?

Seating bullets to factory length really doesn’t crush the powder kernels as much as people believe. Yes a few get crushed but it’s such a very small percentage of the overall charge that it doesn’t affect the burn rate of the powder! Don’t let a few crushed kernels change your powder decision and end up with a less than optimal load!

Shoot straight!

Thanks, I'll give it a shot and see what happens.

I'm using IMR4350 and 180gr TTSX in my T3 300WM. 3100fps and itty bitty groups

OD- thanks for the input. Might try it next if H4831 doesn't work.

I loaded up some H4831SC from 73.0-74.0 grs guessing a lower node. 73.0 grs shot 1 1/4" group, 73.5- 1 3/4" group, and 74grs was 3" group. I might load up some 75grs. thinking 74grs is my scatter node. I know I'm cutting corners with reloading. Trying to find a decent load for upcoming hunt.

Okay so I loaded up some rounds and looks like H4831SC or RL22 looks promising. Both loads around 3/4 MOA @ 100 yards, and will work just fine. Thanks for all the advise.

anything slower than H4350.......

VV N560...........got any ??

No, I don't have any VV N560. These 175 LRX are .250" off the lands loaded at magazine length.

Mountain Tactical( Tikka Shooters ) sells a bottom metal conversion that accepts AI 300 wm magazines. It will gives you an oal load length of 3.600 plus a few thousands.

You might try RL23

Holy smokes, the Mountain Tactical bottom metal is pricey. Sawdoctor, thanks for the option though.

I found a good load using 75.2 grs H4831SC. Getting consistent .7's groups at 100 yards and will work for this deer season. Average speed is 2910 fps with the 175 LRX's. I'll fine tune it on off season.

Thank for the help!

I use a Tikka in 300wm for competition. Rl-22 if bullet is under 200gn, H-1000 if bullet is over 200gn.

These both apply to 3.34" col as well as 3.6++" col.
