MT325wsm kimber
i just got a new Kimber Montana in 325wsm i have been working up a load and i have found a load that groups good but it is not close to the max load. When i move any closer to the max the group opens up.should i just leave it.

MTI have used 3 different bullets starting at min and work up to max. the only load that grouped under 1 inch is 64grn 760 win with 200 tsx and 215mag large rifle primers. i am new to reloading so i have only used the win 760 and 215 mlr. Im moving to Alaska in Feb and try to get this worked out before i leave.

Mike_DettorreI would try H4350...always been a very accurate powder for me.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.
What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

crashcarruthersTry plain large rifle primers. Most of my WSM shoot a tighter group with a large rifle primers, than mag. primers.

djpaintlesHere's 4 loads including a factory load that worked well in mine:
I used Winchester brass and Federal GM215M primers in all the loads........................DJ

MTfor a hunting rifle will a 150 fps make any noticeable difference right now it seems my groups are improving as long as i don't go over 64grn of 760 and stick with TSX's. When i frist got the rifle i started with Accubonds and could not get under 3 inches was very worried with what i had read about the kimber rep but the more i shoot it the more i like it at around 125 rounds its looks promising. Thanks to all that have replied

Nordic2Have you tryed bullets with a different shape? Maybe like Norma oryx 200g, or a 220g bullet.
28 November 2009, 21:28
MileHighShooterAre you trying different powders, or just different bullets with the same powder? I see good results around here with RL powders, 17 and 19.
28 November 2009, 23:01
MTi have only tried one powder and getting good groups just not at the fps i would like. i will give the IMR 4831 . what do you all do with components that you are not getting the results you were looking for. i have just been firing it to get more rounds though the barrel but it seems to be a wast of money.
