The rifle in question is a custom 98 Mauser in 30-06 Ack Improved. It is an accurate rifle, but the throat seems to be a short standard length or a bit shorter. Reluctant to do too much in the way of long throating its chamber-but... Wonder if Dave Manson could rig up a long throat T-handled chamber finishing reamer?It would'nt take much. Ideas? Avatar | ||

Unless there is a compelling reason to lengthen the throat, I would be inclined to leave it alone. If the existing throat requires you to seat your preferred bullet too deeply, and that really bugs you, you can lengthen the throat, with a throating reamer, in the lathe. Regards, Bill | |||

No, Dave Manson can't make you a throater; He no longer owns the company. Manson Reamers can certainly make a throater, as does PTG and Clymer, as a standard item. | |||

The issue is twofold: The 30-06 AI favors heavy bullets and slow powders like H 4350, RL 22 or IMR 4350. Heavy bullets take up more powder space. A short throat compounds the problem as to bullet ogive, usable powder space combined with bullet seating depth. Some heavy bullets like the early 225 gr Barnes bullets had long sloping sides and a forgiving slow ogive.They work well. Others bullets will not allow shallow seating before contacting the lands. Unacceptable for best performance handloads with heavy bullets. Avatar | |||

I think you have to look at how much juice you will get for the squeeze. The 30-06 even in the AI version is not going to push a 200 grain bullet much beyonf 2700 and a 225 grain much beyond 2550. So what are you really giving up. I bet if you run some JBM ballistics calculations you will find the 50-75 fps is going to make no difference at all in your effective range. Given your interested very heavy for caliber bullets, I suspect you aren't going to be using this riflw for 350 yard plus shots. So now the 50-75 fps becomes even more immaterial. Mike Legistine actu? Quid scripsi? 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. | |||

And another factor is the length of your magazine box. | |||

Already factored in the magazine box. A 1981 Handloader magazine article featured the 30-06 AI with more modern powders. Extruded powders are more promising than spherical like H 450. But the 4350-MRP-4831 will get the nod for heavier bullets. Already have a supply of Swift 180s, Nosler and Hawk 200 gr RN and partitions. And a boat full of cup& cores... The idea with loading goals is to duplicate 300 H&H velocities with a more efficient case. With that goal in mind, it has been achieved with a successfully accurate Mauser. Think it best to leave it alone-and use it in the inter-mountain west. Avatar | |||

The 30/06 AI will not duplicate 300 H&H performance. It will beat standard '06 performance by about 3% (tops), assuming both cartridges are loaded to the same pressure. Regards, Bill | |||

I have found with my 30-06 Ak IMP to get a good bit more speed with both 180 & 165 grn bullets safely than when it was a standard 06. I did put another tube on it, and went from a 22" to a 23.5" bbl. The Nosler # 4 manual has some good load data for the improved version. Hang on TITE !! | |||

there's no replacement for displacement - no 30-06 at realistic pressures is going to come close to heavies in a 300 HH ... in the same caliber, at the same pressure, you can expect 1/4 of the % increase of capacity in velocity - If it shoots good, and you want 25-35 FPS at the risk of ruining the accuracy, it's your rifle. opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

How about a manual reamer? I've never used one. So, I ask. would the current throat keep the cutter true and do an accurate job? ONE EXAMPLE Life itself is a gift. Live it up if you can. | |||
