I was sold a rifle and told its favorite load was 57g of IMR 4350 with a 165g Hornady Interlock Flat Base. Ive been waiting forever for the flat bases with no luck so I caved and got the BTSP. I plan on working up to 57g, if it ends up being necessary, we will see.

Who else loads this, and your thoughts please, as well as your data if you dont mind. Cheers!

Rifle is a M1917 in a bedded sporter stock topped with a classy older Leupold. Really nicely done rifle.
 
I am shooting in my Parker hale

Fed brass
Hornady interlock 165g BTSP
CCI 250
H4350 @57g
COL I have to confirm when I get home.

I have some loaded with IMR4350 to see if I can cross over. As I have a much bigger supply of the IMR.

Gun shoots just under a inch on a good day.
Have good performance on black bear and deer
 
i use imr 4350 cci 250 primers @ 59grns with 165 and 57 grns with 180's. 22 inch barrel. no issues at all. both loads have been uses in a few different 30 06 rifles the 180's at 2800 fps can't remember veocity on the 165's.
 
Most 30-06 rifles will handle 58/59 grains of IMR 4350 behind the 165 grain Hornady FB, with velocities in the 2900+ area. [24" barrel]

I have 3 - 30-06 rifles at present, 2 Remington 700's and a Vanguard. All have 24" tubes on them.

I am shooting a similar load in all 3......58 grains of 47N [slightly faster than IMR 4350] and the 165 Partition. This load flirts with 3000 in
one Remington, 2945 in the other Remington and 2970 in the Vanguard. All shoot sub-moa. Brass life is excellent, primer pockets stay snug.

I don't normally use 4350 with 180 grain bullets in my 30-06's. Much prefer IMR 4831, Norma MRP or Reloder 19 and 22.
I expect around 2850 with a 180 and one of these powders in a 24" barrelled 30-06.

Regards, Dave.

This guy knows what he's talking about!!
 
A top quality barrel will do very well with a boat tailed bullet.

A mediocre barrel will shoot a flat based bullet better than a match boat tail. That may be what you were being told.

For other than match quality barrels flat base is better than boattail.

For all barrels, a soft point or HP is better than FMJ.

For many rifles I have had great accuracy out of plinker loads made using the Sierra 125 gr Soft Point (308) and the Hornady 150 gr pointed Soft point.

If a barrel is in poor shape, I use the round nose flat base bullets.
 
i am using a max load of RL22 and 180 accubonds seated just off the lands and its very accurate - 5 shot one hole groups at 100 metres on my good days. Thats with a FN M70 super grade. I tried H4350 with pour results, but thats just the same as all the other H powders i tried.
 
Thank you all.

I went out to the range today for the first time with my reloads. Im having an extremely hard time finding info on Hornady INTERLOCK 165g BTSP. So I decided to start with what the previous owner had told me. fav load at 57g, but start a bit low.

I decided to go with 54.5 up to 57 in .5 grain increments.

I had the rifle on a home made full size rest.

I also tried to let the barrel cool down between volleys as it was getting quite hot. I was doing 5 shot groups @ 100. Im not really sure what to make of the results, some input is appreciated. Seems like I had some flyers? I may add more info, im tired now and going to bed. Cheers!

Oh, and this may be a silly question, but with the lead at the tip not always being the same, how do you measure a constant COL?

I would try 58 grains. There are reloading books that show max loads higher than 57 for IMR 4350 and a 165 grain bullet. I use 58.3 grains of H4350 and a 165 in 2 '06s I have.
 
From the test, im getting the thought that the 55g was better than the 56 and 57, getting worse as it got higher. the load was created with flat base bullets, im using boat tail, how much of a difference can that make in what he told me the fav. load was? and, although i was taking breaks, i still shot 30 rounds. 57g being the last. how much would that of opened up the groups? and, im thinking of starting with the higher load next time to see if that was the case. Cheers.
 
From the results of your test, there is no difference in accuracy in any of the loads shown.
Also, measuring COAL is a useless part of reloading. Just seat them so the bolt will close without excess effort.
But hey man, this is the internet and you are making one hole groups!
 
Totally disagree. With all my years of reloading for many different hunting and milsurp rifles, measuring and adjusting the COAL does benefit the accuracy of many of my rifles. Can you try to explain how its a useless part of reloading ? Granted, if you just want your gun to go bang, don't bother reloading , go buy your ammo and quit wasting your time. Even companies like Hornady will recommend offsets for your COAL to get the best out of your round.

how long are you letting it cool between groups?

what type of rest are you using?

I'd give a heavier bullet a try as well.

COAL means the total length of the cartridge and the distance off the lands will vary considerably, even on bullet to bullet out of the same box.
Plus, when you are shooting 2 1/2 to 3 inch groups, the last thing to worry abut is how deeply the bullet is seated.

There's too many variables to answer your above questions. It might be that the bullet you are using just won't shoot good in your rifle. Keep shooting and start with a clean barrel each time you go to the range to keep that consistent.
 
I loaded up a bunch of 165 grain nosler partition with H4350
I tried loads from 55-58 grains and went with 58 I was getting right around a inch (I was getting more around 5/8" with 55 grain)
I went with the hotter load and increased velocity It's running just over 2800 fps the moose I shot didn't even take a step
