Reloading For 7mm Rem Mag

[markg]

I recently purchased a tikka t3 in 7mm remmington magnum and I will be reloading for it. I did a few searches on the topic on the forum but didnt find any info. Ill bet there are several threads about the topic i cant find.

That being said, any suggestions? I plan on starting with imr 4350 with the nosler accubond long range 150 grain. Noslers manual says that 63 grs of imr 4350 was the most accurate load of that powder and it produced the highest Velocity.
I have some IMR 4831 , H4831 SC and some imr 7828 and was currious if those are better starting points.

Your advice is always appreciated.

I should note that I am hoping to get 3100 to 3200 fps out of the load if i can.

Those numbers are for their gun and conditions. Yours may be totally different.
Secondly 63 is their max load. DO NOT START THERE. Just because it is safe for them, don't assume it is safe in yours. They list a minimum. Start there. Work up slowly.
Next, if you are chasing accuracy, and by the bullet choice I am assuming that LR accuracy is your end strategy, don't get all hot and bothered with the speed. At the end of the day if you are shooting over 400 yards you are cranking dials. Does it really matter if it is 38 clicks or 41 to hit a 500 yard target? Chase the accuracy first. If speed follows safely then that's a bonus of sorts.
Last, many, many 7 Rem Mags seem to really love the 4831 powders. Again yours may not but they seem to really like each other.

Thanks Cowtown. That was exactly what i was looking for. I have been reloading lighter calibre's for several years. I hate recoil, but i bought a 7mm and put a muzzle brake on it because i have some friends that have access to some land with moose and elk.

I have had the best results in my rifles with R-22, but it is so hard to get, that it isn't worth considering. The second best powder in my rifles was IMR7828, with IMR 4350 close behind. I pay very little attention to the so called most "accurate load",as they have rarely been the most accurate in my rifles. I did some testing with the 150gr Accubond LR in two rifles, but accuracy was disappointing in those rifles. Both rifles did much better with the 140gr Accubond. I find that I am usually able to reach around 3100fps with a 150gr bullets in the 7mmremmag, and 3200fps with the 140gr bullets.

Try 63 grains of H4350 and a150 Ballistic tip. This has been my accuracy test load for all the seven mag I have owned. Seldom fails to impress

One thing that I have learned over the years, is that the make and model of firearm often means little. I have seen rifles of the same make and model, that were only a few serial numbers apart, prefer very different loads. That is what makes handloading such a challenge.

It's hard to understand why but every rifle is unique they use the same materials ext but each has a personality of its own.
