I just bought some H1000, because of it's slower burn rate, as discussed by eldeguello. I've heard very good things about the Sierra 160gr spbt bullet, so I'll continue trying to make that bullet work. Maybe the H1000 will help.

I like my 175 GR. Horn. Rounds with RL 22. I get a consistant 1/2 Inch group out of my T/C Encore. @ 100 Yards.

Hunter338.

Try the new barnes tsx in the 130 grain with IMR 4831 it shoots awsome in my 7mm rem mag in a weatherby rifle Iam also looking into the 160 grain barnes tsx so far I like the IMR 4831 and 7828 but iam fairly new to reloading my self. Use the Barns X data for loads but start at the bottom.

shawn, I don't use seirra bullets personally but do know a few gents who do in 7mm rem mags, both use H1000 & 160gr seirras.

I have had goodresults with Imr7828 and RL22 in my 7mm rem mag for 160 gr Nosler bullets. For 150grNBT'sI havebeen usingImr4831 which shoots exceptional. This is my first year using 140 Gr Barnes TSX and RL22 shoots great!! I shot my first animal with the TSX just over a week ago, raghorn bull elk and received excellent performance. Not the biggest bull or toughest test but none the less a complete pass through of ribs with slightly quartering shot, severed lungs and dead elk approx 75 yards later. Blood trail wasn't required but I will say at the shot site it was small but within the first 10 yards or sowas evident and if I had to trackthis animal I would have no problems. I am not sure how it will work on a rib shot for a deer? I hope to find out this fall as I will not be switching this year like in the past.

As far as seating depth my noslers are .010-.015 off the lands. The Barnes are .030 off the lands. In my rifle the accuracy is slightly better the closer to the lands I get but I still want to remain safe and within pressures...these are basically as close as I'd seat them for the loads I am using.

Good Luck and be sure to let us know how your progressing/thoughts on the H1000.

i like hornady's 162gr spbt in front of reloader 22 (.5 grain BELOW max in lee man.) with a cci lr primer (not magnum). i get 5 shot groupsat 3/4 to 1/2 inch.
i also load a 100gr sierra hp in front of h4831sc 1.5 grain below max also with a cci primer.

i tried using magnum primers in the 7mag withdismal results. most people believe if its a mag round use a mag primer. this not really the case. you dont have to use a mag primer unless youare charging more than 70 grains (if im reading my manual right).

good luck to all this coming season.

I, like others have mentioned, like the IMR 7828 in my 7mm. In fact I use it for every bullet I load from 140 to 175. I'm working up a load for the 160 Accubond right now and at first blush, it looks good. The 140 Nosler Balistic Tip load I use averages .5" at 100 yards and velocity just under 3400fps. I do use a CCI mag primer due to the slow burn characteristics of 7828. Got such good results that I never felt the need to try a standard primer.

Good luck with yours.

Hello Shawn. Part 1. You have many things going on here and I need more info to help you. First, why are you loading such heavy bullets? Are you Elk hunting? Second, what grain bullet are the factory shells you shot such good groups with? Third, the reason you are having problems closing the bolt is not because you are jamming the bullet into the lands. The reason here is that a 7 Mag is a powerful belted magnum that requires full resizing after each shooting. The shoulders of your brass is being restricted in the chamber. Then the brass must be trimmed to 2.490. Try this with an empty and see how easy they chamber. My guess is that your OAL of 3.26 is not into the lands although that would explain the wild groups to some extent.

Part 2. My experience of 40 odd years monkeying with the big 7 has been filled with a mix of the agony of defeat and the thrill of victory. It wasn't until I became a serious reloader that the mystery was revealed. First, the 140 gr bullet is king in the big 7. When you consider the extremely long bullets available ie the Nosler Accubonds and BT's, these bullets are extremely accurate and efficient. The problem is when you get in the heavier bullets, they get so long and have to be seated so deep as to keep the bullet off the lands, they will not stabalize in many rifles. You are also in most cases compressing the powder which is not good for most powders. Second, you need an OAL gague. They are cheap and they take all the guesswork out of the equation.

Part 3. The OAL with a 140 gr Nosler BT is 3.370 in my Tikka. I have found this rifles likes to jump a bit and seat the bullet 45 thousandths off the lands which equates to an OAL of 3.325.I have used nearly every powder and bullet combination in the books and have settled on one. I use 70gr RL22 and push the bullet at 3160'/sec. Groups are very consistent 1/2 inch at 100, 1 3/4 at 200 and 3 1/4 at 400 yards. This is a deer load. If you want to hunt Elk, just stick a new accubond in there and you are set. The 140 gr Game Kings should work just as good....maybe better. I go with the Noslers as they have a better BC and I need a 400 yard gun. If you aren't shooting super long distances, the 140gr Sierra Pro Hunter is also a great bullet.

Part4. Safety. Never jam a bullet into the lands....very dangerous chamber pressures will happen. Don't compress the powder unless the receipe says it's ok.

I hope this helps you and wish you good luck with your rifle. Regards, Rick.

Best advice, go buy a reloading manual (Nosler is very good). Read it cover to cover.

Are you weighing every charge ? Are you mixing primers or powder lots ? Are you mixing up different brands of brass ? All these things can have a negative effect. I would also try seating the bullet in a little deeper ( off the lands ) and see how that helps first. In the end you may need to switch powders. My Sako loves IMR 4831 but hates IMR 4350, you need to expirement a bit more.

My pet load was RL19 (around 63g I think), Federal case, Federal Gold Match 215M primer, and a 160g Accubond. Velocity is over 3,000 fps and for the deer and elk hunting I do that's good enough. I don't have a chrono so I can only go off the Nosler manual or some ballistics programs I've found on the web as far as performance. I've shoot paper out to 300 yd and they seem to be about where they are supposed to be.

I'm currenlty switching over to IMR 4831 just to see if accuracy is better or worse. With RL19 I was getting around 0.8" 5-shot groups at 100 yards. Plenty good enough but as a handloader it's always fun trying new stuff. Like they said, make sure to get the bullet OFF the lands by at least 0.010" to 0.030". Never seat the bullet so long that it touches, very unsafe unless you really know what you're doing.
