I am having a difficult time working up a load for 300gr SMK in a Savage 110BA. I am changing powder to H-1000. Does anybody have any good loads?? I am using Lapua brass, Fed 215, and starting .025 off lands. RL-19 showed pressure signs without any good results, testing them @ 300yds. Need help!
 
Re: 300gr smk load info

Good to now. How much is your brass streching? With the RL-19 my brass was streching .016 to .020 each time... seems like it is a little much to strech that far.

That's WAY too much case working. You must have sized the cases down using a "small base" die or something similar. In both my semi auto LMT rifle and my bolt action TRG, the brass only grows .002 to .006", depending upon location (base of case, case just beow shoulder, neck, and headspace).

.016" to .020" is nuts. Something's way wrong.

I was using a RCBS shellholder #14, but have switched to a number #48 and it seems to be a much better fit. I am hoping this will solve my problem with that. Thank you for the info!!
 
Re: 300gr smk load info

Have you tried ramshot magnum? It works excellent in mine. Will easily push em out to 1k or longer. I load 89 grains 3.680" lapua brass 215 m . Not very good velocity but the accuracy node is there. According to jbm I will still be supersonic @ 1k and I'm only pushing them 2520 fps
 
Re: 300gr smk load info

Start at 100.... shoot about 5 times and see how they are grouping. If they aren't popping atleast 3/4 moa, I would pack it up. The .338 Lapua is just too darn expensive to be plinking. If they are hitting "same hole" groups, get your chronograph (if you got one), let your barrel cool down then shoot a few and see what your average velocity, sd, high, low, ect... is. People laugh at me but I have a program on my iphone called Ballistic:Field Tactical Edition that is AWSOME! Or you can get on line and go to the jbm computer and put in your data and enter your altitude, temp, velocity,...ect.... Once you have your data go to 200, record groups, then move to 300 ect... But in the overall scoop of things, I have found that If you are putting them in the same hole at 100 yards, you should be good to go out to 1k if you have your "ducks in a row" so to speak. If you have an iphone, I strongly recommend that app I was talking about. It makes everything so much simpler. Good Luck. Let me know how it works out for you
 
Re: 300gr smk load info

Oh yeah, there is also another app called istrelok that works excellent too. It isn't as in depth as the one mentioned above but it works pretty good too. And it's free, or atleast was
 
Re: 300gr smk load info

Not to question your responce, but is 100 yds enough time for a 300gr. smk to stablize and get into a tight spin. The only reason I ask is I had an other person tell me that it is similar to when you spin a top, it wabbles a little at first and then it pulls itself into a tight spin.
 
Re: 300gr smk load info

I think your buddy is spot on. But If your still supersonic at 1k, I don't think the bullet should be tumbling. Mind you I may be wrong, I guess I start at 100 bc 1) it builds confidence 2) it will somewhat predict performance at longer ranges. Also the $ factor is another issue. I love my .338 but it will drain your pockets. One thing I have learned is that velocity isn't everything. I'm only at 2515 +~ but will still be supersonic at 1k. You will drive yourself crazy trying to find that special recipe. In a nutshell, find your accuracy node, chrony it, if the numbers look good and it performs well stick with it. Try not to over analyze because it will literally be all you think about. Just read my quote. I hope you don't think I'm preaching & I most certainly don't know nearly what alot of these other guys do. I just love to shoot and help other folks out when I can. Good luck
 
Re: 300gr smk load info

Thats a great idea. I love the idea about building confidence at a shorter range, because the Lapua is very expensive to shoot. I have been reloading for some time now and this is by far the most difficult caliber for me to find a load that works well. I will be going out this afternoon with about four different loads with H1000 powder starting @ 87grs. and working my way up. I will keep you posted on the results. Thank you again for the insight and giving me a different appoarch to working with this caliber.

Re: 300gr smk load info

Just shot a .568 center to center group @ 200 yds. 87.0 grs. H1000. Moved up in powder 1.5 grs. at a time started to get pressure signs at 90.0 grs. Will reload five more and verify it again and maybe pull it in a little tighter. Thanks again!!

Re: 300gr smk load info

The BA must like 87.0 grs charge. Just shot an awesome three shot group @ 200 yds. .568 c-to-c, .020" off lands. Thanks for the load data!!

Re: 300gr smk load info

Daxter, went to range this afternoon and shot a 3.75" group at 520 yds. Calculated it and I am .72 moa. Pretty fired up considering all my "big scopes were on other weapons. Was using s mark IV 4.5x14x50 lrm1. Had to use my vortex pst to see where I was hitting on ar 500. No fliers. Just satisfaction.
 
Re: 300gr smk load info

Aimsmall,
Nice shooting!! I have taken my lapua out to 1165 with good success, but not with this load. I think this load will shot much better than the RL-19 powder. Still need to reverify my H1000 results. Couldnt shoot today to windy. It almost makes you feel like God knowing that you can achieve that kind of accuracy at those extended ranges. Anyway very nice shooting, hopefully I can share some of the same success.
 
Re: 300gr smk load info

Forgot to ask you, how do you like your Vortex PST? Looking at replacing my Weaver Grand Slam (3.5 X 10 X 40mm) with either the Weaver Tactical or the PST, something with turrets. Missed a monster muley at 575 yds this last season, still makes me sick when I think about it. It wont happen again!!
 
Re: 300gr smk load info

I love it. I have it mounted on a .300 win mag 700 Police shooting 210 Berger vlds at 2907 at muzzle. This past deer season I made 2 head shots on does and then dropped 2 does at 370 yds. One doe at 542 and a 13 pt at 412. It is clear and the clicks are true. Had one issue with it and sent it back to vortex. Had it back in 7 days. The customer service dept is great. I highly recommend their products
 
Re: 300gr smk load info

Oh yeah and all fixes are free. Regardless of what happened. In my case some turret springs had been overstressed. ( my fault). But it didn't matter. They just said ship it back and we will take care of it. I have the 6x24x50 mrad. Got the mrad bc less clicks compared to moa. It makes things quicker when you have got a big "hoss" way out. It's click value is .36 compared to .25 ( moa) so you won't be quite as precise but who cares when you have got a 7" vital area to hit!

That's a myth. If your bullet is not stable at 100 yards (causing inconsistent point of impact) there is no way it's going to correct itself further down the path.
 
Re: 300gr smk load info

Thanks for the info. I had the same thinking but, I wasn't sure. Nice lapua set up but how bad does that thing beat you up when you shoot it? The break on that is quite a bit smaller than the one on the 110 BA, not that the BA kicks bad at all but, the BA has got to weigh about 7 or 8 pounds more.
 
Re: 300gr smk load info

I shoot nosler partitions 165gr in my remington 700, not the most accurate bullet nosler makes. Have had decent results with them but, when I switch scopes I am looking at the Sierra Game Kings BTHP in the 165gr. What do you think, would like to hunt out to 600 yds with it. (Have a Lapua for anything past that, Ha, Ha!!)
 
Re: 300gr smk load info

@Daxter, the action, barrle and breake are the same between the 110BA and the 110FCP. Not sure how much the 110BA weights in at, mine as its sits is 14.5lbs. The recoil is not bad at all.
 
Re: 300gr smk load info

The 700 police mlr will jar your ass if your Lolly gagging around. But I would have to compare it to a light weight .45-70 w/o the snap. It's more of a solid push. I would much rather shoot it 20 times than a 45-70 that weighs the same. Scale of 1-10 I would give it a 7.5 on recoil. But the 40x trigger helps bc your not squirming when the gun fires
 
Re: 300gr smk load info

My Savage 110 FCP 338 LM is a pleasure to shoot. I have a thumbhole 300 WM I built years ago and it kicks like a mule compared to the Lapua.

You bettter be hugging that 300 tight or the scope will give you a kiss. The Savage is obviously heavier (probably 3.5#) but the brake and stock combo have to get a lot of credit with that cartridge.
