    Gunsmithing Primary Extraction issue with Savage 110 BA Stealth 338 Lapua Magnum

    Usually you can't run the gap down to zero without interfering with the closing cam. You'll feel that as a click or hitch when closing the bolt on an empty chamber. If you go too far and that happens, use a sharpie on the leading corner of the bolt head that contacts the closing ramp and file...

    Ruger Enhanced Precision Rifle 223 magazine

    AICS short action pattern. They feed the RPR really well and are 2.6" internally.

    I skip bushing the firing pin to leave a reminder that I'm running a lot of pressure. I've never pierced a primer in my Savages. The bolt lift kits are a waste of money. The large bolt knobs are only ~$40 They'll never be a particularly nice gun, but they're straight forward and cheap to set...

    How did you decide that? I'll bet you read it on the internet! 80 ksi is well beyond sporty and about 10 above what stout reloads should be with the best brass. Improving the extraction timing is the trick, not a larger extractor. The last 3 R700s I've bought all had the same lack of primary...

    It could also be telling you; 3 - We're way over pressure 4 - We don't have enough primary extraction timing

    I didn't really intend to be the apologist for Savage, but I've had good luck with them as cheap mules. When there is enough time on the extraction cam, the extractor is less likely to rip rims because it's pulling the case out over a longer arc. The cases in my 33XC stop going into the...

    That's actually a pretty strong endorsement of the the Savage extractor.....

    It's pretty straight forward to adjust. The poor guy way to do it is adding some set screws to the rear bolt baffle to space it off the receiver. Bolt baffles are cheap. I shorten the bolt body on mine. And then shorten the bolt the same amount. Setting it up to center the cocking collar...

    R700 gen 2 5r action screw issue

    5/16" is a pretty standard hole size for action screws, but your pillar isn't the OPs XLR chassis. The 35 thou is also only the first dimension that was off. I have one R700 action with the rear hole off to the side enough to need the pillar opened up. I don't have any that didn't need...

    R700 gen 2 5r action screw issue

    35 thou is 0.035", 10X the thickness of a human hair or piece of paper. 35 thou x 2 is more than 1/16", so if the action screw holes in the XLR chassis are only oversized by 1/16", the clearance is gone. The action screw hole locations being off is one of the reasons we bed actions. They can...

    Sherman 7 MAX

    With your data, I'll be able to start with a pressure ladder for N570 using large rifle magnum primers rather than doing 1 for both large rifle and large rifle magnum. I get the best results with H4831 using large rifle primers. With my 300wm, the lowest velocity spreads came from large rifle...

    Sherman 7 MAX

    I've been shooting a 7/300 wsm for a few years as my ELR practice gun. I've been using 180s because I bought a big pile of them cheap and they've been effective to the last target on our range at 2300 yards. Its a short action and I load the 180s for that gun at 2.950" to mag feed. I just...

    Thanks, that'll save me a pressure ladder.

    Which primer are you using?

    The rim and extractor groove isn't supported with any action. The brass is on it's own for the length of the bolt recess, plus the bolt to barrel end clearance, plus the chamfer on the chamber. The large shank Savage tennon is as large as most dedicated 338 Lapua custom actions and has a finer...

    Will a 40 MOA rail work?

    Good catch, you might have saved yourself all kinds of pfm scope problems. Grind or file the ding down below flush from the bottom and you'll be gtg. I'll bet if you contact Ruger they'll send you a replacement. The factory rail should work well with your scope. If you switch to another with...

    Will a 40 MOA rail work?

    Sorry, I wasn't sure. I thought mine came with the zero stop bottomed to prevent that misunderstanding. It does happen with some scopes though. I was going to ask you to mail me your unused travel.

    Will a 40 MOA rail work?

    If there is a problem with the RPR out of the box, Ruger will make it right if you ask. The mount might not seem like much, but what if its the mounting holes in the receiver? A little ways down the road, Ruger might not be as accommodating. My eyes are old enough that bubble levels at the...

    Will a 40 MOA rail work?

    You're on the factory preset zero stop, that scope has nearly double that travel. Its nearly centered in its travel, so there is no need to move the turret for storage. I have one on a 338 RPR with a 20 moa one piece mount on top of the 30 moa factory rail. It has over 32 mils (110 moa) up...
