That really really sucks. Thier barrel replacement service in 6cm is why I decided to buy the element for my kid.
Now when i rebarrel next year she won’t be able to shoot the element in NRL factory division.
That is not the ideal setup to shoot a rifle from, especially locked in. You would be better off putting a small bag on the tripod and shooting off of the bag IMO.
The extra stability you are looking for by locking in directly to a tripod head isn’t going to be there unless you have seriously...
I think they are just fine. Folks complain about “slop” - the Magpul has some foward/back play like an atlas. That makes for a more forgiving bipod as taking “slack” out or forward loading is less critical. There isn’t any side to side play, I would suggest rotating the top of the bipod 180deg...
Only thing that works for me is to tip the rifle sideways and let gravity work. Pain in the ass. My kid has way fewer issues, I do think the speed you run the bolt affects it.
For a 21” barrel, this isn’t rocket science. Take book velocities for a 24” barrel and reduce by 75fps.
I can’t believe how much folks sweat a few inches of barrel vs velocity.
I’m running 108s/2780 in a seekins element 6cm. Could go way higher but its for my kid, soft recoil with the can...
I use a plumb bob (hang a rope with a weight or orange ribbon with the roll at the bottom). line the vertical cross hair up with the plumb bob, then cinch down the level.
One thing, if you want to be effective in the field, like all things shooting - make checking the level part of your std...
To add, if you are just shooting std NRL22 and not 22x/PRS the 5mil/rev thing is less of a big deal. If I wasn’t shooting past 250 we would still run the SWFA.
Not the 3-15, but my kid and I ran the 10x fixed side focus for a few NRL22 matches. With the concept of keeping with the same mil-quad reticle since we have SWFAs on our center fires as well.
The 10x worked very well for us mechanically and optics, but the 5mil/rev is a dealbreaker in rimfire...
I’ve got two AO lithiums for my TM that were -$550 ea. will prose ran a microwave off one for 20 min, they have a super beefy bms and wiring.
I was going to install a yandina Trollbridge lithium on my outboard to charge them from my main, then after using on the water I found the batteries...
The most practical way to get an approximation of chamber pressure is still to look at the chronograph. Max book velocity is going to correlate better to max chamber pressure than CHE, reading primers, etc.
Yes
My kid has almost no FTE, I have one about every 2 or 3 mags. She flicks the bolt back quicker or something,
Tilting the gun to dump the case works but is s bitch if you are on bipod. Typically I just cycle the bolt back again and eject a new round with the empty and it clears it. Cci sv...
I’ve not shot a 270 win much past 600, but I’ve shot a 6cm at ~1000. The 6mm 108 and the 270 145 have identical BC, I would expect similar performance (aside from a significant increase in recoil of course).
Could be the barrel opens up where they cut it, was tighter at the previous muzzle location.
I bought some lead slugs from brownells to try and check for this before I send a few barrels in to be cut and threaded. Haven’t done it yet and have no experience with it.
Just a thought.
What matters is consistency downrange, hits on target.
If folks would shoot groups at say 600yds (with reasonable sample size - say 20 rounds) and compare thrown vs trickled/weighed MANY would be very surprised that they can’t tell the difference on target.
I trickled/weighed charges for 20...
They are simply operating at different pressures. Loading to “book max” powder charge doesn’t mean your rifle is going to be at max pressure, it just means the rifle tested was at max pressure (assuming you are looking at modern load data from pressure testing)
Pressure is driving the velocity. If your barrel is faster than book max velocity, regardless of powder charge, it’s very wise to acknowledge you are over pressure.
