This is the followup on my Bergara BMR project, where the goal was to increase rifle's weight in order to help stabilize it, and get better accuracy out of it.
I was actually able to find some lead shot - I
robbed an old Caldwell bag for one of their rests of 1 lb 10 oz of it (that's how much would fit) and poured it into the
compartments in the forend, and then poured some Z-Poxy, stained with black powdered paint, over
that.
This process was very tedious - I kept coming back, probably 6 times total, with more Z-Poxy as it kept seeping in between the pellets, creating little surface bubbles I kept popping.
When I do it again (more about that later), I'll use a little less per compartment.
Overall, though, this part of the project turned out a lot
nicer than I expected, and certainly nicer than it
should have, since up until that point I was only vaguely aware of the existence of epoxy

, and mostly as something to be given a
wide berth on the account of its
unpredictability and difficulty of removing.
Unfortunately
all this tediousness has apparently exhausted my commitment to doing
quality work
, because to rebalance the rifle I just poured 1 lb 10 oz (simply same amount of weight I added to the forend) into a Ziploc bag, stuffed it into the buttstock and topped it off with a couple of sections of a paper towel for a snug fit - I wish I was making this up


, but even this
atrocity
worked out pretty well, you can only hear the shot making a racket when you bump the buttstock on a very hard surface, and
like you mean it.
Of course by now I have a fair amount of ego invested in the project and I really want the rifle to do well, so I topped it off with a Nightforce Precision Benchrest (12-42 x
56 mm), but this choice may have possibly held me back instead, because in order to accommodate the 56 mm objective I had to use high rings, which
did 2 things, both of them bad

:
* It made my cheekweld into more of a
chinweld
potentially interfering with the consistency of my shooting and with the final accuracy test results.
* The high rings combined with the 30 MOA rail made it impossible to zero the rifle at 50 yards - I ran out of adjustment, and by quite a bit - around 5 inches, so I'm joining Doug from a different recent thread in
protesting against Bergara not offering a 0 MOA - or at least "less than 30 MOA" - rail.
EGW rail is $70 AND out of stock, but, thanks to Doug

the Warne bases are on the way:t
However, until they arrive, I'm going to install a different scope - Bushnell Engage 6-24 x
50 mm, which will install with medium rings.
BTW, this scope, despite being a
"cheap" China scope, imo punches way above its weight/cost, at least for
short range rimfire applications.
A little over a year ago I picked up 2 of them for $299 each on Midway, now they're almost $500 and not readily available....
If you've read this far, you're probably
way past ready to hear the accuracy results, and, in absolute terms they are good, but not great, while representing a huge improvement over what I was able to accomplish without making the rifle heavier - the scoped rifle right now is
heavier than the original sin 
at 11.4 lbs, just the way I wanted.
The average of 5 5-shot groups was .39", with the worst one at .50" and with 3 groups in the 3s, and there even was one .15 3-shot group, but during warmup, so it's excluded from the average.
Conditions in my favor were the almost complete lack of wind, something very rare in the "winter" in Florida.
What
could have held me back?..
The stockweld, and still the relative
freshness of the bore - under 500 rds., with almost all lubed bullets, so whatever break-in needs/can take place, hasn't yet.
Also, towards the end of the session it started to
get dark.
None of the above - imo/so far - changes Bergara BMR's position v. Tikka T1X MTR, btw.
The stock mods, which were clearly necessary
for me to get decent accuracy results can't really be recommended, unless you're not going to sell the rifle, or are at peace with the prospect of having to sell it at a deep discount.
Be that is it very well may my experience with Bergara BMR influenced me to get the BXR from Buds ($549) - both Buds and Grabagun had them in stock yesterday, they're both sold out now.
The stock on the BXR looks to be the same type as BMR's stock - basically a
premium Tupperware stock, and I'll almost certainly also increase its weight, the same way.
...I'll probably come back with
more, particularly if my accuracy with the BMR continues to improve
