Tried out the Fed BOR Lock 350gr
Not happy!
I first shot them with 80gr BH209 at 100 yards and the first clean bore shot was off badly which is not cool in my book. The next 3 shot group on a fouled bore was ok, Barely under 3" group.
I figured I'd try 100gr BH209 to make up for the bullets length and that was of no help at all. The group size almost doubled.
I don't like the way the bullets load, they just ride easily on the rifling and I feel that's the reason accuracy sucks. I had this same issue with the Harvester Sabertooth bullets and the way they ride the lands.
Other than the accuracy, it was a nice cool 40* day with sun shine. Could have been worse!

Do you think with the loose fit, perhaps a change of powder might help? I was with the understanding that blackhorn 209 likes a tight fitting bullet. Perhaps good old black powder might work. Just a thought.

My wallet's learned to stick with the 295gr Powerbelt copperHPs (closeout buy) and 300gr XTPs (bulk buy). No more experimenting, unless Cecil wants to feed me a few more pks of freebie bullets. Wish I could find the Platinums on closeout. That's the best Powerbelt out there.

That's funny because I had the rifle sighted in from September with 100gr BH209 and the 338gr platinum. After the first 4 shots with the bor lock, I took a shot with the 338gr platinum and put it 1 1/2" high of the bulls eye. Same place it was during hunting season. I was happy with that.

Yes, I recovered a few bases as well. They all had rifling on them but I never looked to see how deep. I can get one off the range later and take a look. the 270 copper version shot beautifully. These, they want low doses of powder it seems. For this rifle anyway. I may have to try them in the Wolf.

Just a thought.
Does heavy seating pressure make it tighter in the bore before firing? Without wasting powder a small piece is dowel rod could be used to simulate a powder column. Seat one easily on a dowel rod. Remove the plug and dowel rod. Try to push it back out from the breach end.
Repeat with a BOR-Lock seated heavily on the dowel rod....Is it harder to push out now?
Inquiring minds want to know

Just a thought: Did the 350 gr. and 270 gr. seem to load w/similar force? Just wondering if the 350 w/the heavier powder charge and a loose bore is allowing the rubber base to expand too much in the bore(maybe creating blowby) in conjunction w/the extra weight of the slug. The lower charge would effect the rubber base less, possibly being the reason 80 gr. works better. Do you still have both examples to do a mic comparison?
