Bergara B14 HMR accuracy test

[Mike D]

I was pretty excited about the 45 raptor, but my friend got one and had hell getting it to work right. Straight wall cases don't seem to feed great in the AR, plus you have to mod the hell out of your mags and it uses 452 bullets instead of 458s.

I'd love to see a 458 bullet in a bottleneck case for the AR10 that packs enough powder to rival the 45-70. I'd get a 10-12" SBR in that to throw 500-600 grain subsonics.

458 Socom will do that. I have some 500 grain subs running at 1030fps out of an 11” SBR.

My 300 grain Barnes runs at 1800fps.

Alexander let Lapua finish out the cartridge, the shoulder was changed for more case capacity. Lapua was already making 220 Russian brass so they changed from 6 PPC to 220 Russian for a parent case. Imagine that, a corporate inside job.



Bill left Alexander Arms last year, going to to bigger and better things.

Isn’t the 220 Russian the parent case for the 6 PPC (not that it matters)?

Of Arne is involved in this my interest just went up. He and Bill Alexander developed the 6.5 Grendel. They had a falling out because Arne wanted to go SAMMI and release it, while Bill wanted to keep it inhouse so it would not get a bad name.

I bought my first Grendel from Arne.

Yeah, both of the raptors are Arne's. Though I should say that the .375 is pretty similar to the .375-08 jaguar wildcat.

Yeah I've thought about getting one, but I've already got two SBR uppers for my AR15 and my AR10 is feeling lonely. Need to make that tax stamp earn its money.

Next toy........LabRadar

Nice! I’ve been looking at those.
My Magnetospeed is great, but I like the idea of being able to shoot groups and chrono at the same time. It looks like there may be a bit of a trade off though with the space you need to get the LabRadar next to the end of your barrel. Definitely won’t work at the indoor range where I often go for convenience on my lunch hour.

Watch that Lapua brass- tiny flash holes. Heard of more than one person not realizing that and breaking decapping pins.

Looks like these are pretty roomy.
