Rem 300 winmag 5R, throats length?

[rrflyer]

Have a Rem 5R 300 winmag with 26" tube


Was going to load up some 215 hybrids but to get them mag length they'll be jumping .35!

Anyone else playing with this? Seem normal?

Similar issue on my Milspec 5R in .308. I ended up using more jump tolerant bullets in it.

Sounds normal for a Remington chamber, lol. On a positive note if you load them long for single feeding think of all the extra case capacity you'll have

The Berger hybrids can tolerate jump. With the way I measure distance to the lands, .050" off just plain works for the Berger hybrids. 6 of the 7 rifles I load hybrids in have ended up at .050" +/- .010" off the lands. The only exception is my Lapua that likes both the 250s and 300s at .001" off.

Of note, I previously had a 26" Remington 5R 300 WM, and like my current 300 WM, both ended up with 215s seated at .050" off.

Here are my jump measurements for the rifle I use currently hybrids in.
300WM, 215 Hybrid, .050" off
.243 Win, 105 Hybrid, .040" off
338 Edge, 300 Elite, .045" off
7RM, 180 Hybrid, .045" off
7mm/300, 195 Hybrid, .050" off
300 RUM, 230 Hybrid, .060" off
338 LM, 250 and 300 Hybrids, .001" off
