Home Forums Hunting & Shooting Ask The Gunwriters Trophy Bonded Tipped jump

I just bought two some 130gr .270 TBT bullets which I will be loading soon.

I will use H4831 and IMR 7828SSC powders with CCI BR2 primers.

I would appreciate if you could share your experience on the amount of jump that has given you the best accuracy. I was thinking on something like 0.075" away from the lands...

Thank You!

.075 has worked great for me in my 270 Win Featherweight

Beretz;

I opened the box and found Federal's little card with suggested loads and the over all length theyshow is 3.27"

In my two guns they would kiss the lands at 3.38" so Federal's data would imply a jump of 0.11"

I will load and shoot six there at Federal's 3.27" and another six at 3.305" with the same junmp that worked so well for you and see how it goes.

As to other 130gr bullets without a solid shank, how would your loads compare? I mean if you had to pour more or less amount of powder for the same speeds?

Thank You for your help.

I load mine at factory length, they shoot well.
